Ground water at the site is currently in a recharge cycle. <br /> Previous discharge and recharge cycles at the site have produced <br /> sporadic traces of TFH or BTEX constituents in some of the <br /> monitoring wells . The ' spotty' occurrence of contamination in <br /> MW4 does not appear to be solely related to depths of the aquifer <br /> but are probably representing a localized ground water flow from <br /> stratigraphy not recognized from well to well at the site . <br /> CONCLUSIONS <br /> 1 . Eight monitor wells were sampled. MWl, MW2, MW3 , MWS, MW6 <br /> and MW7 showed no detectable levels of contamination. <br /> 2 . MW4 and MW8 have levels of Total Fuel Hydrocarbons as <br /> gasoline of 0 . 3 and 7 mg/L and Benzene of 8 and 500 µg/L, <br /> respectively. <br /> 3 . The ground water flow direction is presently in a south, <br /> southwesterly direction from MW1 to MW7 . The current ground <br /> water elevation gradient between MWI and MW7 averages 0 . 003 <br /> feet per linear foot . <br /> 4 . S1 and S2 were not sampled; these wells were dry. <br /> LIMITATIONS <br /> The discussion and conclusions presented in this report are based <br /> on the following: <br /> 1 . The observations and data collected by field personnel . <br /> 2 . The results of laboratory analyses performed by a state <br /> certified lab. <br /> 3 . Our understanding of the regulations of the State of <br /> California and San Joaquin County and/or City of Lodi, <br /> California. <br /> 4 . Review of existing literature concerning this site and the <br /> San Joaquin County area. <br /> Changes in ground water conditions can occur due to variations in <br /> rainfall, temperature, local and regional water usage and local <br /> construction practices . In addition, variations in the soil and <br /> ground water conditions could exist beyond the points explored in <br /> this investigation. <br /> 5 USA 65 Mar. ' 95 Qtr Rpt <br />
