Performed one round of water column monitoring at the Silver Lake Outfall (Location 4A) on January 21, 2016. A composite grab sample was collected and submitted for analysis of PCBs (total and dissolved) and TSS. Select field measurements made during the January 21, 2016 water column monitoring event are summarized in Table 20-1.

Obtained a gauge reading at the Silver Lake Outfall on January 21, 2016 as part of the Housatonic River monitoring program. The lake level and flow information for the Silver Lake Outfall are presented in Table 20-2.


See attached tables. (Note: Results from the water column monitoring event performed on December 16, 2015 have not yet been received and will be presented in next month's report.)

ITEM21 GROUNDWATER MANAGEMENT AREAS

PLANT SITE 1 (GMA 1) (GECD310)

JANUARY 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 1, 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 Area 1-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 January.

East Street Area 2-South:

Continued automated recovery operations for groundwater and/or LNAPL (if recoverable) from pumping systems 17W, 64R, 64S, 64V, 64X, RW-2(X), RW-l(S), RW-l(X), RW-4, and E2SC03D (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 January (see Table 21-5).

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

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 January (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 January (see Table 21-8)

Completed optimization efforts (pump cycle adjustment) at automated DNAPL recovery system 2.

Note: After treatment, the majority of the water processed at GE's Building 64G groundwater treatment facility is discharged to the Housatonic 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 facillty is routed to GE's on~site recharge pond located in East Street Area 2-South.

Notes: 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. Far 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.

Notes:

t. Samples were collected by General Electric Company, and were submitted lo ALS Environmental and SGS Environmental Services, Inc. for analysis of volaltles, PCBs, semivolaliles, metals, alkalinity, ammonia, total organic carbon, oil & grease, total dissolved solids, !olal solids and to!al suspended solids.

2. NA· Not Analyzed. 3. ND • Analyte was not detected. The number in parentheses is the associated reporting limit. 4. With the exception of conventional parameters and metals, only those consti!uents detecled in one or more samples are summarized. 5. -· Indicates that alt constituents for the parameter group were not detected.

Data Qualifiers:

Oraanjcs lvola!!les PCBs semivolati!esl J · Indicates an estimated value between the method detection limit (MDL) and method reporting llmit {MAL) • ALS. J 1 - Indicates an estimated value less than the practical quantitation timit (POL} - SGS Environmental Services, Inc.

lnomanics J ·Indicates an estimated value between the method deleclion !imil {MDL) and method reporting limit (MAL).
