American Molding and Millwork February 2.5, 1987 Page -3- soil being present Is moderate to high. Our preliminary opi ion Is that there Is a fairly high risk of investigative and cleanup costs In the $50,000 to $100,000 range, and moderate risks of incurring clean up costs in the $100,000 to $1,000,000 range. These estimates do not include site remediation costs (approximately $80,000), currently proposed in a J.H. KI infelder Remedial Action Plan, 1986 for areas with identified diesel and penta soil contamination (located near the maintenance building). In order to assess the actual presence of soil or ground water contami- nation (other than Kleinfelder proposed scope of work) and lo further quantify these risks, it will be necessary to complete a Phase II investigation. Analytical screening of soil and water samples will allow for a recommendation as to the potential soil and groundwater contamination liability that this site presents. Cost-effective analytical methods and composlti g of soil samples have been selected for screening purposes with duplicate so'1 samples retained for future, quantified analysis, if necessary. SURFACE SOIL SAMPLING Surface soil and sediment (ditch or drainage trap sediments) samples will be collected at all "areas of interest" except for th underground tank containing primer wash-down water, the penta solution dip tank area (south of Ray Bond Building), and the septic tank area northeast ol the Finger Joint - Building. Soil borings are proposed in these areas and will be discussed later. See Table 1 and 2 for proposed areas of surface soil and sediment sampling. Primary soil samples will be composited and screenec for potential con- taminants as presented in Table 3. All duplicate samples will be Inventoried and stored at the laboratory for future individual chemical analysis, if necessary. No random grid surface soil Samples are proposed for collection at this time as it is our opinion that the areas most likely to be of ected by hazardous materials have been identified during the Phase I "area of interest" investiga- tion. # %kWATFR SAMPLING j -Three water supply wells have been identifie at the facility. However, it is reported by AFP representatives that the facility receives all water from municipal systems. Two'of the wells are located in the southeastern ? portion of the site (east of south storm pond) and do not pear to have been used for some time. The remaining well (west of main emplo(ee parking lot) has f reportedly been used recently (within past year), but can produce water, if needed. To date, no well logs have been located for then wells. It is also not known if adjacent properties rely on groundwater for domestic or industrial needs.
