Re: Former Koppers Company, Inc.Newport Site (Newport, Delaware)BBL Project #: 388.27.007

Dear Mr. Mellon:

On behalf of Beazer East, Inc. (Beazer) and E.I. du Pont de Nemours and Company (DuPont), Blasland,Bouck & Lee, Inc. (BBL) conducted subsurface field activities at the Former Koppers Company. Inc. sitelocated in Newport, Delaware between December 2, 2002 and December 13, 2002. Except as noted inthis report, field activities were conducted in accordance with the Scope of Work for Delineation of theLower Fine-Grained Unit and Vertical Extent of NAPL, and the Addendum to Scope of Work forDelineation of the Lower Fine-Grained Unit and Vertical Extent of NAPL, that were approved by theUnited States Environmental Protection Agency (EPA) by letter dated October 21, 2002. Data obtainedfrom this investigation will be incorporated with other Site data into the Feasibility Study for the Site.

The purpose of the subsurface field work was to confirm the presence of a fine-grained, low-permeabilityunit within or near the top of the Potomac Formation and to confirm the vertical extent of nonaqueousphase liquid (NAPL). The soil boring results will be used to further evaluate the ability of the fine-grainedunit to prevent the vertical migration of NAPL and act as a confining unit. Two monitoring wells alsowere installed during field activities on the west side of the Fire Pond. Information from these twomonitoring wells will be used to better understand potential NAPL migration, and will be used in thedevelopment and evaluation of remedial alternatives in the Feasibility Study for the Site. Figure 1 showsthe locations of the borings performed and monitoring wells installed as part of this field effort. Geologiclogs, monitoring well construction details, and geotechnical laboratory data are provided as attachments.

A summary of borings and monitoring wells installed as part of this field effort, including location,rationale for installation, total depth, and depth to low-permeability layer, is attached as Table 1. Thelow-permeability layer was encountered at all boring locations except for SB702 and SB709, which wereterminated before encountering the fine-grained unit because of the presence of NAPL. NAPL wasobserved in 10 of the 17 boring and monitoring well locations. Where detected, the appearance of theNAPL was consistent with prior observations. Generally, the NAPL was present as a black organic

material with a creosote-like odor. In the top two feet of surficial soils, NAPL was present as a hard, dry,and brittle material that was more solid than liquid. In subsurface soils, the NAPL was present in thin,small seams (or stringers) and blebs (or nodules) at some locations, and appeared to saturate the soil poresat other locations.

Table 2 provides a summary of geotechnical laboratory data for samples of the low-permeability layer.As shown, the vertical hydraulic conductivity of the fine grained unit samples ranged from 1.13xlO"s to3.01xlO~7 centimeters per second (cm/s). The clay fraction for those samples ranged from 12 to 48percent, with an average of 28.3 percent clay. The silt fraction of the fine-grained unit samples rangedfrom 15.6 to 50.8 percent, with an average of 34.4 percent silt. Based on the Atterberg Limits of soilsamples with less than 50% retained on the #200 sieve, and according to the Unified Soil ClassificationSystem (USCS), the soil classifications for these samples ranges from "silt with sand" (SM) to "sandylean clay" (CL).

Minor deviations from the Scope of Work are noted below.

• The Work Plan stated, "Borings will be considered completed when the vertical extent of NAPLis observed and when at least 2 feet of the lower fine-grained unit is observed." However, SB702and SB709 were terminated prematurely to prevent drag-down of existing NAPL in the boring.The low-permeability layer was 1-foot or less in thickness when encountered at boring locationsSB701,SB705,andSB710.

• As shown on Figure 1, six borings (SB706-SB71 1) were drilled in the Process Area. BoringsSB707 through SB709 did not extend to 30 feet below ground surface (bgs) as specified in theWork Plan because the low-permeability layer was encountered at 23 and 24 feet below groundsurface (bgs), respectively. Therefore, these borings were terminated after sampling the fine-grained layer. Boring SB709 was terminated at 20 feet bgs due to the presence of NAPL.

• The low-permeability layer was encountered at 13.5 feet bgs in SB703, located in the K Area.Therefore, the boring was terminated at 16 feet bgs, where an undisturbed sample was taken.

• Boring SB701 located in the South Ponds Area, was drilled deeper than specified in the WorkPlan. The low-permeability layer was encountered at 33 feet bgs; the boring was terminated at 38feet bgs.

• Boring SB702 was terminated at 16 feet bgs, prior to encountering the low-permeability layer,due to the presence of NAPL in the boring.

Please contact me with any questions.

Sincerely,
