Our Vision
“To be recognized as the Industry Leader in Public Works”
The Regional Municipality of Peel (Peel) takes pride in ensuring that its residents are provided
with clean and safe drinking water.
The Region of Peel treats its source water to remove contaminants and regularly tests the water
quality to ensure its consumers are provided with high quality drinking water.
A number of tests were performed on thousands of water samples collected throughout the year,
including testing for microbiological, inorganic and organic parameters. The results of the tests
performed in 2013 confirm excellent quality of drinking water and have been consolidated in this
annual report.

1. General Drinking Water System Information
1.1 The Municipal Waterworks of the Community of Cheltenham, Town of Caledon
Drinking Water Works Number: 260002590 (Cheltenham Drinking Water System)
The communities of Cheltenham and Terra Cotta, with a total population served of 837, are
serviced by two municipal wells, a water storage reservoir and a distribution network of about
14.8 kilometres of watermains and 95 fire hydrants.
Cheltenham Wells No. 1 and 2 are deemed groundwater
and are housed in the same treatment building. Water
treatment includes iron and manganese removal and
disinfection. Iron and manganese are removed through
oxidation
by sodium
hypochlorite
and
potassium
permanganate followed by greensand filtration.
Sodium hypochlorite is also used for primary and
secondary disinfection.
Cheltenham drinking water system is controlled through a computerized Supervisory Control
and Data Acquisition (SCADA) system that is monitored 24 hours per day, 7 days a week.
Cheltenham wells are equipped with a stand-by power generator to ensure water treatment
operation continuity in an event of a power failure.

2. How is Water Treated?
Sodium hypochlorite and potassium permanganate are applied to the raw water pumped from
Wells No. 1 and 2 to oxidize iron and manganese which are later removed through a greensand
media filter. Filtered water is treated with sodium hypochlorite for primary and secondary
disinfection. The treated water is allowed to remain in contact with sodium hypochlorite for a
period of time to ensure effective disinfection before serving the first consumer.
Cheltenham Wells No.1 and 2 treatment process and water distribution are presented in Figure 1.

3. Region of Peel and Drinking Water Compliance in Ontario
Drinking water quality in Peel is regulated by the Ontario Government through the Ministry of
the Environment (MOE). The Ontario drinking water legislation sets requirements for municipal
system owners and operating authorities with regards to the operation, level of treatment,
sampling and testing, certification of staff and water quality notification.
3.1 Annual Water Reports
To comply with the Drinking Water Systems regulation (Ontario Regulation 170/03) under the
Safe Drinking Water Act, 2002, every year, Peel prepares Water Quality Reports that provide
information on quality of water supplied and a Summary Report regarding the operation and
performance of the drinking water systems.
The Summary Report under Schedule 22 of the Ontario Regulation 170/03 includes a statement
of compliance with the terms and conditions of the drinking water regulations under the Safe
Drinking Water Act, 2002, for Peel’s drinking water systems and a summary of the quantities
and flow rates of water supplied. This report is made available to Regional Council by March 31
of each year.
The Water Quality Reports and Summary Report are made available to the public to ensure Peel
consumers are kept informed. Each year, the reports are posted on the Region of Peel’s web site
(http://www.peelregion.ca/pw/water/quality/reports/) and their electronic or paper copies may be
obtained upon request by emailing the Region at [email protected] or calling
at 905-791-7800 ext. 4685.
Additionally, the Region of Peel places an ad in the local newspapers to inform its consumers
about the availability of the Water Quality Reports.

3.2 Sampling and Testing
In compliance with the drinking water legislation, drinking water systems are required to monitor
their water quality to ensure it meets provincial standards.
Peel regularly samples and tests raw, treated and distribution system water for a number of
microbiological, chemical and radiological parameters. Peel has always had an extensive water
sampling and monitoring program to better understand the quality of source water, ensure
effective treatment processes, and to diligently monitor and protect the drinking water supply.
Sampling and testing is conducted by trained and qualified operators, who collect water samples
from various sampling sites throughout the Region and immediately test them for first water
safety indicators.
As part of Peel’s water quality monitoring programs, samples are also
collected for laboratory analysis for more than 150 health-related and aesthetic parameters.
The Ministry of the Environment (MOE) requires that all drinking water testing laboratories be
accredited by the Standards Council of Canada (SCC) based on proficiency evaluation conducted
by the Canadian Association for Laboratory Accreditation (CALA) as well as licensed by the
MOE for all drinking water tests performed. All laboratories used by Peel are accredited by the
SCC, licensed by the MOE, and adhere to strict drinking water sample collection, handling and
transport protocols as well as analytical and reporting procedures.
3.3 Certified Water Operators
All water treatment plant, distribution system and maintenance operators and technical staff have
appropriate Water Treatment, Water Distribution and Water Quality Analyst certification, as
required by the Ontario drinking water legislation.
The MOE-mandated training and
certification program ensures that all operators are certified to industry recognized standards.
Peel has established a continuing education program for all staff responsible for operating
drinking water systems. This helps operators to gain knowledge of the latest industry practices,
7
technologies and advanced processes and to effectively maintain system water quality and
quantity.
3.4 Water Quality Notification
In compliance with the regulatory requirements, Peel reports every adverse water quality event to
the Ministry of Health and the Ministry of the Environment and immediately initiates corrective
action to address and resolve the problem and implement control measures to prevent its
recurrence. Peel has established a notification protocol for reporting of adverse water quality
events and makes these reports and data publicly available in the Water Quality Reports. In
2013, there were no events of adverse water quality at the Cheltenham Drinking Water System.
3.5 Water System Inspections
On an annual basis, the Region of Peel drinking water systems undergo the Ministry of the
Environment (MOE) inspection program to confirm compliance with provincial drinking water
legislation.
The MOE’s annual inspection program is an important aspect of drinking water supply to our
consumers. Through this program, the Ministry ensures that Peel meets the sampling, testing and
disinfection requirements, treatment standards, and staff training requirements as stated in the
Ontario Regulations 170/03, 169/03, and 128/04 under the Safe Drinking Water Act, 2002.
MOE inspections provide Peel with an overview of how well our drinking water systems are
doing and how well we meet the province’s stringent regulations. They also provide an
opportunity to review our best management practices and if necessary, implement new processes
to continually improve the operation and management of Peel’s drinking water systems.

4. How well did we do?
4.1 Operation
To protect the health of the public and to ensure consumers receive clean and safe water, the
Ministry of the Environment (MOE) has established the Ontario Drinking Water Quality
Standards (ODWS). These standards are set to ensure water is free of disease causing organisms
and hazardous chemicals.
In 2013, Peel monitored water quality by undertaking tens of
thousands of process samples and tests to ensure a safe and clean water supply. Appendix A
provides a summary of the water quality test results.
Peel is proud to report that for the year 2013, Cheltenham drinking water quality met ODWS.
The MOE performs annual inspections on all municipal drinking water systems. Based on the
inspection findings, the MOE issues score cards. The score is based upon the questions posed by
the Ministry Inspector during each inspection. Cheltenham’s overall performance has been
excellent for the past three (3) inspection years.

5. Drinking Water Quality Programs
5.1 Municipal Drinking Water Licensing Program
Under the Safe Drinking Water Act, 2002 (SDWA) all municipal residential drinking water
system owners in Ontario must have a Municipal Drinking Water Licence (MDWL) to operate
their system. In order to be issued a Licence, the Ministry of the Environment (MOE) requires
owners to have the following five (5) prerequisites:
1. Drinking Water Works Permit (DWWP)
A permit describing the drinking water system and giving authority to establish or alter a
drinking water system. Peel has a valid DWWP for the Cheltenham Drinking Water System.
2. Permit to Take Water (PTTW)
A valid permit to take water issued under the Ontario Water Resources Act (OWRA) specifying
the approved rate of water taking. Peel has a valid PTTW for the Cheltenham wells.
3. An Accepted Operational Plan
The Operational Plan defines and documents the Quality Management System (QMS) for Peel’s
drinking water systems in accordance with the 21 Element requirements of the MOE’s Drinking
Water Quality Management Standard (DWQMS). The Operational Plan outlines the policy
commitments and associated procedures, responsibilities and evaluation measures that ensure
drinking water quality and safety in all processes for water treatment and distribution, from
source to tap.
4. Accredited Operating Authority (Third-Party Audit of the QMS)
Municipal residential drinking water system owners must ensure that their Operating Authorities
are accredited. Peel as the Operating Authority of the South Peel Distribution; Palgrave-Caledon
East; Caledon Village-Alton; Inglewood; and Cheltenham Drinking Water Systems achieved
Full Scope – entire DWQMS Accreditation on August 26, 2011. Full Scope Accreditation
11
recognizes that the Operating Authority has a QMS in place that conforms to the DWQMS as
documented in the Operational Plan. Peel's QMS has been maintained and improved over the
past five (5) years.
In May 2012 the MOE designated two new accreditation bodies under the SDWA. In June 2012
the Region of Peel transferred its accreditation to SAI Global as the third-party auditor for the
purposes of providing accreditation auditing services for a term that extends to August 26, 2014.
5. Financial Plan
Ontario Regulation 453/07 Financial Plans mandates municipal drinking water system owners to
prepare a long term strategy to ensure the financial sustainability of drinking water systems. The
Water Division’s Financial Plan was prepared and approved by Council Resolution in June 2010
and submitted to the Ontario Ministry of Municipal Affairs and Housing (MMAH).
The
Financial Plan at a minimum is required to be updated; approved by Council Resolution; and
submitted to the MMAH every five (5) years prior to an application for renewal of the Municipal
Drinking Water Licence.
Summary of Approvals and Permits
Peel has satisfied all the approvals and permits of the Municipal Drinking Water Licensing
Program and has been operating all municipal drinking water systems under the new DWWPs
and MDWLs since late November 2009. Municipal drinking water licences are valid for five (5)
years. Peel will apply for Licence renewal for each municipal drinking water system in May
2014 to ensure continued authority to operate under the SDWA.

5.2 Source Water Protection
The Clean Water Act, 2006, came into effect on July 3, 2007 with the promulgation of the initial
set of source water protection regulations. The focus of the legislation is to protect existing and
12
future planned municipal sources of drinking water. The source protection process is driven by
locally-based Source Protection Committees that consist of appointed representatives from
municipal, industry, commerce and agricultural sectors and the public at large. The Region of
Peel falls under the jurisdiction of three Source Protection Authorities (SPA) as follows:
•
Credit Valley-Toronto-Central Lake Ontario (CTC) Source Protection Area; most of the
Region of Peel’s groundwater and surface water intakes fall within this SPA
(www.ctcwp.ca) South Georgian Bay Lake Simcoe (SGBLS) Source Protection Area;
only Palgrave Well No. 3 falls within this SPA (www.ourwatershed.ca)
•
Halton-Hamilton (H-H) Source Protection Area; none of the Region’s groundwater
systems or surface water intakes lies within this SPA (www.protectingwater.ca)
Region of Peel has participated in the planning phases of the source protection planning by
carrying out technical studies for assessment reports and policy development through Region of
Peel’s representation on the Source Protection Committees and Working Groups whose work led
to the development of Proposed Source Protection Plans.
Source Protection Plans for H-H, CTC and SGBLS have been recently submitted to the Minister
of Environment for approval. All three plans have significant drinking water threat policies.
There are monitoring and reporting policies for all significant threat policies.
The Region of Peel has an obligation to comply with the Source Protection Plans once approved.
Peel is currently preparing for the implementation of Part IV of the Clean Water Act. One of the
major steps taken by Peel is the appointment of the Risk Management Official and Risk
Management Inspector in 2012. Peel is now working on developing new business processes to
review future development applications in vulnerable areas and perform risk management of
existing significant drinking water threats (SDWTs), as identified through a threats verification
exercise led by Peel in 2012 and 2013. A comprehensive database management, filing and
records keeping system is being developed using internal resources. It is planned for these new
13
business processes to be in place in the first quarter of 2014. Peel has also started to update its
Official Plan to conform to the approved Source Protection Plans by 2015.
For more information on Source Water Protection in Peel, please visit the following link:
http://www.peelregion.ca/pw/water/source-water/need-to-protect.htm
5.3 Private Well Abandonment Program
The Region of Peel implemented a Private Well Abandonment Program for decommissioning of
old, unused private wells within Peel. This work is performed in accordance with the
requirements of the Ontario Regulation 903. The program intends to gradually eliminate
potential pathways of groundwater contamination in areas where groundwater is a source for
drinking water. The program is carried out on a first come, first serve basis, with each well
decommissioning request being evaluated prior to the commencement of any decommissioning
work.
A total of 83 private wells throughout Peel were decommissioned under this program in 2013.
The increase in program participation has grown significantly since 2011. The increase is
attributed to Peel’s efforts toward public awareness through public events, newspaper ads,
mobile road signs, as well as outreach to local real estate firms to help promote the program to
individuals purchasing property in rural areas of Peel.

link: http://www.peelregion.ca/pw/water/water-trtmt/wellhead-abandon.htm
5.4 Watermain Renewal Program
Peel’s overall infrastructure is aging, requiring more investment in preventive and planned
maintenance. In response, Peel has established a comprehensive asset management program
14
which includes the watermain assessment and renewal. The program is an ongoing plan of
upgrading Peel’s linear infrastructure to ensure long term integrity. The program involves repair
or replacement of existing mains to improve water flow, ensure good quality water and upsize if
required to meet future planning needs; all to provide higher level of service to our consumers.
Peel determines priority of watermains replacement based on the following factors:
•
Watermain age
•
Water quality trend
•
Watermain size and material type
•
Watermain breaks and leak history
•
Hydraulic performance of watermain
•
Future municipal and city projects and road re-construction
•
Cost of replacement
The majority of the watermain replacement projects are undertaken in partnership with road and
sewer renewal projects for improved cost effectiveness and minimized public inconvenience.
Using these criteria, Peel plans the watermain renewal program in a financially responsible
manner.
In 2013, 4.59 km of watermains were replaced in the Town of Caledon.
5.5 Community Lead Testing Program
Established in 2007, Peel’s Community Lead Testing Program fulfills the legislative
requirements under the Ontario Regulation 170/03, Schedule 15.1. Based on excellent quality
water test results from the first years of sampling and the amended lead testing legislation,
Cheltenham Drinking Water System has been exempted from collecting plumbing samples and
testing residential and commercial premises for lead.
15
The Region continues to test Cheltenham’s drinking water supply for alkalinity and pH semiannually to ensure water chemistry is being monitored and corrosiveness of water supply system
controlled. As required by the regulation, Cheltenham distribution system is sampled and tested
for lead every three (3) years.
Upon request from the resident, the Region of Peel staff coordinates testing of tap water for lead
at homes that qualify for the program based on the following criteria:
•
homes or buildings built prior to 1960
•
plumbing connected to or suspected to be connected to lead service pipes
•
plumbing made out of or suspected of being made out of lead
The Community Lead Testing Program sampling is conducted semi-annually between the dates
of December 15 to April 15 and June 15 to October 15 each year. Results for 2013 sampling are
summarized in Appendix A of this report. Results of this program also aid in the asset
management and water main renewal program.
For more information on Peel’s Community Lead Testing Program, please contact us at 905-7917800, ext 4685 or visit our website: http://www.peelregion.ca/pw/water/quality/lead-inwater.htm
5.6 Watermain Flushing Program
The Region of Peel’s watermain flushing program is another element of the multi-barrier
approach to ensuring safe drinking water. The primary objective of the watermain flushing
program is to maintain adequate chlorine residuals in the water distribution system. Under the
Safe Drinking Water Act, 2002, Ontario Regulation 170/03 stipulates the acceptable chlorine
residual range. Certified Water Operators measure and record the chlorine residual at each
flush. Flushing is conducted at locations where a low water demand may occur, such as dead-
16
ends and new subdivisions. Flushing frequency is greater in areas where the water demand is
lower. Flushing is also conducted following water system repairs and other situations where a
check of chlorine residual is warranted.
5.7 Watermain Swabbing Program
The objective of the watermain swabbing program is
removal of watermain mineral and residue build up to
improve water quality and restore distribution system
capacity. Swabbing involves inserting a swab (most
commonly used is polyurethane foam) into the main
through a hydrant, and pushing it along the watermain
by water pressure. As the swab passes through the
pipe, it scours the sediment and residue attached to
the watermain, which is later flushed from the system
through the hydrant.
Peel staff diligently assesses the condition of watermains and continuously monitors quality of
water supply. Swabbing program activities are coordinated on basis and frequency dictated by
the monitoring programs and conducted in coordination with the
community residents.
Peel swabbed approximately 3.15 km of watermains in the Town of
Caledon in 2013.
5.8 Hydrant Inspection Program
The Region of Peel hydrant inspection program fulfils a number of
purposes. An annual inspection is necessary to determine the sustained
functionality of each fire hydrant and hydrant branch valve. The
17
flushing part of the inspection also serves to maintain chlorine residual at the hydrant. Fire
hydrant components that are in need of repair are identified during the inspection. Deficiencies
that affect the hydrant’s operability are handled on a priority basis.
Peel inspected 95 hydrants and repaired 10 hydrants in Cheltenham distribution system in 2013.
In 2012, Peel completed the installation of hydrant flow identifiers. These flow
markers are in the shape of a Maltese cross. They are colour coded and designed to let
the fire department know what the available flow is at the hydrant closest to the fire.
The markers are reflective, making them highly visible at night.
5.9 Drinking Water Sampling Station Program
Peel installed a number of drinking water sampling stations throughout
Caledon to improve drinking water quality assessment and monitoring
methods and to improve customer service. Sampling stations are
located at carefully selected points within the distribution system in
Alton, Caledon Village, Caledon East, Mono Mills, Skywood,
Inglewood, Palgrave, Cheltenham and Terra Cotta to ensure the water
samples collected accurately represent the drinking water supplied to
the consumers. The use of sampling stations has reduced the impact on
customers by decreasing the need to enter homes or business facilities
where hours of operation can limit access. In addition to unlimited
access, Water Operations also benefit by having added control over
important sampling conditions such as sample site cleanliness and
security.

Water Safety Indicators Information
 Escherichia coli (E.coli)
Escherichia coli is a fecal coliform and can be detected using approved lab methods. Escherichia
coli is present in fecal matter and prevalent in sewage, but is rapidly destroyed by chlorine. It is a
strong indicator of recent fecal pollution. Presence of E. coli bacteria in a sample of drinking
water signifies potentially inadequate treatment. If E.coli is detected in a sample of drinking
water, corrective action needs to be taken and confirmatory samples collected.
 Total Coliform
Total Coliform bacteria are part of a family of bacteria called Enterics. Coliform bacteria grow
under the same conditions as disease causing bacteria. That allows us to use them as indicator
organisms.
Presence of coliform bacteria in a sample of drinking water signifies inadequate
treatment and is unacceptable. If coliforms are detected, corrective action needs to be taken and
confirmatory samples collected.
 Heterotrophic Plate Count
Heterotrophic plate count (HPC) results give an indication of overall water quality in drinkingwater systems. HPC results are used as a tool for monitoring the overall quality of the water
immediately following treatment and in the distribution system. A HPC result is not an indicator
of water safety but is used as an indicator of water integrity within the water system.
 Disinfection By-products
Disinfection of drinking water is essential to protect the public from waterborne infectious and
parasitic diseases. Disinfection inactivates bacteria in the water and protects the water pipes from
any subsequent contamination during storage or distribution. The most commonly used
disinfectant is chlorine. The use of chlorine may lead to the formation of by-products, including
trihalomethanes (THMs). THMs are formed when organic compounds left in the water after
treatment combine with the chlorine.

Appendix B
FREQUENTLY ASKED QUESTIONS AND ANSWERS ON WATER QUALITY
 Is my water safe to drink?
To protect public health, the Ministry of the Environment has established the Ontario Drinking
Water Quality Standards (ODWS). These standards help ensure that water used by the public is
free from disease-causing organisms, hazardous amounts of toxic chemicals and radioactive
materials.
 Why do we use chlorine?
Chlorine is used to kill bacteria, viruses and other organisms that can cause illness. Ontario
Regulation 170/03 regulates the amount of chlorine that must be added. The regulation states that
we must maintain chlorine residual at a minimum level of 0.05 mg/L and should not exceed a
maximum level of 4.0 mg/L.
 Is the water in Cheltenham hard?
Hardness is typically dissolved calcium and magnesium in water measured as calcium carbonate.
Upon heating, hard water has a tendency to form scale deposits and can form excessive scum
with regular soaps. Conversely, soft water may result in accelerated corrosion of water pipes.
Although Cheltenham water is considered hard it is still acceptable for domestic purposes.
 Should I buy a water softener?
The purchase of a water softener is based mostly on personal preference. Soap suds are formed
more readily with soft water, therefore less detergent is used. The use of a water softener also
reduces the formation of hardness scale in pipes and hot water tanks. Some consumers do not
like the feel of soft water. For example, after rinsing you may still feel a soap film on your skin
if you used soft water.
28
 Why does my kettle get a white film inside?
When water is boiled, calcium and manganese precipitate out of the water and deposits on the
heating element and inner surfaces of the kettle. This does not pose a health risk. The deposit
can be prevented by regular rinsing with vinegar or lemon juice.
 Why does the water sometimes look “cloudy” or “milky”?
Tiny bubbles of air in the water cause the cloudiness. Those bubbles may also cause the water to
appear white or foamy, similar to the appearance of water in a rushing stream. This does not
indicate any problem and clears when the water is left to sit for a few minutes. This is just an
aesthetic not a health concern. If cloudy water does persist, please notify the Region of Peel so
that the matter can be investigated.
 Is fluoride added to my water?
The Region of Peel does not add fluoride to the water in the Cheltenham area. Any fluoride
found in the water is naturally occurring.
 Why does the water sometimes look “rusty”, yellow or tea-like?
Yellow water is a common occurrence. Excessive levels of iron in drinking water may impart a
brownish colour, often seen on laundered clothes, plumbing fixtures, and the water itself.
Running your tap for a few minutes can clear the colour. No health risks are associated with this
discolouration. If you are experiencing problems and your neighbours are not, the hot water tank
or the pipes in your home are likely causing the problem.
 Does the Region of Peel knock on the door to test water or leave a bottle to fill?
Some of our water programs require testing on private premises, such as residential homes or
businesses. This would only be done by Peel with prior arrangements with the owner or tenant of
the premise. Based on the stringent provincial guidelines, drinking water samples must be
collected and handled by qualified persons and analysed at an accredited laboratory; therefore,
29
Peel staff would not leave a bottle at the door requesting a sample of water for testing, and will
always carry a Region of Peel identification card.
There are many responsible home water treatment businesses that offer products that live up to
their claims. Unfortunately, some companies and salespersons resort to grabbing the public’s
attention and misinforming them about the safety of the municipal drinking water supplies in an
effort to sell their products.
To ensure that you are informed about the water quality in Peel and less likely to become a target
of a company trying to sell you costly and inappropriate water treatment equipment, or if you
have questions or concerns, please contact our Water Quality Team at 905-791-7800 ext 4685 or
via e-mail to [email protected]
 Why is lead sometimes present in water?
Lead is a metal substance that can dissolve in water. Traditionally, lead compounds were used in
plumbing fittings and in solder to join pipes together in water distribution systems. If water stays
in a piping system that contains lead for long periods of time, lead may dissolve into the water.
 How does Lead affect my Health?

and Taste
Possible Cause
•
•
•
•
Chlorine getting combined with organics
Chlorination of new water mains
Effects of new plumbing
Change of residency as chlorine concentration
varies from location to location
Suggested Solutions
Chlorine is necessary to control disease-causing organisms.
To minimize the chlorine taste and smell in water;
• Fill a pitcher and let it stand in the refrigerator overnight
• Blend the water for 5 minutes or pour between containers
about 10 times
• Boil the water, let it cool down and then refrigerate
• Home plumbing may be flushed for a minute before water
use (especially in the mornings, after water stands in the
lines overnight)
• The algae are harmless and although the water may not be
aesthetically pleasing, it is safe.
• Clean faucet aerators and screens on frequent basis
• Hot water tanks should be flushed periodically (every 2 to
3 years) to remove rust and scale
• Refrain from flushing solids/organics down the drain;
stagnant wastewater in the drain may generate foul odours
and potentially plug the drain
Musty/Earthy
/Sour/Grassy/
Foul Odour
• Algae that bloom in the lake in the summer
produces a metabolite called ‘geosmin’, which
causes musty/earthy odour
• Dead-end water mains or areas with low water
demand
• Poorly maintained hot water tanks
• Faucet aerators/screens and sink drains
Milky/Cloudy
Water
• Air trapped in water due to water main breaks,
water temperature or pressure change, plumbing
work, construction work in the area, water shutoffs
• Hot water tank temperature may be set too high
• Run all cold water taps at once for a couple of minutes to
flush the lines and release the air
• Lower the hot water tank temperature if above 140F
(60°C)
• Copper in water due to copper plumbing
• Run water for 30 seconds to reduce the effects of local
plumbing (metal concentration) prior to water consumption
• Keep fixtures dry and drip-free

o Hydrant use
o Local Fire
o Dead ends
o Poorly maintained hot water tanks
or
• Originated in hot water tank
• No water use for a longer period of time; return
from vacation
• Flakes are scale caused by hardness
• Faulty or disintegrating hot water tank tubing or
lining
• Pink pigmented bacteria called Serratia
marcescens
• Airborne bacteria; not originating from the water
• Open cold water faucets and flush water for 5 to 10
minutes, until clear
• Refrain from doing laundry to prevent clothes staining
• Hot water tank should be flushed periodically (every 2 to 3
years)
• Run cold and hot water separately to verify the cause; if
hot water is the cause - tank needs a flush
• Open several faucets and flush the water standing in pipes
that may have dissolved pipe scale material
• Can be reduced by frequent cleaning of faucet
aerators/screens and/or frequent flushing of hot water
tanks
• Contact the hot water tank company
• Scrub surfaces with a brush
• Disinfect with a strong bleach solution
• Allow disinfectant to penetrate for 10-20 minutes
• Rinse
