Source Removal Report/Site Rehabilitation Completion Report (SRR/SRCR)
City of Sarasota Marian Anderson Place
Sarasota, Florida
COM_130525
BF280401000
--------------------------------------------------------------------------------------------------------The Florida Department of Environmental Protection (Department) has completed our technical
review of the Source Removal Report/Site Rehabilitation Completion Report (SRR/SRCR) for the
City of Sarasota Marian Anderson Place. The report was generated by Leggette, Brashears & Graham,
Inc. (LBG), and received by the South District on October 22, 2014. Groundwater monitoring at the
property was initiated following the discovery of an unregulated landfill that had been active from the
1940s through the 1960s.
In a Pilot Test Plan (PTP) dated May 8, 2013, LBG proposed the excavation of a series of test-pits in
the vicinity of MW-12R; which has historically had the highest concentrations of Arsenic. The testpits were proposed to investigate the subsurface conditions for a potential source of the Arsenic
detected within the groundwater. Although no potential source of Arsenic was identified during the
excavation of the test-pits, beneath the uneven surface cover of grasses and organic soil, personnel did
note a layer of rusted metal, composed primarily of discarded iron, ranging in thickness from 0.1 to
0.2 feet at an average depth of 2.0 feet below surface grade, overlying a 1.5 to 2.0 foot layer of loose
soils and sands. Beneath the loose material, a deposit of various sized glass bottles, approximately 4.0
to 7.0 feet in vertical thickness was encountered. It is speculated that the glass originated from a
former glass works plant in the general north Sarasota area, and returned or rejected bottles to the plant
were disposed on the property. Beneath the glass, LBG encountered a layer of un-cemented and
cemented coquina, over a consolidated coquina and lime rock layer. LBG also proposed a well-point
dewatering system surrounding MW-12R in an attempt to determine the feasibility of a groundwater
extraction system as a means of reducing the existing Arsenic concentrations within the groundwater
at this site.
On May 29, 2013, LBG supervised the excavation of eleven (11) test-pits to an approximate depth of
10 feet below land surface (bls). The approximate depth to water was determined to be 5.75 feet bls.
A total of five (5) soil samples were collected from four (4) of the test-pits (TP-21, TP-23, TP-2N, and
.

TP-1W) at approximately 2 to 3 feet bls. The collected samples were submitted for laboratory
analysis by EPA Method 6010 for Total Arsenic.
The laboratory analytical data reported Arsenic at 4.4 milligrams per kilogram (mg/kg) in TP-23 at 3.0
feet bls, 10 mg/kg in TP-21 at 3.0 feet bls, 8 mg/kg in TP-21 at 2.0 feet bls, 6.3 mg/kg in TP-2N at 2.0
feet bls, and 8.1 mg/kg in TP-1W at 2.0 feet bls. All of these concentrations exceed the Florida
Administrative Code (F.A.C.) Rule 62-777 Soil Cleanup Target Level (SCTL) for Residential Direct
Exposure of 2.1 mg/kg.
The well-point system was installed in late-May 2013, and pumping was initiated on June 3, 2013.
The initial results indicated that, due to the “tight” soil formation and the ineffective shell-rock filter
packs, the well-point system would not be an effective means of dewatering this site because a
reasonable groundwater extraction rate could not be achieved. In a June 7, 2013, amendment to the
PTP, LGB proposed the excavation of a series of sump-pits and Kelly trenches. The amendment was
approved by the Department via email on June 7, 2013.
Between June 2013 and December 2013, LBG personnel supervised the excavation of four (4) sumppits and two (2) trenches. Each pit, measuring approximately 25 feet by 25 feet, was excavated to an
approximate depth of 10 to 12 feet bls. Reciprocating diaphragm pump and hose systems provided by
the City of Sarasota Department of Engineering were utilized to extract the accumulated groundwater
from each pit.
In December 2013, two (2) trench-pits were excavated in the vicinity of sump-pits #12R and #20. The
trench-pits were connected to the adjacent sump pit location #12R and #20, respectively, to eliminate
the need for additional pump systems to extract water.
In April 2014, LBG proposed expanding sump-pit #12R to an area that encompassed a 50-foot radius
around the former groundwater monitoring well MW-12R. The LBG proposal was approved by the
Department in a letter dated April 25, 2014.
Groundwater samples were collected by LBG personnel from groundwater monitoring wells and from
the sump-pits in 2013 on June 14, 19, and 27, July 3, 9, 16, 23, and 31, August 5, 13, and 27,
September 11 and 19, October 30, November 15, and December 5, and 17; and in 2014 on January 8
and 21, February 4 and 19, March 5 and 19, April 3 and 28, May 16, June 3 and 20, July 3, 22, and 29,
August 12 and 28, September 10 and 26, and October 9. All of the collected samples were submitted
for laboratory analysis by EPA Method 6010 for Total Arsenic.
The initial Arsenic concentrations from a sampling event conducted in October 2012 were reported as
18 micrograms per liter (µg/l) in MW-1R, 14 µg/l in MW-11, 90 µg/l in MW-12R, 39 µg/l in MW-17,
and 11 µg/l in MW-20. All of these concentrations exceed the F.A.C. Rule 62-777 Groundwater
Cleanup Target Level (GCTL) of 10 µg/l. The only GCTL exceedances reported in the October 9,
2014 sampling event were from MW-17 (12 µg/l) and Sump-pit #1R (12 µg/l). A declining

concentration trend can be observed throughout the groundwater extraction activities. Furthermore, no
“rebounding” of Arsenic concentrations has been noted since the cessation of groundwater pumping in
August 2014.
The excavation of the eleven (11) test-pits did not reveal any material that could serve as a potential
source of the elevated Arsenic concentrations within the soil and groundwater at this site. However,
extensive research has indicated that naturally-occurring Arsenic is commonly found within limestone.
In addition, Arsenic is strongly attracted to oxides of Iron, Aluminum, and Manganese. As such, the
layer of rusted metal debris noted within the test-pits would act as a “sink” for the naturally occurring
Arsenic in the soils surrounding it. Furthermore, as the metal layer oxidized, the Arsenic would tend
to follow the oxides leaching into the groundwater; thereby inflating the concentrations of naturallyoccurring Arsenic in the groundwater in this area. This theory is supported by the recorded Arsenic
concentrations at sites within a close proximity to the subject site. The groundwater samples collected
at the Robert L. Taylor Community Center (COM_307173), which is located approximately ½ mile to
the west of the subject site, had an average Arsenic concentration of 15.4 µg/l in 2012. The
groundwater samples collected from the Former Leroy Sims property (COM_69397), located
approximately ½ mile northwest of the subject site, had an average Arsenic concentration of 24.5 µg/l
in 2012. The groundwater samples collected from Booker High School, located approximately ¾ mile
west of the subject site, had an average Arsenic concentration of 31.31 µg/l in 2012. No potential
anthropogenic source of Arsenic was located at any of these sites. In fact, when assessing the Leroy
Sims site, the Site Investigation Section (SIS) of the Department concluded that “The Arsenic found in
this area is very likely not anthropogenic in origin but is naturally occurring.”
Summary:
The Florida Department of Environmental Protection (Department) has completed our technical
review of the Source Removal Report/Site Rehabilitation Completion Report (SRR/SRCR) for the
City of Sarasota Marian Anderson Place and concurs with the environmental consultant that the
identified Arsenic impacts at this facility have been adequately remediated pursuant to Chapter 62-780
F.A.C. Contamination Site Cleanup Criteria and that any Arsenic concentrations within the soil and/or
groundwater at this site that exceed their respective Cleanup Target Levels (CTLs) are naturallyoccurring and do not reflect an anthropogenic source.
A Site Rehabilitation Completion Approval (SRCA) is appropriate, and No Further Action (NFA)
pursuant to Chapter 62-780.680(1) Florida Administrative Code (F.A.C.) Risk Management Options
Level I (RMO I) status is approved for the City of Sarasota Marian Anderson Place (Waste Cleanup
Tracking Number: COM_130525/Brownfield Site ID: BF580401000).
Upon receipt of the No Further Action (NFA) approval letter, the responsible party shall properly
abandon all groundwater monitoring wells and any piezometers associated to the assessment and
remediation pursuant to South Florida Water Management District (SFWMD) guidelines.
