4 <br /> begins. It is quite possible that me systcm designed and <br /> funded by all responsible parties would be more efficient, <br /> both technically and Financially, than several .-narac� <br /> Systems. <br /> 2. Soil excavation is not deemed necessary due to the site being <br /> paved and the low seasonal fluctuations of groundwater 'table <br /> levels beneath the site. <br /> 3. A regular groundwater monitoring program should be imple- <br /> mented during 1987. This monitoring would include monthly <br /> j water-level measurements anduarterl <br /> q y groundwater sampling <br /> and analysis for benezene, toluene, xylene, and fuel hydro- <br /> carbons. The results of the monitoring will be used to <br /> calculate monthly groundwater flow directions and gradients <br /> and water table fluctuations beneath the Geweke site. Hydro- <br /> carbon concentrations will be compared with flow directions <br /> to evaluate potential direction of contaminated groundwater <br /> flow. <br /> 4. All involved regulatory agencies shoul,". be notified of these <br /> recommendations. A meeting to d.scuss the proposed plan (s) <br /> of action should be called between Geweke Properties and the <br /> agencies. <br /> 5. Data exchange, between the regulatory agencies, Gesieke <br /> Properties' %,onsultant, and Beacon's consultant should be <br /> established and maintained. As the problem appears to <br /> be regional in scope, communication between potential <br /> responsible 'parties will provide valuable additional data <br /> and ideas. <br />
