PES Environmental, Inc. <br /> `tr. Jeff Werner <br /> Februmv 12, 1991 <br /> Page 9 <br /> about $30,000 and carbon may not prove to be cost-effective when compared to <br /> k biotreatment and chemical oxidation. Dierefore, although treatment of the <br /> . groundwater by carbon adsorption may app= to be promising based on a preliminary <br /> screening, a detailed evaluation is necessary to provide a more reps'entative cost <br /> analysis. <br /> Task , pnrroretatian and Reporting <br /> `R After the results have been obtained from all sail and groundwater sample analyses, PES will <br /> summarize the data and information obtained during the investigation in a report. In <br /> addition, PES will summarize the results of our detailed evaluation of the interim <br /> groundwater extraction, treatment, and disposal system. As a minimum, the report will <br /> contain: <br /> Litholagic logs graphically depicting the encountered subsurface soil types and the <br /> well completion details for�~-r h borehole: <br /> w <br /> • Tabulation and graphical illustration of groundwater chemical analysis results, € <br /> including copies of the original laboratory reports and chain of custody records; <br /> r Tabulation and graphical representation of groundwater elevation data: <br /> An assessment of the lateral extent of petroleum hydrocarbon•affected groundwater; <br /> and <br /> l Preliminary design of the proposed groundwater extraction, treatmem, and disposal <br /> system. <br /> SCHEDULE <br /> The project schedule is presented in Table 2, Assuming the availability of suitable drill rigs <br /> and no significant delays in negotiating access agreements and in obtaining data on nearby <br /> properties, the field work should begin within four weeks following approval of the work <br /> pla., and issuance of monitoring well and encroachment permits. The site investigation <br /> report ''ncluding our proposed design of an interim groundwater extraction, treatment and <br /> I� disposal system will be submitted Po the appropriate regulatory agencies within eight weeks <br /> following completion of field.work. As previously mentioned, the time required to obtain a <br /> {' <br /> NPDES permit controls wizen operation of an interim groundwater treatment is possible. <br /> PES appreciates the opportunity to be of service to Geweke Land Development and <br /> r comments on this work plan. <br /> Marketing.
