The March 2004 sampling event indicates that three of <br /> the six sampling locations were non-detect for vecs. Low levels <br /> of various vecs were detected in the other three sampling <br /> locations (all located within Parcel 88); however, only a single <br /> detection of 1,1,2-TCA (7.2 ~g/L at SHGW02) exceeded its <br /> respective MCL (5.0 ~g/L). The evaluation of sampling data <br /> indicates there is evidence that natural attenuation is occurring and <br /> that the VOC plume is not migrating off OU3. Site groundwater is <br /> not in use. <br /> The 1999 ROD identified the selected remedy for VOCs in <br /> groundwater (Parcel 88) as monitored natural attenuation. <br /> Groundwater monitoring for VOCs and natural attenuation <br /> indicators will continue until regulatory approval to discontinue <br /> monitoring is obtained.
