Executive Summary
Together, the West Valley Water District (the District) and the City of Rialto (the City) provide
water for residential and commercial/industrial uses in the City of Rialto. In recent years,
perchlorate has been detected in several of the District’s and City’s production wells at
concentrations exceeding the notification level and maximum contaminant level (MCL) of
six micrograms per liter (µg/L) established by the California Department of Public Health
(CDPH). The District and City have removed these production wells from service, pending
installation of appropriate treatment systems. Treatment systems are being developed for two of
the production wells, Rialto Well No. 6 and District Well No. 11.
This human health risk assessment (HHRA) was performed to estimate the potential human
health risks associated with domestic use of untreated groundwater from the Rialto Well No. 6
and District Well No. 11, assuming that no reduction in the concentrations of contaminants
occurs through treatment or response actions. The objective of the HHRA is to provide an
analysis of baseline risks, which are defined as the “risks that might exist if no remediation or
institutional controls were applied at a site” (United States Environmental Protection Agency
[USEPA] 1989). This HHRA has assumed that no treatment has been conducted, consistent
with the appropriate state and Federal guidance, and although risk values have been calculated
as a result of several COPCs, many of these COPCs are present in groundwater at levels less
than State and Federal drinking water standards.
The chemicals of potential concern (COPCs) for quantitative risk assessment were selected in
accordance with USEPA risk assessment guidelines (USEPA 1989). The chemicals identified
as COPCs for further evaluation in the HHRA were:
Inorganic anions: perchlorate, nitrate as nitrogen (NO3-N), and fluoride.
Metals: arsenic and hexavalent chromium.
VOCs: 1,2-dibromo-3-chloropropane (DBCP), chloroform, and trichloroethene (TCE).
Of these COPCs, only perchlorate, NO3-N, and TCE were detected at concentrations above the
respective California primary maximum contaminant level (MCL).
Potentially exposed populations for evaluation in the HHRA were identified based on
consideration of the current and future use category and USEPA (1989) guidance. Because
Rialto Well No. 6 is not currently used for domestic supply and District Well No. 11 is provided
with treatment, the only potentially exposed populations are under future use conditions if the
production wells were restored to service without treatment. The HHRA considered potential
future exposures for adult and child water consumers (Adult and Child Residents) via ingestion
of, inhalation of, and dermal contact with COPCs in groundwater used as a domestic water
source.
The groundwater data used in this HHRA were obtained from the historical water quality
database maintained by CDPH, which requires all certified drinking water analytical laboratories
to submit water quality data directly to CDPH in electronic form. Studies not requiring reporting
to CDPH were not included in the HHRA data set. Groundwater data collected from Rialto Well

No. 6 and District Well No. 11 were used to develop exposure point concentrations (EPCs) for
use in this HHRA. Trend analysis was used to determine the appropriate data set for use in
HHRA so that the EPCs represented a stable trend in concentrations.
Both noncarcinogenic and carcinogenic health effects were evaluated in this HHRA. For
noncarcinogenic effects, hazard quotients (HQs) were calculated by comparing the estimated
average daily intakes of COPCs to toxicity value benchmarks that represent exposures that
would not cause adverse health effects, even if the exposure occurred continuously over a
lifetime. Estimated HQs were compared to the point of departure of 1 established by the
California Department of Toxic Substances Control (DTSC). For carcinogenic effects,
incremental cancer risks were calculated by combining the estimated lifetime average daily
intakes of COPCs with chemical-specific dose-response data. Incremental cancer risks were
compared to the DTSC point of departure of 1 x 10-6.
The results of the risk characterization for the production wells Rialto Well No. 6 and District
Well No. 11 are summarized as follows:
Rialto Well No. 6. TCE, chloroform, and perchlorate are the chemicals found to exceed the
DTSC point of departure for carcinogenic or noncarcinogenic effects for Rialto Well No. 6. TCE
and chloroform resulted in cancer risk estimates exceeding the DTSC point of departure of
1 x 10-6. For the combined adult and child resident exposure scenario the cancer risk estimates
for TCE and chloroform were 3 x10-6 and 2 x 10-6, respectively. Perchlorate was the only COPC
that resulted in a HQ greater than the point of departure of 1.
District Well No. 11. DBCP and arsenic are the chemicals found to exceed the DTSC point of
departure for carcinogenic effects for District Well No. 11. DBCP and arsenic are the chemicals
associated with cancer risks greater than the DTSC point of departure of 1 x 10-6. For the
combined adult and child resident exposure scenario, the cancer risk estimates for DBCP and
arsenic were 2 x10-5 and 3 x 10-5, respectively. No COPCs resulted in a HQ greater than the
point of departure of 1.
Of the chemicals found to exceed the DTSC points of departure for carcinogenic and
noncarcinogenic effects, only the TCE and perchlorate EPCs were above the California MCLs.
DBCP is a halogenated volatile organic compound (VOC) that was historically used as a soil
fumigant for agricultural purposes, although it has not been approved for use in agriculture in
California since 1977 (California Office of Environmental Health Hazard Assessment [OEHHA]
1999). The California Department of Pesticide Regulation (CDPR) reported detections of DBCP
in all of the 261 wells that were tested for DBCP (2009). The concentrations of DBCP detected
in groundwater collected from District Well No. 11 are similar to concentrations commonly
detected in groundwater as reported by CDPR (2009). The DBCP EPC for District Well No. 11
(0.032 µg/L) was based on the maximum detected concentration, which is almost one order of
magnitude less than the California MCL for DBCP of 0.2 µg/L.
CDPH (2008) states that arsenic is ubiquitous in nature and is commonly found in drinking water
sources in California. The arsenic EPC for District Well No. 11 (1.2 µg/L) was based on the
maximum detected concentration and is less than the California MCL for arsenic of 10 µg/L.

Section 1: Introduction
Kennedy/Jenks Consultants (Kennedy/Jenks) has prepared this Human Health Risk
Assessment Report (HHRA report) on behalf of the West Valley Water District (the District) and
the City of Rialto (the City). This HHRA report presents the evaluation of potential human health
risks associated with domestic use of groundwater from two production wells (Rialto Well No. 6
and District Well No. 11), assuming that the wells were restored to service and no reduction in
the concentrations of contaminants occurs through treatment or response actions. The goal of
the HHRA is to provide an analysis of baseline risks, which are defined as the “risks that might
exist if no remediation or institutional controls were applied at a site” (United States
Environmental Protection Agency [USEPA] 1989). Therefore, this HHRA evaluated baseline
risks for the two production wells as the risks that might exist if the groundwater was used
without any pretreatment or reduction in contaminants through response actions.
1.1 Background and Regulatory Context
Together, the District and the City provide water for residential and commercial/industrial uses in
the City of Rialto. The District and the City obtain water from several different sources, including
groundwater wells, surface water sources and the State Water Project; however, groundwater
accounts for more than two thirds of these supplies (ERSC 2006, Egan 2006). In recent years,
perchlorate has been detected in several of the District’s and City’s production wells at
concentrations exceeding the maximum contaminant level (MCL) of six micrograms per liter
(µg/L) established by the California Department of Public Health (CDPH). The District and City
have removed these production wells from service, pending installation of appropriate treatment
systems. The loss of these wells has made it challenging for the District and the City to maintain
operational flexibility and to meet seasonal peak water demands.
Accordingly, the City and the District have established a cooperative agreement to restore two
of the production wells to service. Under this agreement, the District has taken the lead for the
planned construction and operation of a groundwater wellhead treatment system that will
remove perchlorate and nitrate from groundwater, and reduce volatile organic compound (VOC)
concentrations in groundwater. Groundwater pumped from Rialto Well No. 6 (located off
Etiwanda Avenue in Rialto) and District Well No. 11 (located off Willow Avenue in Rialto) will be
conveyed approximately 6,300 linear feet via existing and new underground pipelines to a
treatment facility to be constructed at the District’s headquarters, located at 855 West Base Line
Road, Rialto, California. The wellhead treatment system and associated piping will be referred
to herein as the Project. Upon successful completion of a required initial startup demonstration
period (of up to one year) to be overseen by CDPH, approximately 2,000 gallons per minute
(gpm) of treated groundwater will be restored to the District’s drinking water supply for
distribution. Figure 1 provides a map of the general area.
The Project will be implemented at the same time as other perchlorate cleanup projects in the
vicinity. In particular, a 160-acre parcel located on the corner of West Casa Grande Drive and
Locust Avenue in Rialto was previously identified by the USEPA as a Superfund site under the
federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)
(USEPA 2009a). Cleanup activities at and near the 160-acre site are focusing on remediating
the source of contamination.

Page 1
The wells to be used by the District and the City for the Project are not part of the Superfund
site; however, they are located immediately downgradient of the 160-acre parcel. Therefore, the
District and the City plan to implement the Project in accordance with applicable requirements of
Superfund, and regulations set forth in the National Contingency Plan (NCP) (40 Code of
Federal Regulations [CFR], Part 300). Typically, when a cleanup project is implemented in
accordance with the NCP, an environmental regulatory agency (such as the USEPA or the
California Department of Toxic Substances Control [DTSC]) assumes responsibility for
overseeing the investigation and cleanup activities. In this case, however, none of the agencies
with a potential interest in the Project has requested an oversight agreement. Therefore the City
will serve as the primary Project reviewer, and will accept comments from the agencies if
provided. Concurrent with the NCP process, the District and the City will pursue from CDPH the
required permit for restoring an impaired water source for use as public water supply, as
directed in CDPH Policy Memo 97-005, Policy Guidance for Direct Domestic Use of Extremely
Impaired Sources (CDPH 1997).
1.2 HHRA Objectives
The general objective of a HHRA is to characterize the risks to human health that may be posed
by chemicals present in or entering into environmental media (e.g., groundwater, surface water,
air, or soil). The objective of the HHRA is to provide an analysis of baseline risks, which are
defined as the “risks that might exist if no remediation or institutional controls were applied at a
site” (USEPA 1989). The results of a HHRA help to establish acceptable exposure levels for use
in developing appropriate response actions.
The specific objective of this HHRA was to estimate the potential human health risks associated
with domestic use of groundwater from two production wells (Rialto Well No. 6 and District
Well No. 11), assuming that the wells were restored to service and no reduction in the
concentrations of contaminants occurs through treatment or response actions. The objectives of
the HHRA were to:
●
●
●
●
●
Identify and select chemicals of potential concern (COPCs).
Identify and estimate potential exposure pathways to individuals who may come in
contact with COPCs in groundwater from the two production wells.
Characterize potentially exposed populations and estimate the extent of their exposure
to COPCs in groundwater from the two production wells.
Identify the potential cancer risk and health hazards associated with the COPCs.
Quantitatively characterize the noncarcinogenic and carcinogenic risks to the potentially
exposed human populations posed by the COPCs in groundwater from the two
production wells.
Figure 2 provides a general schematic that outlines the process that was followed in this HHRA
to estimate the potential human health risks associated with domestic use of groundwater from
the two production wells.
1.3
HHRA Approach
The approach and methods that were used to perform this HHRA were consistent with risk
assessment guidance published by the DTSC, and with similar guidance from the USEPA for

issues not addressed by the State of California. The HHRA incorporated health-protective
assumptions in estimating the potential health risk associated with domestic use of water from
the two production wells (Rialto Well No. 6 and District Well No. 11).

Section 2: Background and Description of Area
This section presents a description of the project area, water supply sources, and background
information on the two production wells.
2.1
Description of Area
The Project site is located in the City of Rialto, San Bernardino County, California,
approximately 60 miles east of Los Angeles (Figure 1). The City is situated in the San
Bernardino Valley, within the Santa Ana River Basin Watershed (ERSC 2006). The population
of the City as of 2008 was approximately 100,000. Land use in the area during the first half of
the 20th century was mostly agricultural, but is now dominantly residential, industrial, and
commercial. The land surface slopes gently to the southeast from a high of approximately
2,000 feet above sea level at the base of the San Gabriel Mountains, to a low of approximately
950 feet near the Santa Ana River. The elevation at the Project site is approximately 1,300 feet
above sea level.
2.2
Water Supply in the Rialto Area
The Project site is located in the central part of the Rialto Colton Basin (RCB), one of several
groundwater basins associated with the San Bernardino sedimentary basin (Figure 1).
Groundwater has been a primary water source in the region for decades, and the RCB has
provided a substantial portion of the overall groundwater supply. In addition to the District and
the City, the City of Colton and Fontana Water Company also produce significant amounts of
groundwater from the RCB.
The District service area is split into northern and southern portions by the City’s service area
(Figure 3). Approximately one-half of the City residents are served by the District (ERSC 2006,
Egan 2006). The three primary sources of water for the District are local surface water,
groundwater, and water imported from the State Water Project. The District’s total water
demand for the period 2000-2004 ranged from 19,698 to 22,374 acre-feet per year (AFY), with
groundwater supplying between 56 and 72 percent of the total demand (ERSC 2006).
The City uses the same three water sources as the District, plus additional water from the San
Bernardino Valley Municipal Water District. The City’s total water demand for the period
2000-2004 ranged from 13,927 to 14,281 AFY, with groundwater supplying between 64 and
73 percent of the total demand. The City also supplied approximately 2,500 AFY to the
Marygold Mutual Water Company (Egan 2006).
2.2.1
Rialto Well No. 6
Rialto Well No. 6 (1S/5W-2G1) is located approximately 300 feet north of W. Etiwanda Avenue
and 670 feet west of N. Riverside Avenue in Rialto. Drilling for Rialto Well No. 6 was completed
on 15 March 1989. The total depth of the borehole for Rialto Well No. 6 is 1,000 feet, and the
well casing has two perforated, or screened, intervals. The depths of these screened intervals
below land surface are 440-830 feet and 930-970 feet. The reported pumping capacity of Rialto
Well No. 6 is 2,510 gpm with production and permitted capacities of 3.61 million gallons per day
(mgd) (Egan 2006).

Section 3: Identification of Chemicals of Potential Concern
Water quality data for the Rialto Well No. 6 and District Well No. 11 were obtained from the
historical water quality database maintained by CDPH, which requires all certified drinking water
analytical laboratories to submit water quality data directly to CDPH in electronic form. Studies
not requiring reporting to CDPH were not included in the HHRA data set. The water quality data
are included in Appendix A.
3.1
Available Data and Data Reduction
Water quality monitoring data for Rialto Well No. 6 and District Well No. 11 were evaluated in
this HHRA. Water quality monitoring data include analytes required by Title 22 of the California
Code of Regulations for community water systems. To focus the HHRA on more current
conditions, the HHRA only evaluated data collected during the period of 1999 through 2010.
Samples in the data set collected on the same day were assumed to be duplicates. Field
duplicate samples were reduced as follows:

If analytical results for both samples were detected values, the maximum detected
concentration was used in the exposure point concentration (EPC) calculations

If the analytical result for one sample was a detected value and the other sample was a
non-detect, the detected value was used in the EPC calculations

If analytical results for both samples were non-detects, the lower reporting limit (RL) was
used as a non-detect in the EPC calculations.
For cases in which a non-detected result was reported, but the method detection limit was not
listed in the database, the detection limit for reporting (DLR) for drinking water analysis under
the CDPH was assumed to be the detection limit (CDPH 2010).
Finally, the different nitrogen species reported in the data set were revised for evaluation
purposes. Specifically, the detected concentrations for samples analyzed for nitrate (NO3) as
nitrate were converted to results reported as nitrate as nitrogen (NO3-N) using a conversion
factor of 4.4, in order to compile these results with other data based on methods analyzing for
NO3-N. Uncertainties associated with this conversion are discussed in Section 7.1. Both
dissolved nitrate and unfiltered nitrate results were assessed as the same constituent without
adjustments to either result. The uncertainties associated with this assumption are also
discussed in Section 7.1. The results reported as a combination of both nitrate and nitrite (as
nitrogen) were not used in this HHRA due to uncertainties with the toxicity of the mixture of
nitrogen species.
3.2
Identification and Selection of Chemicals of Potential
Concern
The COPCs for quantitative risk assessment were selected in accordance with USEPA risk
assessment guidelines (USEPA 1989). The COPCs are a subset of the chemicals detected in

Page 7
groundwater samples collected from the two production wells. An iterative, multi-step process
was used to review all detected chemicals to focus on those chemicals that may contribute
appreciably to potential health risks associated with domestic use of groundwater from the two
production wells, assuming that no reduction in the concentration of contaminants occurs
through treatment or response actions.
3.2.1 Carcinogenic Classification
Following USEPA (1989) guidelines, detected chemicals with a USEPA carcinogenic
classification of A or classified as carcinogenic using USEPA’s Guidelines for Carcinogen Risk
Assessment (2005), were retained as COPCs based on the carcinogenic screen.
3.2.2 Frequency of Detection
The frequency of detection was used as a criterion for identifying chemicals that present a
greater potential for exposure to the potential receptor population. Chemicals detected in more
than 5 percent of the samples (with a sample population of at least 20) were initially selected as
COPCs, or eliminated if detected in less than 5 percent of the samples at low concentrations
(USEPA 1989) (with the exception of Group A carcinogens).
3.2.3 Comparison with Risk-Based Levels
To further screen the candidate chemicals that were not eliminated as COPCs during evaluation
of the screening criteria listed above, a risk-based benchmark value screen was performed. The
objective of the risk-based benchmark value screen is to identify chemicals in a particular
medium (e.g., groundwater) that (based on concentration and toxicity) are most likely to
contribute significantly to risks calculated for exposure scenarios involving that medium. Thus,
the preliminary HHRA focuses on the “most significant” chemicals (USEPA 1989).
The maximum concentrations of the remaining candidate COPCs were compared to the
screening benchmark. If the maximum detected concentration was less than the benchmark, the
chemical was eliminated as a COPC under current and future exposure scenarios for purposes
of this HHRA.
The health-based screening criteria were selected according to a hierarchy. If available, public
health goals (PHGs) established by the California Office of Environmental Health Hazard
Assessment (OEHHA) were used as the screening benchmark. PHGs represent concentrations
of drinking water contaminants that pose no significant health risk if consumed for a lifetime,
based on current risk assessment principles, practices, and methods. If a PHG has not been
established, then the USEPA (2010a) Regional Screening Level (RSL) for tap water was used.
RSLs are generic risk-based concentrations derived from standardized risk equations and
USEPA toxicity data.
3.3
Chemicals of Potential Concern
The results of the COPC screening evaluation are summarized in Table 1. The chemicals
identified as COPCs for further evaluation in the HHRA were:
Inorganic anions: perchlorate, NO3-N, and fluoride

Metals: arsenic and hexavalent chromium
Volatile organic compounds (VOCs): 1,2-dibromo-3-chloropropane (DBCP), chloroform, and
trichloroethene (TCE).
Of these COPCs, only perchlorate, NO3-N, and TCE were detected at concentrations above the
respective California primary MCL.

Section 4: Exposure Assessment
The objective of the exposure assessment was to evaluate the ways people might be exposed
to COPCs (exposure pathway) and at what levels they could be exposed (dose). The exposure
assessment outline followed USEPA guidelines and used the reasonable maximum exposure
(RME) methods recommended by USEPA. The USEPA (1989) guidance has identified four
primary tasks for an exposure assessment:
●
First, identify potentially exposed human populations that may come in contact with the
COPC. This requires knowledge of (and/or making reasonable assumptions regarding)
both current and future populations.
●
Second, identify relevant exposure pathways for human populations by which potentially
exposed populations may contact COPCs originating from groundwater.
●
Third, estimate EPCs at the points of potential human contact for all identified COPCs.
EPCs for chemicals detected in groundwater were derived directly from detected
concentrations.
●
Fourth, estimate chronic daily intakes (CDI) for exposure routes and potentially exposed
populations. The CDIs were derived using the EPCs and RME assumptions regarding
such variables as exposure duration, skin absorption factors, and various parameters
that describe human activities.
The HHRA characterized the risk to human health associated with potential use of untreated
groundwater pumped from District Well No.11 and Rialto Well No. 6. The HHRA is not designed
to consider all of the potential sources of exposure to perchlorate and nitrate (such as other
beverages or food).
4.1
Identification of Potentially Exposed Populations
Potentially exposed populations for evaluation in the HHRA were identified based on
consideration of the current and future use category and USEPA (1989) guidance. Because
Rialto Well No. 6 is not currently used for domestic supply and District Well No. 11 is provided
with treatment, the only potentially exposed populations are under future use conditions if the
production wells were restored to service without treatment. The scenarios for future use
conditions consider the following potential receptors:
●
●
Adult Water Consumer (Adult Resident)
Child Water Consumer (Child Resident)
4.2
Identification of Relevant Exposure Pathways
USEPA guidance documents were used to identify relevant exposure pathways for evaluation in
the HHRA. USEPA (1989) describes exposure pathways consisting of four necessary elements:
●
Source and mechanism of chemical release
Page 10
Human Health Risk Assessment Report, Wellhead Treatment System Project,
West Valley Water District and City of Rialto
g:\is-group\admin\job\10\1089040.00_wvwd\09-reports\hhra rpt\text.doc
●
●
●
Retention or transport medium (or media in cases involving media transfer)
Point of potential human contact with the COPC-containing medium (referred to as an
exposure point)
Exposure route (e.g., ingestion) at the exposure point
The currently known and identified affected medium is groundwater from the two production
wells. The exposure points are the locations where potentially exposed populations may come
in direct contact with the detected chemicals. The exposure routes are defined as the physical
pathways through which chemicals may enter the human body (e.g., ingestion, inhalation,
dermal absorption). This HHRA followed USEPA guidance by identifying exposure points and
potential exposure routes for both current and reasonably foreseeable future land use
conditions.
The potential exposure pathways that were evaluated in the HHRA included:
●
●
●
Ingestion of COPCs in groundwater
Inhalation of COPCs from groundwater
Dermal contact with COPCs in groundwater
A pathway is considered “complete” if there is a source or chemical release from a source, an
exposure point where contact can occur, and an exposure route by which contact can occur.
Because the depth to groundwater in the Basin is greater than 15 feet below ground surface,
the only potential exposure points would be when the groundwater is pumped to the surface for
domestic use.
The conceptual site model representing all potentially exposed populations and complete
exposure pathways is shown on Figure 4.
4.3
Process to Estimate Exposure Point Concentrations
The EPC represents the chemical concentration in the exposure medium (e.g., groundwater)
that the receptor will potentially come into contact with during the exposure duration
(e.g., 30 years for an adult resident). A trend analysis was performed on COPCs at each well to
determine the appropriate data set for each EPC calculation. When a COPC was detected at
least five times since 1999, and showed an upward or downward trend over time, historic data
were removed from the dataset so that only the most recent, stable results were used in the
EPC calculations. The exception is for TCE at the District Well No.11 exposure point, for which
a trend extends to the most recent sampling event. For TCE at the District Well No.11 exposure
point, the maximum detected concentration was conservatively used as the EPC. The results of
the trend analysis are provided in Appendix B. The date ranges for the data sets used for each
EPC calculation and the resulting EPCs are shown in Table 2.
DTSC (1996) defines the EPC as the lesser of the maximum-detected concentration and the
95 percent upper confidence limit of the arithmetic mean (95% UCL) of sample data. The 95%
UCL values were calculated using the USEPA software ProUCL (Version 4.00.05).
USEPA (2010b) recommends not using substitution methods (e.g., one-half the detection limit
substitution method) for managing non-detect values in the data set. ProUCL (Version 4.00.05)
performs EPC calculations incorporating data reported as non-detects by using estimation

Page 11
methods (e.g., regression on order statistics and Kaplan-Meier methods) instead of using
substitution methods (USEPA 2010b). Data reported as non-detect concentrations were
managed in accordance with ProUCL User’s Guide (USEPA 2010b). The ProUCL output files
are included in Appendix C.
Environmental media concentrations often show lognormal or other non-normal distributions.
The groundwater data were tested for normal, gamma, and lognormal distributions using the
current version of ProUCL. Data were tested first for normality, then for gamma distributions,
and finally for lognormal distributions, as recommended by ProUCL guidance (USEPA 2010b).
The 95% UCL was then determined and used as the EPC based on the recommendations from
ProUCL guidance (USEPA 2010b). If the data set did not contain enough detected
concentrations to calculate a 95% UCL using ProUCL, then the maximum detected
concentration was used as the EPC.
4.4
Process to Estimate Chronic Daily Intakes
For oral and dermal exposure pathways, intakes of COPCs by potentially exposed receptors
were quantified in the HHRA by estimating the mass of substance taken into the body per unit
body weight per unit time (milligrams per kilogram per day [mg/kg-day]). For the inhalation
exposure pathway, intakes of COPCs by potentially exposed receptors were quantified in the
HHRA by estimating a time-weighted exposure concentration (EC) that takes into consideration
the exposure time, frequency, and duration for each receptor being evaluated as well as the
period over which the exposure is averaged (i.e., the averaging time [AT]). The CDI (i.e., dose)
for each exposure medium was calculated using media-specific equations based on exposure
parameters that represent the duration of exposure, frequency of exposure, and other factors
that affect overall intake.
The methodology for incorporating the averaging time term in the dose equations was
consistent with USEPA (1989) HHRA guidelines. For noncarcinogenic COPCs, the CDI is
averaged over the duration of the exposure to the COPC. For evaluation of carcinogenic
COPCs, the CDI is expressed as a lifetime average daily intake (LADI) because dose is
averaged over the entire lifetime. The USEPA (1989) states that the approach for carcinogens is
based on the assumption that a high dose received over a short period of time is equivalent to a
corresponding low dose spread over a lifetime.
The calculated LADI for the adult resident is greater than the LADI for the child resident
because the length of exposure is greater for the adult resident compared to the child resident
while the averaging time term is the same (see Table 3). As presented in Section 5, the cancer
risk estimates are greater for the adult resident relative to the child resident due to the
methodology in calculating the LADI. In contrast, for noncarcinogenic exposures, the CDI for the
child resident is greater than the CDI for the adult resident because the averaging time terms
are based on the exposure duration. As a result, the noncancer hazards are greater for the child
resident relative to the adult resident.
4.4.1 Route-Specific Assumptions
Ingestion, inhalation, and dermal contact are complete exposure pathways for future use of
groundwater as a domestic supply. The route-specific assumptions are presented in Tables 3
and 4 and discussed below.
Page 12
Human Health Risk Assessment Report, Wellhead Treatment System Project,
West Valley Water District and City of Rialto
g:\is-group\admin\job\10\1089040.00_wvwd\09-reports\hhra rpt\text.doc
4.4.1.1
Ingestion of Groundwater
Ingestion of groundwater occurs through daily water consumption, including beverages made
using drinking water. USEPA recommendations were used in calculating the chemical intake
from ingestion of groundwater. Contaminated groundwater was assumed to be the only source
of water for potentially exposed populations. The daily water consumption rates were 2 liters per
day (L/day) for adults and 1.5 L/day for children (USEPA 1997).
4.4.1.2
Inhalation of Vapors
Exposure to COPCs in water via inhalation of vapors occurs during uses of domestic water
(e.g., showering) and is dependent on the volatilization of the COPC, the inhalation rate, and the
exposure duration. As was assumed in establishing RSLs for tap water, inhalation of vapors
from groundwater was only considered a complete exposure pathway for COPCs with a Henry’s
Law constant of 1 x 10-5 atm-m3/mole or greater and with a molecular weight less than
200 grams/mole (USEPA 2010a). For this HHRA, the COPCs that are classified as volatile and
for which inhalation of vapors is considered a potentially complete exposure pathway are DBCP,
chloroform, and TCE.
A volatilization factor (VFw) of 0.5 liters per cubic meter (0.5 L/m3) was used to derive a COPC
concentration in indoor air based on the COPC concentration in the domestic water. The VFw of
0.5 L/m3 is based on USEPA (1991) guidance and is used by USEPA (2010a) in the derivation
of the RSLs. It was assumed that inhalation of vapors from domestic uses of groundwater
occurs 24 hours per day.
4.4.1.3
Dermal Contact with Groundwater
Exposure to COPCs in water via dermal contact occurs during bathing and showering and is
dependent on the dermal permeability of the COPC, the body area exposed, and the exposure
duration. USEPA recommendations were used in calculating chemical intake through dermal
contact. The exposed body area for bathing and showering was assumed to be 23,000 square
centimeters (cm2) for adults and 10,000 cm2 for children. One of the parameters in the intake
equations for dermal contact with groundwater is the absorbed dose per event (DAevent). This
parameter was derived per EPA guidance (2004) using chemical-specific factors, which are
presented in Table 4. The chemical specific factors used in the calculation of DAevent were
obtained from Appendix B (Screening Tables and Reference Values for the Water Pathway) of
USEPA’s Supplemental Guidance for Dermal Risk Assessment (2004).
4.4.2 Chronic Daily Intake Equations
The equations and exposure parameters used to calculate the CDI or LADI for complete
exposure pathways for potentially exposed receptor populations under current and future landuse scenarios are presented in Tables 3 and 4 discussed below. The human intake equations
were derived from USEPA guidance (USEPA 1989, 1991). For inhalation exposures, a
concentration-based approach is used to assess risks for consistency with the inhalation
dosimetry methodology (USEPA 2009).

Ingestion of Chemicals in Groundwater
The CDI or LADI of chemicals in groundwater via ingestion is estimated by:

Where:
EPC = chemical concentration in water (mg/L)

Section 5: Toxicity Assessment
The purpose of the toxicity assessment is to evaluate the potential for each COPC to cause
adverse effects in those individuals who potentially could be exposed over an extended period
of time. Adverse chronic health effects in humans include both noncarcinogenic and
carcinogenic health effects. This section presents the approach that was used to evaluate both
noncarcinogenic and carcinogenic health effects of the COPCs selected for quantitative
evaluation in the HHRA. Noncarcinogenic and carcinogenic toxicity values are presented in
Tables 5 and 6, respectively. Toxicity values for the inhalation pathway are only presented for
volatile COPCs.
5.1
Sources of Toxicity Values
Toxicity values that describe the relationship between exposure to a chemical and the
associated increased likelihood of adverse effects were compiled. Toxicity values provided by
Cal EPA (OEHHA 2010) were used as the primary source of toxicity values for the HHRA. If Cal
EPA did not provide toxicity values for a COPC, then toxicity values were obtained from
USEPA’s Integrated Risk Information System (IRIS) database, which is USEPA’s preferred
source of information because IRIS represents the official agency scientific position regarding
the toxicity of the chemicals based on the data available at the time of the review
(USEPA 2003).
5.2
Chemicals of Potential Concern with Noncarcinogenic
Effects
Oral reference doses (RfDs) and reference concentrations for inhalation (RfCs) are toxicity
values developed for chemicals exhibiting noncarcinogenic effects. RfDs and RfCs are usually
derived from no-observable-adverse-effect levels (NOAELs) taken either from human studies,
often involving workplace exposures, or from animal studies, and are adjusted downward using
uncertainty or modifying factors. For example, a modifying factor of 2 to 10 may be applied if the
database on a particular COPC lacks information on possible reproductive or developmental
toxicity.
Uncertainty factors are generally applied to adjust for the possibility that humans are more
sensitive than experimental animals and that there may be sensitive subpopulations
(e.g., children, pregnant women, individuals with hay fever, or asthma). Depending upon the
information available, other factors may also be applied. RfDs and RfCs are intended as
conservative estimates of the daily exposure to a COPC that would not cause adverse effects
even if exposure occurs continuously over a lifetime.
Table 5 presents the toxicity values used in this HHRA to evaluate noncarcinogenic health
effects. The following sections provide additional detail on noncarcinogenic health effects for the
COPCs.

5.2.1 1,2-Dibromo-3-chloropropane
OEHHA developed a public health protective water concentration for DBCP (0.2 µg/L) based on
a noncarcinogenic toxic endpoint (OEHHA 1999). OEHHA (1999) identified testicular effects as
the most sensitive noncarcinogenic toxic endpoint, based on toxicity studies of test animals. The
NOAEL derived from this test animal study was 0.025 mg/kg-day. OEHHA applied an
uncertainty factor of 1,000 to the NOAEL (10 for interspecies variability, 10 for intraspecies
variability, and 10 for the use of a subchronic NOAEL) in the development of the public health
protective water concentration for DBCP based on a noncarcinogenic toxic endpoint. The oral
RfD for DBCP (0.000025 mg/kg-day) used in this HHRA is derived from the NOAEL
(0.025 mg/kg-day) divided by an uncertainty factor of 1,000. The inhalation RfC used in this
HHRA for DBCP (2.0 x 10-4 milligrams per cubic meter [mg/m3]) was obtained from the IRIS
database (USEPA 2010c).
5.2.2 Arsenic
OEHHA (2004a) developed a noncarcinogenic health protective value for arsenic of 0.9 μg/L
based on vascular effects in a human epidemiological study of cerebrovascular disease.
OEHHA (2004a) used a benchmark dose approach to derive this value based on the lower
bound of the lowest effective dose of 3.0 milligrams per liter (mg/L)-year with an uncertainty
factor of 10 and a relative source contribution of 0.2. The studies cited in OEHHA (2004a) do
not provide sufficient information to calculate an oral RfD. The oral RfD (0.0003 mg/kg-day) from
the IRIS database (USEPA 2010c) is based on a NOAEL of 0.009 mg/L, which is equivalent to
the lowest effective dose of 3.0 (mg/L)-year with a relative source contribution of 0.2. As a
result, the oral RfD from IRIS was used in this HHRA.
5.2.3
Chloroform
OEHHA has not developed a PHG for chloroform. The oral RfD (0.01 mg/kg-day) used for
chloroform in this HHRA was obtained from the IRIS database (USEPA 2010c). The inhalation
RfC used for chloroform in this HHRA (1.5 x10-5 mg/m3) is the chronic REL listed for chloroform
by OEHHA (2008).
5.2.4 Fluoride
OEHHA (1997a) developed a PHG for fluoride of 1 mg/L based on a NOAEL of 1 mg/L for
dental fluorosis in children. The NOAEL of 1 mg/L is also used by the USEPA (2010c) to derive
the oral RfD listed in the IRIS database. The oral RfD of 0.06 mg/kg-day listed by the USEPA
(2010c) in the IRIS database was used as the oral RfD in this HHRA. The USEPA (2010c) did
not apply uncertainty factors since the NOAEL is that of the critical effect (i.e., dental fluorosis)
in a sensitive population of humans (i.e., children) for a length of exposure that encompasses
both the critical effect and the sensitive population.
5.2.5
Hexavalent Chromium
OEHHA has not developed a PHG for hexavalent chromium. The oral RfD (3 x10-3 mg/kg-day)
used for hexavalent chromium in this HHRA was obtained from the IRIS database
(USEPA 2010c).

5.2.6 Nitrate and Nitrite
The primary adverse health effect associated with human exposure to nitrate or nitrite is
methemoglobinemia (OEHHA 1997). Methemoglobinemia is the oxidation of normal hemoglobin
to methemoglobin, which is unable to transport oxygen from the lungs to tissues. Nitrate must
be converted to nitrite to cause methemoglobinemia. The conversion of nitrate to nitrite is
mediated by bacteria in the gastrointestinal system. OEHHA (1997) identified infants as the
subpopulation that is most susceptible to nitrate-induced methemoglobinemia based on several
factors: “1) infants have a greater total fluid intake per unit body weight than adults, 2) the
gastrointestinal system in infants normally has a high pH that allows bacterial proliferation and
nitrate catalysis to nitrite, 3) frequent occurrences of infant gastroenteritis may favor the
development of methemoglobin when the upper gastrointestinal tract becomes colonized with
bacteria, 4) fetal hemoglobin is more readily oxidized than adult hemoglobin and 5) infants have
half the methemoglobin reductase activity of older children and adults and are therefore less
capable of metabolizing excess methemoglobin”.
OEHHA (1997) has adopted the following PHGs for nitrogen species:

Nitrate = 10 mg NO3-N/L = 45 mg nitrate/L,

Nitrite = 1 mg nitrite-nitrogen/L; and

Joint nitrate/nitrite = 10 mg/L, expressed on a nitrogen basis.
The PHGs are based on USEPA’s previous analysis on nitrate and nitrite, which considered “the
conversion of nitrate to nitrite, nitrite-induced formation of methomoglobin, and the general
absence of methemoglobinemia occurring at nitrate-nitrogen levels below 10 mg/L based on
worldwide epidemiological evidence”. The USEPA (2010c) lists an oral RfD for NO3-N of
1.6 mg/kg-day based on a NOAEL of 10 mg/L1. The NOAEL of 10 mg/L is based on human
studies using the most sensitive population (infants); therefore, no additional adjustment using
modifying and uncertainty factors was applied by the USEPA. The oral RfD of 1.6 mg/kg-day
was used in this HHRA to evaluate noncancer hazards for NO3-N.
5.2.7 Perchlorate
Adverse health effects observed in both test animals and humans exposed to perchlorate are
related to the disruption of thyroid hormone regulation. Animal and human studies have
demonstrated that perchlorate inhibits the “sodium-iodide symporter” (NIS), disrupts thyroidpituitary homeostatis, and causes pathological changes of the thyroid and sometimes even
thyroid tumors. OEHHA (2004b) identifies the inhibitory effect of perchlorate on the uptake of
iodide (i.e., inhibit the NIS) as the critical event for assessing perchlorate risk. The nature and
severity of the effects are related to the extent and duration of perchlorate exposure as well as
the iodine status of the individual. OEHHA (2004b) identified four sensitive subpopulations for
perchlorate toxicity: (i) pregnant women and their fetuses, especially those who are getting less

Expressed as the amount of nitrogen within the nitrite molecule commonly shown as mg NO3-N/L (1 mg
NO3-N = 4.4 mg nitrate). Doses based on ingestion of drinking water used to prepare infants'
formula: 0.64 L/day by a 4 kg infant (0.16 L/kg/day). 10 mg/L x 0.64 L/day divided by 4 kg =
1.6 mg/kg/day (USEPA 2010c).

Page 17
than a sufficient amount of iodine; (ii) lactating women, especially those who are getting less
than a sufficient amount of iodine, (iii) infants; and (iv) individuals with thyroid problems.
OEHHA (2004b) defines the benchmark dose for perchlorate as the dose that reduces mean
thyroidal iodide uptake by five percent based on the study by Geer et al. (2002) (as cited by
OEHHA 2004b). The lower limit of the benchmark dose (BMDL) is defined as the lower limit of a
one-sided 95 percent confidence interval of the benchmark dose (BMD). The estimated BMD
and BMDL are 0.0068 mg/kg-day and 0.0037 mg/kg-day, respectively. The oral RfD
(0.00037 mg/kg-day) used in this HHRA for assessing perchlorate toxicity is equal to the BMDL
of 0.0037 mg/kg-day divided by an uncertainty factor of 10. OEHHA (2004b) applied an
uncertainty factor of 10 for inter-individual variability to the BMDL to account for exposures by
sensitive subpopulations (pregnant or lactating women, infants, and individuals with thyroid
problems).
5.2.8 Trichloroethene
The primary adverse health effect associated with human exposure to TCE in drinking water is
kidney nephropathy. OEHHA (2009) presented a benchmark dose of 50 mg/kg-day, for kidney
nephropathy, as the most appropriate endpoint for derivation of a non-cancer health-protective
value. OEHHA (2009) applied an uncertainty factor of 10 for inter-species extrapolation and 10
for intraspecies variation, including potential susceptible subpopulations. The oral RfD for TCE
(0.5 mg/kg-day) used in this HHRA is equal to the benchmark dose of 50 mg/kg-day divided by
the uncertainty factor of 10 for inter-species extrapolation and 10 for intraspecies variation. The
inhalation RfC used for trichloroethene in this HHRA (0.6 mg/m3) is the chronic REL listed for
TCE by OEHHA (2008).
5.3
Chemicals of Potential Concern with Carcinogenic Effects
For carcinogenic health effects, the evaluation of a chemical involves two components: 1) a
qualitative determination of the likelihood of it being a human carcinogen and 2) a quantitative
assessment of the relationship between exposure dose and response.
5.3.1 Lines of Evidence for Carcinogenic Potential
The 1986 USEPA classification system for the characterization of the overall weight of
carcinogenicity has the following categories:

Group A: "Human Carcinogen"

Group B (1 and 2): "Probable Human Carcinogen"

Group C: "Possible Human Carcinogen"

Group D: "Not Classifiable as to Human Carcinogenicity"

Group E: “Evidence of Non-Carcinogenicity for Humans”
USEPA’s Guidelines for Carcinogen Risk Assessment (2005) emphasizes the importance of
weighing individual lines of evidence in assessing the human carcinogenic potential of COPCs.

Various types of evidence are considered in the assessment. The 2005 USEPA classification
system for the characterization of the overall weight of carcinogenicity has the following five
categories:

Carcinogenic to Humans. This category indicates strong evidence of human
carcinogenicity.

Likely to be Carcinogenic to Humans. This category indicates that there is adequate
evidence to demonstrate carcinogenic potential but does not reach the weight of
evidence for “Carcinogenic to Humans”.

Suggestive Evidence of Carcinogenic Potential. This category indicates that there is
evidence of carcinogenicity, but the data are not sufficient for a stronger conclusion.

Inadequate Information to Assess Carcinogenic Potential. This category indicates that
the available data are inadequate for applying a different category.

Not Likely to be Carcinogenic to Humans. This category indicates that the available data
are considered robust for deciding there is no basis for human hazard concern.
Table 6 presents lines of evidence for carcinogenic potential for each of the COPCs where
available.
5.3.2 Cancer Slope Factors
A COPC that exhibits carcinogenicity is generally considered by USEPA to have no threshold
(i.e., there is no dose below which a carcinogenic response, no matter how slight, might be
expressed) (USEPA 1989). USEPA uses a linear-multistage low-dose extrapolation model for
estimating cancer risk at low doses based primarily on animal data and on available
epidemiological studies. This is recognized as a conservative approach to prevent
underestimation of risk. These conservative cancer slope factors (CSFs) are commonly used in
conducting health risk assessments.
The CSF describes the increase in an individual's risk of developing cancer over a 70-year
lifetime per unit of exposure. For inhalation, USEPA (2009b) uses unit risk to describe the
increase in cancer risk. CSFs and unit risks are calculated using methods intended to be
protective of human health and are based on the assumption that cancer risks decrease linearly
with decreasing dose. The 95% UCL estimate for the slope is used in most cases to
compensate for animal to human extrapolation and other uncertainties and generally is
considered to be upper range estimates (worst case) of potential carcinogenic effects in
humans. The unit risk is the upper-bound excess cancer risk from continuous exposure to a
chemical at a concentration of 1 microgram per cubic meters (µg/m3) in air.
Table 6 presents the toxicity values used to assess carcinogenic toxicity in this HHRA.
5.4
Dermal Toxicity Assessment
Most toxicity values are based on oral, not dermal, exposures. For oral exposures, toxicity
values are often expressed as the amount of substance administered, whereas dermal

Page 19
exposures are expressed as absorbed dose. USEPA has developed a simplified method for
oral-to-dermal extrapolations (USEPA 2004). These extrapolations involve an adjustment to the
oral toxicity value based on the gastrointestinal (GI) absorption factor of the specific chemical in
the same administration vehicle (e.g., corn oil, food) as used in the critical toxicity study to
derive an estimated dermal dose.
As recommended by USEPA guidance (USEPA 2004), an adjustment to the oral toxicity factor
to account for the estimated absorbed dose was applied in the HHRA when the following
conditions were met:

The toxicity value derived from the critical study is based on an administered dose
(e.g., through diet or by delivery by forced feeding through a tube)

A scientifically defensible database demonstrates that the GI absorption of the chemical
is less than 50% in a medium similar to the one used in the critical study.
If both of these conditions were met, the oral toxicity factor was adjusted to reflect the absorbed
dose in the HHRA. For carcinogenic effects, the oral CSF was divided by the GI absorption
factor to estimate the dermal SF. For noncarcinogenic effects, the oral RfD was multiplied by the
GI absorption factor to estimate the dermal RfD. If both conditions for adjustment were not met,
the oral toxicity value was used as a surrogate for the dermal toxicity value in the HHRA.
Hexavalent chromium was the only COPC for which both conditions were met and the oral RfD
was adjusted using the GI absorption factor (0.025) for hexavalent chromium listed by USEPA
(2004).

Section 6: Risk Characterization
Risk characterization integrates the information from the exposure assessment and toxicity
assessment using a combination of qualitative and quantitative information. With this
information, risk characterization estimates the potential health risk based on the dose of a
chemical that a person may receive under certain site-specific exposure conditions and the
toxicity of that chemical. To characterize potential noncarcinogenic effects, comparisons were
made between projected intakes of substances and toxicity values. To characterize potential
carcinogenic effects, projected intakes and chemical-specific dose-response data were used to
estimate the incremental probability that an individual will develop cancer over a lifetime of
exposure.
Tables 7 through 12 present the results of the risk characterization. The following sections
discuss the methodology to calculate noncancer hazard and cancer risk estimates and the
results of the risk characterization.
6.1
Noncancer Hazard Estimates
The potential for adverse effects resulting from exposure to chemicals with noncarcinogenic
effects is generally addressed by comparing the COPC-specific average daily intake (i.e., dose)
to its RfD. This comparison was made by calculating the ratio of the estimated CDI to the
corresponding RfD to yield a hazard quotient (HQ):
HQ 
CDI
RfD
Tables 7 and 9 present the HQs separately for adult and child residents.
Estimated HQs were compared to the DTSC point of departure of 1 for noncarcinogenic effects.
HQs are typically summed across chemicals to calculate a hazard index (HI); however, the HI is
only toxicologically relevant for chemicals which have the same toxic manifestation or affect the
same target organ. Because none of the chemicals have the same toxicity endpoint for
noncarcinogenic effects, HIs were not calculated.
6.2
Cancer Risk Estimates
Potential cancer risks were assessed by multiplying the estimated LADI (i.e., lifetime dose) of a
carcinogen by its CSF. This calculated risk is expressed as the probability of an individual
developing cancer over a lifetime as a result of exposure to the potential carcinogen, and is an
estimated upper-bound incremental probability of excess individual lifetime cancer risk.
Risk  LADI * CSF
Tables 8 and 10 present the cancer risks separately for adult and child residents.

Page 21
Initially, potential cancer risks for exposure to each chemical for each exposure pathway were
estimated separately. The separate potential cancer risk estimates were summed across
chemicals and across all exposure pathways to obtain the total potential excess lifetime cancer
risk for the potentially exposed population. Estimated cancer risks for individual COPCs were
compared to the DTSC point of departure of 1 x 10-6 for carcinogenic effects.
Because cancer risks are assessed over a lifetime, the cancer risks for a combined adult and
child resident exposure scenario were calculated as using an adjustment factor of 24 years
exposure as adult/30 years exposure total:
Combined Adult and Child Resident cancer risk = Adult Resident cancer risk *
(24 Years/30 Years) + Child Resident cancer risk
Table 11 presents the cancer risk for a combined adult and child resident exposure scenario.
6.3
Risk Characterization Results
The results of the risk characterization are presented in Tables 7 through 11. Table 12 presents
a summary of the maximum and cumulative cancer risk and noncancer hazard risk estimates for
the adult and child resident exposure scenarios.
6.3.1 Adult Resident Risk Characterization Results
Tables 7 and 8 present the noncancer hazards and cancer risk estimates for the adult resident
exposure scenario for the two production wells used as a future domestic water source: Rialto
Well No. 6 and District Well No. 11.
Rialto Well No. 6. The HQ estimate for perchlorate (20) is the only HQ estimate that exceeds
the DTSC point of departure of 1 for noncarcinogenic effects (Table 7). The cancer risk estimate
for TCE (3 x 10-6) was the only individual cancer risk estimate that exceeded the DTSC point of
departure of 1 x 10-6 for carcinogenic effects (Table 8). The cumulative cancer risk estimate was
5 x 10-6, due to cancer risks from TCE and chloroform.
District Well No. 11. The HQ estimates did not exceed the DTSC point of departure of 1 for
noncarcinogenic effects (Table 7).The cancer risk estimates for DBCP (2 x 10-5) and arsenic
(2 x 10-5) exceeded the DTSC point of departure of 1 x 10-6 for carcinogenic effects (Table 8).
The cumulative cancer risk estimate was 4 x 10-5, primarily associated with DBCP and arsenic.

Tables 9 and 10 present the noncancer hazards and cancer risk estimates for the child resident
exposure scenario for the two production wells used as a future domestic water source: Rialto

the DTSC point of departure of 1 for noncarcinogenic effects (Table 9). None of the individual
cancer risk estimates exceeded the DTSC point of departure of 1 x 10-6 for carcinogenic effects
(Table 10). The cumulative cancer risk estimate was 1 x 10-6.

Section 7: Uncertainty Assessment
Uncertainty arises at every stage in the risk assessment, from the sampling and analysis of
concentrations in environmental media to the characterization of health hazard and risk. In
general, the risk assessment approach and methodology are designed to err on the side of
conservatism, i.e., protection of health. This section includes a discussion of the uncertainties
with some of the conservative assumptions, procedures, and parameters used in this HHRA.
This section identifies issues of variability and uncertainty associated with the parameters used
in the risk estimates:
●
Variability arises from true heterogeneity in characteristics such as dose-response
differences within a population, or differences in chemical concentrations in the
environment. The values of some variables used in an assessment change with time
and space, or across the population whose exposure is being estimated.
●
Uncertainty, on the other hand, represents lack of knowledge about factors such as
adverse effects or chemical concentrations. A substantial amount of uncertainty is often
inherent in environmental sampling as well as in the scientific models used in risk
assessment.
Potentially significant sources of uncertainty and variability in this HHRA that may impact the
risk estimates are discussed in the following subsections.
7.1
Uncertainties in Data and EPCs
According to USEPA guidance (USEPA 1989), the EPC should represent the arithmetic
average of the concentration that will be contacted over the exposure period. Due to uncertainty
associated with estimating an EPC, the 95 percent upper confidence limit on the arithmetic
average, which depending on the data distribution and presence of outliers can be much higher
than the arithmetic average, was used in the HHRA as the EPC. In cases when the number of
results was not sufficient to calculate an EPC, the maximum concentration was used in the
HHRA. Use of upper confidence limits or maximum concentrations provides a protective
approach and likely resulted in overestimates of the actual risks, especially for long-term
exposures.
The calculation of EPCs assumed that groundwater concentrations would remain constant over
the duration of the exposure. Trend analyses (provided in Appendix B) were performed to
determine groundwater data sets representative of stable concentrations, thereby minimizing
the uncertainty associated with future trends in groundwater concentrations. However, the
production wells are downgradient of higher groundwater concentrations, so in the absence of
treatment, it is possible that concentrations, and associated risks, could increase.
The handling of NO3-N concentrations in the data assessment also resulted in uncertainty in the
EPCs. Treating NO3-N results from unfiltered and dissolved analysis as the same constituent
caused these results to be treated as duplicates, since every dissolved nitrate analysis had an
unfiltered analysis performed on the same sample. The conversion of nitrate analytical results to
Page 24
Human Health Risk Assessment Report, Wellhead Treatment System Project,
West Valley Water District and City of Rialto
g:\is-group\admin\job\10\1089040.00_wvwd\09-reports\hhra rpt\text.doc
NO3-N concentrations also introduced uncertainty into the NO3-N EPCs, since these results
rely on different analytical methods to measure nitrogen content than methods that measure
NO3-N directly.
7.2
Uncertainties in Exposure Factors
Numerous conservative assumptions were made in selecting the exposure factors used in each
of the exposure scenarios to provide a protective estimate of risk, due to uncertainties in some
of the data used. By using conservative exposure factors (i.e., RME factors), the risk estimates
are inherently biased towards more health protective, conservative values. Actual exposures
may be lower than those assumed in this assessment.
A volatilization factor of 0.5 L/m3 was used to estimate indoor air concentrations of volatile
COPCs using groundwater concentrations. While there is a great deal of uncertainty associated
with this factor, this uncertainty is not anticipated to have a significant influence on the HHRA
results given that inhalation exposures are low relative to oral and dermal exposures.
7.3
Uncertainties in Toxicological Data
The toxicity factors used in this HHRA, which are established by state and federal policy, are
conservative estimates of the potential dose-response. In addition, the results of animal studies
are often used to predict the potential human health effects of a chemical. Extrapolation of
toxicological data from animal studies is one of the largest sources of uncertainty. Because of
these uncertainties, toxicity values are usually very conservative to be more protective of human
health due to methodologies and safety factors used by OEHHA and USEPA. The safety factors
used by OEHHA and USEPA typically range from two to three orders of magnitude (100 to
1,000 times), depending on various aspects of the animal study. As a result, actual risks are
likely to be lower than the potential risk estimates calculated in this HHRA.
Uncertainty factors are also used by OEHHA and USEPA to account for exposures by sensitive
subpopulations (e.g., infants or pregnant women). To assess noncarcinogenic toxicity of
perchlorate, OEHHA (2004b) applied an uncertainty factor of 10 for inter-individual variability to
the BMDL to account for exposures by sensitive subpopulations (pregnant or lactating women,
infants, and individuals with thyroid problems). For NO3-N, the toxicity studies used the most
sensitive population (infants); therefore, no additional adjustment using modifying and
uncertainty factors was applied by the USEPA to assess noncarcinogenic toxicity of NO3-N.
7.4
Impact of Uncertainties
When summed and used in the risk equations, these uncertainties generally provide
overestimates of risk. Resulting risk estimates are thus intentionally conservative to provide a
margin of safety in the protection of human health at a site. This must always be factored in to
the interpretation of risk estimates, as HHRAs are designed to provide guidance for
understanding the levels of COPCs that would be protective of potentially exposed human
receptor populations.

Section 8: Summary and Conclusions
This HHRA was performed to estimate the potential human health risks associated with the
future domestic use of groundwater from Rialto Well No. 6 and District Well No. 11, assuming
that no reduction in concentration of contaminants through treatment or response actions
occurs.
The estimated risks in this HHRA are based on available groundwater data for Rialto Well No. 6
and District Well No. 11 from the historical water quality database maintained by CDPH, and
DBS&A. The chemicals identified as COPCs for further evaluation in the HHRA included:
Inorganic anions: perchlorate, NO3-N, and fluoride
Metals: arsenic and hexavalent chromium
VOCs: DBCP, chloroform, and TCE.
Of these COPCs, only perchlorate, NO3-N, and TCE were detected at concentrations above the
respective California primary MCL.
Potentially exposed populations for evaluation in the HHRA were identified based on
consideration of the current and future uses of groundwater and USEPA (1989) guidance. The
exposure scenarios evaluated in this HHRA were:
●
●
Adult Water Consumer (Adult Resident)
Child Water Consumer (Child Resident)
The potential exposure pathways that were evaluated in this HHRA included:
●
●
●
Ingestion of COPCs in groundwater
Inhalation of COPCs from groundwater
Dermal contact with COPCs in groundwater
Noncancer hazards and cancer risk estimates were calculated for the adult and child residents,
and compared to the DTSC point of departure of 1 for noncancer hazards and 1 x 10-6 for
cancer risk estimates. Noncancer hazards and cancer risk estimates were calculated separately
for the two production wells. The results of the risk characterization for the production wells
Rialto Well No. 6 and District Well No. 11 are summarized as follows:
Rialto Well No. 6. TCE and chloroform resulted in cancer risk estimates exceeding the DTSC
point of departure of 1 x 10-6. For the combined adult and child resident exposure scenario, the
cancer risk estimates for TCE and chloroform were 3 x10-6 and 2 x 10-6, respectively.
Perchlorate was the only COPC that resulted in a HQ greater than the DTSC point of departure
HQ of 1.
District Well No. 11. DBCP and arsenic resulted in cancer risks greater than the DTSC point of
departure for cancer risk of 1 x 10-6. For the combined adult and child resident exposure
Page 26

g:\is-group\admin\job\10\1089040.00_wvwd\09-reports\hhra rpt\text.doc
scenario the cancer risk estimates for DBCP and arsenic were 2 x10-5 and 3 x 10-5, respectively.
DBCP was the only COPC that resulted in a HQ greater than the DTSC point of departure HQ
of 1.
Of the chemicals found to exceed the DTSC points of departure for carcinogenic and
noncarcinogenic effects, only the TCE and perchlorate EPCs were above the California MCLs.
DBCP is a halogenated VOC that was historically used as a soil fumigant for agricultural
purposes though has not been approved for use in agriculture in California since 1977
(OEHHA 1999). DBCP can be persistent in groundwater and is associated with widespread
groundwater detections (OEHHA 1999). The California Department of Pesticide Regulation
(CDPR) reported that the PHG (0.0017 µg/L) for DBCP was exceeded in all of the 261 wells
tested for DBCP (CDPR 2009). The concentrations of DBCP detected in groundwater collected
from District Well No. 11 are similar to concentrations commonly detected in groundwater as
reported by CDPR (2009). The DBCP EPC for District Well No. 11 (0.032 µg/L) was based on
the maximum detected concentration, which is below the California MCL for DBCP of 0.2 µg/L.
CDPH (2008) states that arsenic is ubiquitous in nature and is commonly found in drinking water
sources in California. The arsenic EPC for District Well No. 11 (1.2 µg/L) was based on the
maximum detected concentration and is less than the California MCL for arsenic of 10 µg/L.
As discussed in Section 1, the District has taken the lead on constructing and operating a
groundwater wellhead treatment system that will remove perchlorate and nitrate, and reduce
VOC concentrations in groundwater.

Summary: An upward trend was observed in the nitrate-nitrogen data for Rialto Well 6. Thus, only
the most recent results were used in the HHRA to determine the exposure point concentration, in
order to not include results from years in which the nitrate-nitrogen concentration in this well was
increasing, and to better represent current and future well concentrations for this analyte. Based on
the trend analysis results, the range of sample dates used in the HHRA for this analyte and well
were from 22 March 2005 to October 2010, which includes five sample results.

-1.25876 >= -1.65463 indicating no evidence of a downward trend
Summary: A downward trend was observed in the nitrate-nitrogen data for WVWD Well 11. Thus,
only the most recent results were used in the HHRA to determine the exposure point concentration,
in order to not include results from years in which the nitrate-nitrogen concentration in this well was
decreasing, and to better represent current and future well concentrations for this analyte. Based
on the trend analysis results, the range of sample dates used in the HHRA for this analyte and well
were from 8 August 2003 to October 2010, which includes 33 sample results.

Summary: An upward trend was observed in the perchlorate data for Rialto Well 6. Thus, only the
most recent results were used in the HHRA to determine the exposure point concentration, in order
to not include results from years in which the perchlorate concentration in this well was increasing,
and to better represent current and future well concentrations for this analyte. Based on the trend
analysis results, the range of sample dates used in the HHRA for this analyte and well were from 11
September 2007 to October 2010, which includes 33 sample results.

Summary: An upward trend exists for trichloroethene in Rialto Well 6 which includes the most
recent sampling results. Thus, all results in the HHRA database for this well and analyte were used
in the calculation of the HHRA exposure point concentrations. Because the trend includes the most
recent data available, the maximum concentration detected in the samples collected from Rialto
Well 6 was used as the exposure point concentration for this well in the HHRA.

Warning: There are only 3 Distinct Values in this data
There are insufficient Distinct Values to perform some GOF tests and bootstrap methods.
Those methods will return a 'N/A' value on your output display!
27
28
29
30
It is necessary to have 4 or more Distinct Values to compute bootstrap methods.
However, results obtained using 4 to 9 distinct values may not be reliable.
It is recommended to have 10-15 or more observations for accurate and meaningful bootstrap results.
31
32
33
Warning: A sample size of 'n' = 6 may not adequate enough to compute meaningful and reliable test statistics and estimates!
34
35
36
It is suggested to collect at least 8 to 10 observations using these statistical methods!
If possible compute and collect Data Quality Objectives (DQO) based sample size and analytical results.
