Actual Aroclor 1221is not present in the sample, but is reported to more accurately quantify PCBs present in a sample that has undergone environmental alteration. PD Aroclor 1242 is being used to report an altered PCB pattern exhibited by the sample. Actual Aroclor 1242 is not present in the sample, but is reported to

more accurately quantify PCBs present in a sample that has undergone environmental alteration.

GROUNDWATER MANAGEMENT AREAS

PLANT SITE 1 (GMA 1)

(GECD310)

JANUARY 2011



General:

- Conducted routine groundwater elevation and NAPL monitoring/recovery activities, including quarterly monitoring round.

- Conducted survey and maintenance activities at selected monitoring wells.

- Conducted waste characterization analyses on soil cuttings, development water, and debris from well maintenance activities, as indicated in Table 21-1.

East Street Area 1-North and South:

- Continued automated groundwater and NAPL pumping at North Side and South Side Caissons. No LNAPL was removed from the North Side Caisson in January. No LNAPL was removed from the South Side Caisson in January.

- Continued routine well monitoring and manual NAPL removal activities. Approximately 0.678 liter (0.179 gallon) of LNAPL was removed from this area during January.

East Street Area 2-South:

- Continued automated groundwater and LNAPL removal activities. A total of approximately 3,907,863 gallons of groundwater was recovered from pumping systems 64R, 64S, 64V, 64X, RW-1(S), RW-1(X), and RW-2(X). In addition, approximately 538 gallons of LNAPL were removed from pumping systems 64R, 64V, GMA1-17W, RW-1(S), RW-2(X), RW-4, 64X, and 64S Caisson.

- Continued automated DNAPL removal activities. Approximately 30 gallons of DNAPL were removed from pumping system RW-3(X) during January.

- Continued routine well monitoring and manual NAPL removal activities. Approximately 27.122 liters (7.156 gallons) of LNAPL were removed from wells in this area during January. Approximately 4.133 liters (1.091 gallons) of DNAPL were removed from wells in this area during January.
