' Groundwater <br /> During drilling, groundwater was initially encountered at <br /> approximate depths ranging between 9 5 and 19 feet below the ground <br /> ' surface After the wells stabilized, groundwater was encountered at <br /> an approximate depth of 5 feet below the ground surface Therefore, <br /> groundwater at the site appears to be confined <br />' The potentiometnc surface defined during this study suggests that <br /> the groundwater gradient is towards the southeast However, it is <br /> possible that the gradient shifts with tidal fluctuations <br /> Perched groundwater 2s locally situated beneath the former UST <br /> location in the vicinity of MW-2A The groundwater at MW-2A <br />' contains free product which was measured to be less than 0 01 feet <br /> thick No groundwater samples were collected from MW-2A for <br /> analysis <br /> TPH as gasoline and TPH as diesel were detected in the groundwater <br /> sample from MW-1A The concentrations of TPH as gasoline and <br />' TPH as diesel in the groundwater from MW-1A were measured at 23 <br /> ppm and 2 8 ppm, respectively. TPH as gasoline and TPH as diesel <br /> were not detected in the groundwater samples from MW-3A and <br /> MW-4A <br /> BTEX compounds were detected in the groundwater samples from <br />' MW-1A and MW-3A In groundwater from MW-1A, measured <br /> concentrations of benzene, ethylbenzenes and xylenes exceed <br /> maximum contaminant levels (MCLs) for drinking water The <br /> measured concentrations of BTEX compounds in groundwater at <br /> MW-3A were at levels below the MCLs for drinking water <br /> No gasoline, diesel or related petroleum constituents were detected in <br /> the groundwater from the monitoring well inside the warehouse <br /> building (MW-4A) <br /> 1 <br /> I <br /> 5-2 <br />
