Page 2 <br />April 18, 1995 <br />• stem auger drilling methods. Based upon drilling conditions it seems reasonable to <br />assume 10 to 15 shallow soil borings can be completed in one field day. Upon <br />completion of all drilling and sampling, the boreholes will be abandoned pursuant to <br />MDH well codes. <br />Representative soil/groundwater samples from the boreholes will be selected for <br />laboratory confirmation analysis based upon soil characterization data including visual <br />staining, odors and jar headspace results. 5oi1 samples are proposed to undergo diesel <br />range organics (DRO) and lead analysis while groundwater samples are proposed to be <br />analyzed for VOCs and lead. A total of eight soil and six groundwater samples are <br />estimated. Some boreholes may require no analysis to be performed while other <br />boreholes may require two samples in order to characterize impacts at depth. <br />Groundwater samples will be collected in such a manner ±a assess water quality for the <br />entire property. As previously mentioned, a representative soil sample is also proposed <br />to undergo TCLP analysis for hazardous material determination. Remaining soil samples <br />will be frozen under proper chain of custody documentation for future analysis, if <br />necessary. <br />Upon receipt of laboratory results and compilation of data a draft summary report will <br />be prepared for your review prior to issuance of the final copy. The report will include <br />• soil boring data, field observations, chemical results, and a discussion of findings with <br />recommendations for additional work, if necessary. <br />Steve, an opinion of expected costs to complete the work outlined above is attached for <br />your use. Should you have any questions or concerns, please do not hesitate to call. <br />Thank you. <br />maw:memo41895.wp/GO <br />• <br />B.A. LIESCH ASSOCIATES, INC. 13400 15TH AVENUE NORTH MINNEAPOLIS, MINNESOTA 55441 <br />
