The proposed sampling scheme will be definitive, in accordance with the Guidance for Performing Site Inspections Under CERCLA. OSWER Directive
#9345.1-05, September 1992, and "Removal Program Representative Sampling Guidance, Volume 1: Soil, OSWER Directive 9360.4-10, November
1991. Groundwater samples will be collected from pre-selected wells for laboratory analysis. See Appendices 1 and 2 for additional site-specific
information and site location maps.
Three 2-inch diameter monitoring wells were installed within the tetrachloroethene (PCE) plume identified by a 1987 soil gas survey conducted by Ecology and Environment, Incorporated. Tetra Tech STAR Twill deploy passive diffusion bag (PDB) samplers in each monitoring well (see Appendix
1 ). The PDB samplers will be centered within the saturated screened interval of each monitoring well and will be allowed to equilibrate for a minimum
of 14 days before they are retrieved for sampling. After the PDB samples have been collected, each monitoring well will also be sampled for VOCs
using disposable bailers. Data from both sample collection methods will be compared upon receipt of the laboratory data. Tetra Tech START will also collect groundwater samples from Municipal Wells #6 and #7 (from spigots near the wellheads) directly into the
appropriate sample containers.
All samples will be will be collected in two, 40-milliliter (mL) vials and submitted to the Region 7 EPA laboratory in Kansas City, Kansas, for analysis
of volatile organic compounds.

• Field QC Samples: For this investigation, field QC samples will consist of trip blanks, field blanks, and duplicate samples. One trip bhi.nk
(water) will be prepared per sampling event. The trip blank will be prepared by Region 7 EPA Laboratory personnel. The trip blank will be used to determine whether any VOCs were introduced during transportation of the samples/containers. One field blank per sampling event will be prepared by the START sampling team using high-purity water supplied by the Region 7 EPA Laboratory. ·The field blank will be used
to assess contamination of sample containers and preservatives used for the project. Finally, three duplicate groundwater samples will be
collected during each sampling event. One duplicate will be collected from a monitoring well using the PDB sample collection method. The second duplicate will be collected from a monitoring well using a disposable bailer, and the third duplicate will be collected from one of the municipal wells. The duplicate samples will be collected to assess total method precision .. All QC samples will be submitted for the analyses listed in the attached tables. Criteria for evaluation of blank samples are dependent on the levels of contamination found in environmental samples to determine whether the environmental samples are representative. Duplicate results will be evaluated based on criteria established for the associated analytical methods to determine the overall precision of the sampling data. Analytical results of all QC samples will be
evaluated by the EPA project manager and EPA contractor(s) to determine the usability of the data.

1.0 INTRODUCTION
The City of Atlantic is located in Cass County, Iowa, approximately 7 5 miles west of Des Moines, Iowa,
and 45 miles northeast of Council BlUffs Iowa (Appendix 2, Figure 1). Tetrachloroethene (also called
perchloroethene or PCE) was detected in Atlantic Municipal Utilities (AMU) Public Water Supply (PWS)
Well #7 during a water quality survey conducted by the Iowa Department ofNatural Resources (IDNR)
in 1982 (Appendix 2, Figure 2). Subsequent sampling events through the 1980's and 1990's detected PCE
in Well #7 at concentrations ranging from 11 micrograms per liter (Jlg/L) in March 1995 to 260 Jlg/L in
August 1984. Since August 1982, water from Well #7 has been pumped to either Buttermilk Creek or to
the City of Atlantic's wastewater treatment system in an attempt to restrict the migration of the PCE
contamination to other nearby drinking water supply wells.
In August 1987, Ecology & Environment, Inc., under contract to the U.S. Environmental Protection
Agency (EPA), delineated the approximate extent ofPCE contamination by conducting a soil gas survey.
The survey suggested the source area was just south of 7th Street and east ofPlum Street (Appendix 2,
Figure 2). The area is now occupied by a Burger King restaurant and a building occupied by Rolling Hills
Bank and Trust. The report also stated that a former dry cleaning business (pre-1960) was located in the
area of highest PCE concentrations detected in the soil gas samples (i.e., the suspected source area).
In 1998, IDNR conducted a fo~low-up investigation of the PCE contamination to better defme the source.
The report concluded that the primary source ofPCE contamination appeared to be the location of the
former dry cleaning business, now owned by the Rolling Hills Bank and Trust (Appendix 2, Figure 2).
The report also recommended that monitoring wells be installed to better defme the extent of PCE
contamination in groundwater near the suspected source area.
In 2002, Tetra Tech START conducted activities to better defme the limits of the soil contamination in the
previously identified source area and to obtain groundwater quality data in the immediate vicinity of the
source area. Three 2-inch diameter monitoring wells were installed within the PCE plume identified by
the 1987 soil gas survey, and thirteen Geoprobe soil borings were collected in the suspected source area
currently occupied by Burger King, the Rolling Hills Bank and Trust, and the American Security Control
buildings (Appendix 2, Figure 3).
G9011/0116 1·
2.0 PROPOSED FIELD ACTIVITIES
Tetra Tech START will collect groundwater samples from Municipal Wells #6 and #7 (Appendix 2,
Figure 2) and from each of the three aforementioned monitoring wells (Appendix 2, Figure 3) in April and
July 2003 for analysis of volatile organic compounds (VOCs).
Tetra Tech START will deploy passive diffusion bag (PDB) samplers in each of the three monitoring
wells. The PDB samplers will be installed in the center of the saturated screened interval of each
monitoring well, in accordance with the User's Guide for Polyethylene-Based Passive Diffosion Bag -
Samplers to Obtain Volatile Organic Compound Concentrations in Wells, Part 1: Deployment,
Recovery, Data Interpretation, and Quality Control and Assurance (U.S. Geological Survey Water
Resources Investigations Report 01-4060). In accordance with this document, the PDB samplers will
be allowed to equilibrate for a minimum of 14 days before they are retrieved for sampling.
After the PDB samples have been collected, each monitoring well will also be sampled using a disposable
bailer. Three well volumes will be purged from each well, and field parameters (pH, conductivity,
temperature, turbidity) will be measured to ensure that stabilization has been achieved prior to sample
collection.
When sampling the municipal wells, Tetra Tech START will collect groundwater samples from spigots
near the wellheads directly into the appropriate sample containers.
All groundwater samples will be will be collected in two, 40-milliliter (mL) vials, preserved with
hydrochloric acid to a pH <2, and stored in iced coolers. The samples will be shipped or hand delivered to
the Region 7 EPA laboratory in Kansas City, Kansas, for analysis of VOCs.
