1.1.1 Incident Category
Time Critical Removal Action - see Closure Memorandum July 21, 2014
1.1.2 Site Description
The Site is an approximate 30' by 400' strip on the outer edge of the parcel at 31 Water Street, along the banks of the Powow and Back Rivers. There is a paved, public walkway/bike path on this strip which forms the eastern and southern borders of the property, and is used by the general public. The lot is open, inactive, level and contains areas with concrete foundations from the former on-site manufacturing building. The parcel is bordered to the north by Water Street, to the west by the City of Amesbury Public Works Department building, to the east by the Back River, and to the south by the Powow River. There are steep slopes both along eastern and southern sides leading to the Back and Powow Rivers. The riverbank slopes leading to the Back River and portions of the Powow River slope have been stabilized with crib work; several pipes also protrude from the Back River bank.
1.1.2.1 Location
The 31 Water Street Site property is located at 31 Water Street in Amesbury, Essex County,
Massachusetts. The geographic coordinates of the approximate midpoint along the center of 31
Water Street are 42° 51′ 22.1″ north and 70° 55′ 38.5″ west. The property is identified by the Amesbury Assessor's Office on Map 53, Lot 103 and is bordered to the north by Water Street, to the west by the City of Amesbury Public Works Department building, to the east by the Back River, and to the south by the Powow River.
1.1.2.2 Description of Threat
The presence of Aroclor-1254 at levels up to 740 mg/Kg in soil samples collected by EPA and others indicates that an uncontrolled release of PCBs has occurred at some unknown time in the past at this Site, resulting in contamination to surface and subsurface soils adjacent to the Powow River and the Back River. The origin, amount and intended use (if any) of Aroclor-1254, or in historical fill at this Site has not been determined and is likely to remain unknown. PCBs are the primary contaminant of concern at the Site. Elevated concentrations of lead, arsenic, chromium above the EPA Removal Management Levels have also been identified in the soils at the Site and will be addressed in the Removal Action. State standards for the existing and planned site use are also exceeded.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
In May, July and October 2014, the EPA performed three rounds of surface and subsurface sampling for the Preliminary Assessment/Site Investigation (PA/SI). Over 50 locations were sampled from surface and subsurface locations and analyzed for PCBs and metals. For more details please see POLREPS 1-4.

2.1.1 Narrative
For prior activities, please see POLREPS 1 to 4.
In June 2015 exacation of contaminated soil and backfill with clean fill was completed, the sheet pile wall rendered to it's final height and transport & disposal of waste streams has commenced.
2.1.2 Response Actions to Date
Please refer to POLREPs #1 - 4 for information regarding previous response actions.
Excavation of contaminated soil and backfill with clean soil was completed on 6/18/2015. Excavation confirmation sampling by field screening methods indicated project cleanup goals were met; average concentrations of excavation floors and walls were less than Massachusetts DEP S-1 standards for unrestricted use. Fixed lab analytical results received to date have confirmed the field screening results.
Final site grades, elevation, erosion control methods and final sheet pile wall height were confirmed with the City and MassDEP. The sheet pile wall was cut or driven to it's final elevation of approximately one foot above mean high tide. Initial backfill and grading was completed.
198 tons of contaiminated soil from TSCA grids was shipped off-site on 6/25 - 6/26/2015. Off site disposal bids and clearance have been recieved for the 1400 tons of non-TSCA contaminated soil and the 50 cubic yards of root balls/stumps and crib wall debris.
The sheet pile contractor has fabricated and is installing the sheetpile wall cap.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
