�. MCL beyond the southern property boundary based on the current
<br /> concentration results for well MW-11 However, the plume does not appear
<br /> to have impacted the two nearby private wells, as indicated by the analytical
<br /> data for samples collected In 2004 The model for TPH-g predicts that the
<br /> concentrations decrease rapidly at a conservative distance of 24 feet from the
<br />' source to be within the goal of 50 mg/L The model indicates that the
<br /> concentration of TPH-g may exceed its associated goal beyond the southern
<br /> property boundary based on the current concentration results for well MW-11
<br /> The first quarterly groundwater-monitoring event of 2005 occurred on January
<br /> 31St through February 1St The depth-to-water measurements indicated that the
<br />' groundwater elevation increased approximately 3 21 feet from the previous
<br /> event During this event, the average depth to groundwater was 45 48 feet bgs
<br /> (-28 80 feet msl) The groundwater flow was easterly to southeasterly at a
<br /> 1 gradient approximately 0 004 feet per linear foot BTEX and/or TPH-g were
<br /> detected in the groundwater samples from wells MW-1, MW-7, MW-11,
<br /> ' MW-12, SP-1, SP-2, SP-4, SP-6, PZ-1, and PZ-2 DIPE and/or TBA were
<br /> detected in the groundwater samples from wells MW-7 and PZ-1 1,2-DCA
<br /> was detected in groundwater samples from wells MW-1, MW-5, MW-7, MW-
<br /> 8, MW-12, and SP-5.
<br /> The second quarterly groundwater-monitoring event of 2005 occurred in
<br /> April The depth-to-water measurements indicated that the groundwater
<br /> elevation increased approximately 174 feet from the previous event During
<br /> this event, the average depth to groundwater was 43 73 feet bgs (-27 06 feet
<br /> msl) The groundwater flow was easterly to southeasterly at a gradient
<br /> approximately 0 004 feet per linear foot BTEX and/or TPH-g were detected
<br /> in the groundwater samples from wells MW-1, MW-7, MW-12, SP-1, SP-2,
<br />' SP-4, SP-6, PZ-1, and PZ-2 DIPE was detected in the groundwater samples `
<br /> from wells MW-7, MW-12, and PZ-1 1,2-DCA was detected in groundwater
<br /> samples from wells MW-7, MW-8, MW-12, and SP-5
<br /> The third quarterly groundwater-monitoring event of 2005 occurred In July
<br /> The depth-to-water measurements indicated that the groundwater elevation
<br />' decreased approximately 130 feet from the previous event During this event,
<br /> the average depth to groundwater was 45 03 feet bgs (-28 36 feet msl) The
<br /> groundwater flow was easterly to southeasterly at a gradient approximately
<br /> 0 003 feet per linear foot BTEX and/or TPH-g were detected In the
<br /> groundwater samples from wells MW-1, MW-7, MW-11, MW-12, SP-1, SP-
<br /> 2, SP-4, SP-6, PZ-1, and PZ-2 DIPE was detected In the groundwater sample
<br />' from well MW-7 1,2-DCA was detected In groundwater samples from wells
