&V A <br /> • A S S O C I A T E S I N C <br /> an average increase in the water table elevation of approximately 2 07 feet since December 2000 <br /> The water level data were used to develop the groundwater elevation contour map (Figure 3) <br /> Assuming that horizontal isotropic conditions prevail, groundwater in the uppermost aquifer <br /> beneath the site generally flowed towards the south The average hydraulic gradient on March <br /> 15, 2001 was calculated to be 0 0006 ft/ft or approximately 3 ft/mile A summary of <br /> groundwater monitoring data is presented in Table 1 <br /> ANALYTICAL RESULTS <br /> TPHd was detected above laboratory detection limits in the samples collected from wells MW3 <br /> and MW4 at concentrations of 110 parts per billion (ppb) and 2,200 ppb, respectively TPHg, <br /> BTEX, and MTBE were not detected in the samples collected from wells MW3 and MW4 The <br /> samples collected from wells MWI, MW5, and MW6 contained no detectable concentrations of <br /> TPHg, TPHd, BTEX, or MTBE Well MW2 was not sampled due to the presence of free <br /> product A summary of analytical results is presented in Table 2 Laboratory data sheets and <br /> chain-of-custody documentation are contained in Attachment 2 <br /> CONCLUSIONS <br /> Concentrations from wells MW 1 and MW3 through MW6 remain generally consistent with the <br /> results from the previous sampling event Free product was still present in well MW2 during the <br /> sampling event The direction and magnitude of groundwater flow is generally consistent with <br /> the previous sampling event, and groundwater elevations have increased since December 2000 <br /> I <br /> w\625Mquart1yUgr-2001 doc 3 <br />
