i <br /> 5.0 CONCLUSIONS & RECOMMENDATIONS <br /> Groundwater at this site remains contaminated, and the monitonng program should be <br /> continued GeoAudit recommends that the next quarterly monitoring event be conducted <br /> in April 1994 <br /> As discussed in section 2 0, PHS/EHD has requested additional field work at the site. <br /> GeoAudit recommends that approximately 100 gallons of water be removed from MW-2 to <br /> determine the effect of limited groundwater extraction on the contaminant plume Samples <br /> should be collected from MW-2 and MW-4 before and after groundwater extraction to <br /> measure the change in contamination concentrations <br /> As noted in the December 17 correspondence from PHS/EHD, compliance with CCR Title <br /> 23 requires that a Corrective Action Plan (CAP) or Problem Assessment Report (PAR) be <br /> submitted prior to full-scale site remediation. The PAR must delineate the full extent of <br /> contamination After the contamination has been fully defined, Geological Audit will submit <br /> a proposal to prepare a PAR, to include an evaluation of remediation alternatives <br /> 6.0 LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily <br /> exercised by environmental consultants practicing in this or similar localities The findings <br /> were based upon analytical results provided by an independent laboratory Evaluations of <br /> the geologic/hydrogeologic conditions at the site for the purpose of this investigation are <br /> made from a limited number of available data points (i a monitoring wells) and subsurface <br /> conditions may vary away from these data points No other warranty, expressed or implied, <br /> is made as to the professional recommendations contained in this report <br />
