ITEM21 GROUNDWATER MANAGEMENT AREAS

PLANT SITE 1 (GMA 1) (GECD310)

FEBRUARY 2016



General:

Conducted routine groundwater elevation monitoring and non-aqueous-phase liquid (NAPL) monitoring/recovery activities. The thicknesses of LNAPL and DNAPL measured during these activities are shown in Table 21-1.

Continued routine manual LNAPL and DNAPL removal activities at various wells within GMA I, as indicated in Tables 21-2 (for LNAPL) and 21-3 (for DNAPL).

Note: The following entries identify additional activities conducted within specific Removal Action Areas within GMA 1.

East Street Arca I-North and South:

Continued automated recovery operations for groundwater and LNAPL (if recoverable) at the Northside and Southside Caissons (see Table 21-4). No LNAPL was recovered from either caisson in February.

East Street Area 2-South:

Continued automated recovery operations for groundwater and/or NAPL (if recoverable) from pumping systems l 7W, 64R, 64S, 64V, 64X, RW-2(X), RW-l(S), RW-l(X), RW-4, and E2SC-03D (see Table 21-5).

Did not conduct automated recovery of DNAPL from pumping system RW-3(X), since this system was shut down for maintenance and due to plugging with sand throughout February (see Table 21-5).

Continued treatment/discharge of water through the Building 64G Groundwater Treatment Facility (GWTF) (see Table 21-6).

ITEM21 (cont'd)

GROUNDWATER MANAGEMENT AREAS PLANT SITE 1 (GMA 1)


a. Activities Undertaken/Completed (cont'd)

Lyman Street Area

Continued automated recovery operations for groundwater from pumping systems RW-1 R and RW-3 (see Table 21-7). LNAPL recovery (if any) from these pumping systems would be performed manually, but there was no such recovery in February (see Table 21-2).

Newell Street Area II:

Conducted automated recovery operations for DNAPL at System 2 (which is composed of wells N2SC-Oll(R), N2SC-031(R), and N2SC-14), but there was no DNAPL recovery in February (see Table 21-8).

Silver Lake Area:

Conducted routine monitoring of the Jake level and discharges at the outfall as part of the Housatonic river water column monitoring program. (See Item 20.a above.)

b. Sampling{fest Results Received

See attached tables.


Submitted Long-Term Monitoring Program Monitoring Event Evaluation Report for Fall 2015 (February 26, 2016).

Note: After treatment, the majority of the water processed at GE's Bulldlng 64G groundwater treatment facility Is discharged to the Housalonlc River through NPDES permitted Outfall 005. However, as part of GE's overall efforts to contain NAPL within the site and to optimize NAPL recovery operations, a portion of the treated water discharged from the 64G facility is routed to GE's on-site recharge pond located in East Street Area 2-South.

~ 1. Volume of water pumped is total from Wells RW-1 R, RW-2, and RW-3. 2. ••• indicates NAPL was not recovered by the system. 3. For the week ending August 28, 2014, depression pump system float switch failure at Well RW-3.

Issues exist with the manufacturer's replacement switches which caused intermittent periods where the system was not functioning. Estimated total downtime for this period is 96 hours (14.29% downtime).

4. For the week ending September 4, 2014, depression pump system float switch failure at Well RW-3. Issues exist with the manufacturer's replacement switches which caused intermittent periods where the system was not functioning. Estimated total downtime for this period Is 160 + 167 hours (48.66% downtime).

5. Effective November 2014, LNAPL recovery (if any) from RW-3 is reported as manual recovery and included In the LNAPL Monitoring and Manual Recovery table of the monthly report.
