Groundwater flow was determined to be <br /> southwesterly at an approximate gradient of 0:1%: <br /> N . Separate-phase petroleutn'was not detected in any,of the monitoring wells. <br /> " • TPHg and BTEX were not `detected in gr undwater samples collected from <br /> monitoring wells MW-1, MW-2 and.MW-3. TPHd was detected at 150, 330 and <br /> 100 ppb, respectively . = 1 <br /> I <br /> D-104 SWI 4 May 1, 1995 <br />
