The gradient is 0.003 ft/ft in <br /> easterly direction and is consistent with past monitoring (Table <br /> 1) . Attachment 1 contains well/purge logs. <br /> March 13, 1991, monitoring wells MW1, MW2, M114, MW5, MW6, MW7, <br /> On M <br /> and arc ndwater samples were analyzed for <br /> MW8were sampled.

A sample ow could o of be <br /> dissolved <br /> from MW3 because it was nearly drylevels <br /> hydrocarbons were found in wells MW1, MW2, and MW4. Well MW5 <br /> contained higher levels of dissolved hydrocarbons than the other <br /> wells (Fable 2) . <br /> Soil and groundwater samples were sent to Applied Analytical <br /> Laboratories, State license #1211, for analysis (Table 2) .
