During this reporting period the Responsible Party's contractor, ERM Inc., continued weekly oil extraction activities. The total liquids extracted thru 12/27 includes 21,659gals of contaminated water and 3,590 gals of fuel oil. Weekly extraction events will continue. Recovered diesel was transferred to a new permitted AST at the Fogle's facility for disposal. Following each extraction event, the contaminated water was passed thru a series of carbon filter units to a 500 gal holding tank. Water was than discharged to stream as per NPDES permit. A sample of this efluent was retrieved on 12/13/05 and tested for benzene, ethylbenzene, toluene, total xylenes, methyl tert-butyl ether and tert-butyl alcohol as per the permit.
ERM and Fogle's personnel will continue to inspect and replace sorbents in the creek as part of the required work under this AOC.
On 12/05/05, three additional 4 inch diameter monitoring wells were installed at the site as part of the Abatement Plan. The wells were constructed with 15 feet of well screen placed across the water table. Free product was not detected in any of these new wells.
Excavation of both anomaly areas as described in POLREP 15 will occur during the next reporting period. Both areas are located on Fogle's property. Both anomalies were detected during a geophysical survey conducted under the Extent of Contamination Study.
