stream and fairly high CO2 content (+10,) at the beginning of the test and the CO2 did not seem to decrease in concentration (+10°s) at any time during the test MW4 did not show any significant Petroleum concentration to the vapor stream (however ground water contamination has been shown at very low levels) and yet CO2 content was relatively high (+80) After ' stripping' the well for approximately one hour the CO2 concentration decreased (6 750-.) , this CO2 may be the by-product of the aerobic microorganisms' degradation of petroleum and this observed decline in CO2 suggests that there is significantly more oxygen available to MW4 than to MW8 , for this activity The effluent of the vapor stream from the VE test (after carbon canisters) was taken and analyzed at both WEGE' s ' in-house' FID chromatograph and American Environmental Network' s lab Methane was observed but not quantified in WEGE' s analysis of the effluent This methane generation in the subsurface suggests that anaerobic bio-activity may also exist for degradation of petroleum hydrocarbons CONCLUSIONS 1 Eight monitor wells were sampled. MW1 , MW2 , MW4 , MW5, MW6 and MW7 showed no detectable levels of contamination 2 MW3 and MW8 have levels of Total Fuel Hydrocarbons as gasoline of 0 2 and 7 4 mg/L and Benzene of 4 and 1300 µg/L, 40 respectively 3 The ground water flow direction is presently in a south southwesterly direction from MW1 to MW3 and south southeasterly from MW3 to MW7 The current ground water elevation gradient between MW1 and MW7 averages 0 002 feet per linear foot 4 Sl and S2 were not sampled, these wells were dry LIMITATIONS The discussion and conclusions presented in this report are based on the following 1 The observations and data collected by field personnel 2 The results of laboratory analyses performed by a state certified lab 5 USA 65 Sept 195 Qtr Rpt
