Subject: Sapp Battery NPL Site Soil Acidity, Total and Leachable Metals Testing Report - Revision 0
L Introduction Black & Veatch personnel, under the direction of the EPA Region 4 Response Action Contract
(RAC) II, Task Order 005-RDRD-0417, collected soil and groundwater samples from the Sapp
Battery NPL Site in Cottondale, Jackson County, Florida in October 2009. Black & Veatch, with
consent from EPA, subcontracted Shaw Environmental Inc.'s (Shaw) Technology Development
Laboratory (TDL) in Knoxville, Tennessee to perfonn a bench-scale treatability study on these
samples to determine the metals content, acidity of various soil sediments, and to determine tiie
amount of reagent needed to raise the groundwater pH to levels between 8 and 9 Standard Units
(SUs). Raising die pH in the groundwater at the Site is under consideration as a remedial altemative
to reduce the metals concentrations in the groundwater. This testing report provides the data and
evaluation for the bench-scale treatability study performed by Shaw's TDL.
//. Sample Description Thirty-five samples of soil and groundwater were received at Shaw's TDL from the Sapp Site
between October 12 and October 20, 2009. Attachment 1 provides the traffic report of receipt
dates and sample identifications. The testing ofthe samples was put on hold by EPA in February
2010. The samples were archived and stored until EPA decided to proceed with testing, which
happened in August 2010. Several of the original proposed analyses were eliminated at the
request of the EPA. Consequently, only eight of the 35 samples were tested. The samples
selected for analyses were chosen based on the lead concentrations detected in the groundwater
at these locations across the Site. The remaining sample materials not tested are being disposed
of by Shaw's TDL in accordance with all applicable regulations.
Two subsurface soil samples, SBEW30 collected at 32 feet below land surface (ft bis) and SBEW32
collected at 30 ft bis were analyzed for total lead; the remaining six soil samples were analyzed for
the following:

The same samples were analyzed for SPLP and the results are presented in Table 3. For
leachability to groundwater, lead is the primary COC and has an EPA maximum contaminant
level (MCL) and a Florida groundwater CTL (GCTL) of 0.015 milligrams per liter (mg/L). As
seen from Table 3, all analyzed SPLP lead concentrations were less than the MCL/GCTL at
<0.011 mg/L. Three samples, TS01_SB04, TS01_SB02, and SBOl had SPLP leachate
concentrations for aluminum greater than the GCTL. Sample TS01_SB_02 also leached iron and
manganese in concentrations greater than their respective GCTLs. These three GCTL values are
secondary EPA MCLs. That means, they are based on aesthetic considerations and are not
human health-based. The soil samples with the highest total aluminum, iron and manganese

concentrations (TS01_SB04, TS01_SB02) also leached SPLP concentrations in exceedance of
the secondary MCLs. Sample SBOl was different from all other samples investigated. All the
other samples tested had acidic SPLP leachates ranging in pH from 4.1 to 5.2 SUs; however,
SBOl had a more alkaline leachate pH value of 7.8 SUs. This sample was composited from two
white loose fine-grain sand lenses in the boring; indicative of a limestone sediment interval. In
summary, all the soil samples analyzed were below their respective FDEP commercial/industrial
SCTL and leached lead at less than the primary MCL/GCTL. Three samples leached aluminum
and one sample leached iron and manganese above their respective MCL/ secondary GCTL.

In addition to chemical testing, bench-scale treatability testing was performed on the samples to
determine the amount of alkaline reagent that would be required to raise the groundwater pH to 8
or 9 SUs. Data show that at locations at the Site where there are naturally occurring limestone
deposits, the groundwater in these areas is alkaline, e.g., pH ranges from >7 to about >8.5 SUs
and metals concentrations are reduced. A previous remedial alternative considered for the
groundwater remedy at the Site was to extract higher pH groundwater (e.g., groundwater in

contact with limestone in the Floridan aquifer) and inject into the more acidic groundwater in the
intermediate aquifer zones at the Site. Based on these observations, a remedial option under
consideration is to limit the mobility of soluble lead and other metals by injecting an alkaline
solution to raise the groundwater pH. Table 4 shows the results ofthe bench-scale titration tests.
The soil samples were mixed with Site groundwater at 50 grams of soil in 50 grams of
groundwater. The resultant pH was recorded. As seen in Table 4, all soil pH values, except for
SBOl, were acidic (pH 4.0 to 5.1 SUs). The soil-groundwater pH values were similar to the
SPLP pH values.

Titrations were conducted to estimate the amount of alkaline reagent in groundwater that would
need to be added to the acidic site soil to raise the pH to values between 8 and 9 SUs. Each soil
sample was titrated using a sodium hydroxide (NaOH) solution. The equivalent quantity of
calcium carbonate (CaCOs) addition was calculated for each NaOH addition. Table 4 presents
the "milliequivalents (meq) of NaOH per kilogram (kg) of soil" and the equivalent "pounds (lbs.)
CaCOs per ton of soil" needed to increase the soil pH to either 8 or 9 SUs. The meq NaOH/ kg
of soil ranged from 0.00 to 38.4, which equates to a range between 0.10 to 3.85 Ibs./ton of
CaCOs needed to increase the pH to 8 to 9 SUs. The bench-scale study titration curves are
shown as Figures lA/B - 6A/B.
