On 02 August 2001, three ground water monitoring wells (MW-1, MW-2 and MW-3), screened <br /> between 20 and 40 feet bsg, were installed at the site (Figure 2) Well MW-1 was installed at the <br /> northeast corner of the site, and wells MW-2 and MW-3 were installed at the southern edge of the <br /> dissolved plume area Two ground water monitoring events have occurred to date, the last one in <br /> January 2002 <br /> I0 Ground water elevation at the site is approximately 15 feet below mean sda level Ground <br /> water at the site as inferred to flow north-northeast <br /> I0 TPH-g,TPH-d and BTEX compounds have not been detected in ground water samples from <br /> wells MW-2 and MW-3 <br /> I0 TPH-g and TPH-d have been detected an well MW-1, the highest concentrations were <br /> detected during the January 2002 morutonng event at 18,000 µg/1 and 9,000 µg/1, <br /> respectively <br /> • BTEX compounds were detected in well MW-1 during the January 2002 monitoring event <br /> at concentrations of 360 gg/1 benzene, 1,600 µg/1 ethylbenzene and 4,700 µg/1 xylenes, <br /> toluene was not detected during the January 2002 monitoring event,but was detected during <br /> the preceding September 2001 monitoring event at 160 gg/l <br /> ® MTBE was detected in the monitoring well sample from well MW-2 at a maximum <br /> Iconcentration of 9 3 µg/I <br /> The lateral and vertical extent of petroleum hydrocarbon-impacted soil and ground water to the <br /> northeast, east and southeast have not been delineated <br /> I <br /> I <br /> I <br /> I <br /> I I <br /> 1 <br /> 1 <br /> I <br />
