KL EINFFLUER <br /> 7 CONCLUSIONS AND RECOMMENDATIONS <br /> Between .lune I I and 18. 1999 disposal sites B and C were excavated. Soil and groundwater <br /> samples were collected within the excavations and analyzed for selected analytes listed in <br /> Section 5. On July 14. 1999 three of- six monitoring wells were abandoned in the vicinity of <br /> these two disposal sites. "Three of the wells were not able to be located. The work was <br /> conducted in southeast portion cit'ibe former Spreckels site located in Manteca. California (see <br /> Plate 3). Based upon Kleinfelder-s observations and the reported analytical results Kleinfelder <br /> formulated the following Cunrlusiuns and recommendations: <br /> 7.1 CONCLUSIONS <br /> 1) Review of the analytical results. of three soil and two groundwater samples analyzed at <br /> Disposal Sites B and C. show that reported levels were either non detect at or above <br /> laboratory reporting limits ill- were below the regulated levels and I'RGs summarized on <br /> Table I under the "Tables Tiibi ol'this report. <br /> 2) Verbal authorization was �,ivcn by Robert McColIum of the PHS/EI-ID that backfilling of <br /> Disposal Sites B an([ C be conducted on.luly 16. 1999. <br /> 3) The debris material at the two disposal sites(B and C) appeared to be removed. <br /> 4) Debris removed from the iwo disposal areas were inoved to constrnCuon debris stockpiles on <br /> site for later disposal or reevclin�,. <br /> 5) The slaked lime and lime malcrial from Disposal Site B was Mulled to the lime ponds [all the <br /> lime in the lime ponds will he handled in accordance with the Waste Discharge Requirements <br /> (WDRs) # 97-204 for the lime porids.l. <br /> 6) Three of six monitoring wells NIW-7. MW-9 and MW-1 I surrounding the Disposal Areas B <br /> and C. were successfully drilled out and grouted to the surface in accordance with the <br /> P1-IS/El-I1) abandonment permit. The remaining three monitoring; wells MW-S, MW-10 and <br /> M` -12 were unable to be Ideated and were likely destroyed during prading activities at the <br /> sitz. <br /> 20-±978-11:.W3612019766 llgec 17 ot'20 <br /> 0 1999.
