16 August 2001 AGE-NC Project No, 01-0852 Page 2of7 - • Potential for release of contaminants to evaporation ponds on the southern portion of the subject property; • Potential release of hexavalent chromium from cooling towers formerly on site. 1 AGE recommended by letter dated 26 July 2001 collection and analysis of soil samples in the areas of the above noted potential environmental concerns to assess for suspected contaminants. In addition, AGE had recommending sampling the water wells on and serving the site for potential mobile contaminants and conducting a magnetometer survey for a possible third UST in the approximate area identified as its location. This assessment addressed the areas of known potential soil contamination due to operation of the former distillation unit.and did not address ground water or attempt to locate and assess the reported third UST. 2.0. PROCEDURES Soil samples were collected from areas of potential concern on 01 August and 06 August 2001 utilizing a backhoe to trench or pothole in the desired sampling localities. Sampling localities were selected based on known sump, new pond, old pond, cooling tower and AST locations. Sampling localities in the former distillation unit and suspected former sump areas were inferred. from photographs. Access limitations and/or subsurface obstacles prevented close in sampling for the active sump (T7) and in the area of a former AST near the southeast corner of the former fermentation room building (T9). At the request of Copper Enterprises., Inc., all samples were acquired utilizing a backhoe. The baQkhoe and operator,provided by Copper Enterprises, Ino;,were utilized to excavate to the target sampling depths in each sampling locality,and to obtain a scope of soil to collect,a soil sample. Soil ' samples were collected into 2-inch by 6-inch or 3-inch stainless steel and brass sampling sleeves. A metric soil sampler equipped with a slide hammer was utilized to drive the sampling sleeve into the less disturbed soil behind the bucket cutting edge on 06 August 2001,but difficulties with the sampler obligated hand pushing or packing the sleeves during the 01 August 2001 sampling event. The sleeves were packed full of soil to minimize head space, the ends were covered with Teflon sheets and then sealed with a plastic end cap and duct tape. Each sleeve was then labeled with the sample identification,collection date and time and with the sample collectors initials.The preserved sample was' then stored in a chilled container pending shipment to a DHS-certified analytical laboratory under chain of custody for analysis for identified potential.contaminants. Selected soil samples collected in the vicinity of the cooling towers were analyzed for hexavalent chromium by EPA Method 7196A; selected samples collected in the general vicinities of all former Advanced GeoEnrironmental,Inc.
