CA 95151-9027 <br /> RE: OSP; SITE CODE: 2287 <br /> 8715 W. GRANTLINE ROAD; TRACY <br /> _ The recent report submitted by Clayton Environment4,:43nc,� For Orchard supply <br /> Hardware recommends additional soil borings be dri.l •irrand around the recently <br /> replaced Monitoring Well 33. The soil contamination documented during the <br /> drilling of the monitoring well 38 at depths of 4 feet and 9 feet indicated the <br /> presence of heavy petroleum products, ail and grease, The water sampling <br /> collected from the monitoring well 38 did not detect contaminates exceeding MCL's <br /> (maximum contaminate levels). <br /> we agree that additional soil borings would benefit the overall site,s definition <br /> and help to determine, the need for additional soil removal or whether long-term <br /> groundwater monitoring would best suit this site. <br /> in telephone conversation between Clayton Environmental, Inc. and a member of <br /> my staff, various laboratory analyses were discussed which may <br /> determination of the oil and grease Y provide for better <br /> 5 (i.e., 418.9 or 5520, formerly known as 503).. <br /> The selection of the analysis should be one that would provide solubility <br /> results (waste Extraction Test, Title 22) rather than analyses which vary in <br /> 1 detection limits and.also vary in quantitative results (both methods for oil and <br /> i grease have interferences which may mask tate presence of volatile <br /> .. constituents). <br /> j + In addition, the check #53791 issued 12/10/90 for the septic and well destruction <br /> 8 <br /> tom,; for the neighboring parcel, address 8885 W. Grantline Road, will be returned to <br /> Clayton Environmental, Inc. The amount of .;heck 053791 exceeded the amount due. <br /> Clayton Environmental will arrange for a new check in the amount of.
