• In previous quarterly reports, we recommended conducting an aquifer pumping test of GT-10 to <br /> obtain data on the groundwater flow rate and to test the feasibility of groundwater extraction as a <br /> potential remediation method A work plan based on computer simulations of a pumping test under <br /> various scenarios was submitted in May to San Joaquin County PHS/EHD, but PHS/EHD has not <br /> commented on this work plan The water level has now dropped almost to the base of the Modesto <br /> aquifer in the proposed pumping well and an aquifer test is not feasible at this time The test will <br /> not be feasible until the static water level begins to rise again during the first quarter of 2001 <br /> We recommend monitoring the site again in early September Because the present groundwater <br /> flow direction is to the southeast,the domestic water well on the Barbot property should be sampled <br /> at that time if possible That well has not been sampled since the middle of 1999 <br /> • <br /> 4 <br />
