The Shpack Landfill covers 9.4 acres, most of which are within the Town of Norton , with the remaining 2 acres in the City of Attleboro. The landfill was operated from 1946 until the 1970s. This landfill received domestic and industrial waste, including inorganic and organic chemicals, as well as radioactive waste. The area near the site includes a wooded swamp. Approximately 40,000 people live within a 3-mile radius of the site. Municipal water supplies for both townships do not extend to the area around the site. Therefore, residents in this area use private drinking water wells, most of which withdraw water from the bedrock aquifer. The distance from Shpack Landfill to the nearest residential well is about 150 feet. There are 27 private wells within 1 mile of the site that serve 103 people. The two municipal water supply well fields for Norton are situated in the shallow aquifer and are located 3 miles east and 5 1/4 miles northeast of the area. Municipal well fields for Attleboro also are completed in the shallow aquifer and are located 12,000 feet and 24,000 feet west of the study area. The Shpack Landfill directly borders the 55-acre Attleboro Landfill Inc. facility.
Threats and Contaminants
The groundwater contains volatile organic compounds (VOCs) including vinyl chloride and trichloroethylene (TCE), as well as heavy metals including chromium, barium, copper, nickel, manganese, arsenic, cadmium, and lead. Sediments on the edge of the swamp and soils contain radionuclides including radium and uranium. Surface water in the swampy area is contaminated with radium and alpha and beta particles, as well as organic compounds. The site is fenced to limit access. Prior to the cleanup, people who trespassed on the site could be exposed to contamination by coming into direct contact with or accidentally ingesting contaminated groundwater, surface water, soil, or sediments.
Cleanup Approach
The site is being addressed in a long-term remedial phase focusing on cleaning up the entire site.
Response Action Status
| Entire Site | An investigation into the nature and extent of the contamination at the site was begun by the potentially responsible parties in 1990. Through sampling and characterization of soil, sediments, surface water, and groundwater, the investigation defined the contaminants of concern and will recommended alternatives for the final cleanup. The results of the first phase of study was released in 1993. A second phase of study was completed during 2003. This work is being performed by a group of settling responsible parties. The US Army Corps of Engineers Formerly Utilized Site Remedial Action Program (FUSRAP). conducted studies of radiological contamination at the Site in 2000 and 2002 to develop a final cleanup plan of radiologically contaminated materials. EPA's final cleanup plan was selected in 2004.
Sampling of residential wells has not shown significant levels of site related contaminants. The sampling of residential wells to date has been generally within federal drinking water guidelines, with the exception of iron and manganese; which are common naturally occurring contaminants in the Norton area.

Environmental Progress
Cleanup work for radiological contamination, under the supervision of the US Army Corps of Engineers and chemical contamination under the supervision of EPA have bee completed.
Current Site Status
A walkover gamma radiation survey was performed by the Corps of Engineers FUSRAP program during 2000. The Corps completed additional sampling at the Site during the summer of 2002. Potentially Responsible Parties (PRPs) performed groundwater, soils, and sediment sampling during the summer of 2002 and the spring of 2003, including the replacement of several damaged wells. The Shpack PRP Group completed the Remedial Investigation (RI) and Feasibility Study in June 2004. The Feasibility Study was completed by the PRP Group in June 2004. The Human Health Risk Assessment and Baseline Ecological Risk Assessment was completed by EPA's contractor, Metcalf and Eddy in June 2004. The Proposed Plan was announced at a public meeting held in Norton, MA on June 23, 2004. The Feasiblity Study and Proposed Plan are available online in the "Links to Other Site Information" section below.
The Public Hearing for the Proposed Plan was held on August 4, 2004. The Record of Decision was signed on September 30, 2004.
The final ROD calls for the excavation and disposal of about 35,000 cubic yards of waste that exceeds cleanup standards. The remedy, referred to as SC-3B, was selected after an extensive comment period during which the public and community leaders weighed in heavily in favor of excavating all waste exceeding the cleanup standards. Prior to issuing its final cleanup decision, EPA solicited public comment between June and August 2004 on a proposal to excavate 10,500 cubic yards of waste exceeding cleanup standards and to cap some of the material and leave it at the site.
EPA estimates the total cost of the selected cleanup plan to be about $43 million. The Record of Decision comprises two response actions: one managed by the U.S. Army Corps of Engineers and one led by EPA. In accordance with special legislation passed in 2002, the Army Corps of Engineers will be conducting the cleanup of the radiological contamination at the Shpack site. The Army Corps cleanup began in September 2005 and is expected to continue through fall 2010 . The Army Corps cleanup was suspended for approximately one year (June 2006-June 2007) due to lack of funding. The Army Corps then resumed work which was completed in 2012.
The ROD includes the following major components:
- Excavation and off-site disposal of approximately 34,000 cubic yards of soil and 1,000 cubic yards of sediment from Chartley Swamp which exceed the radiological and chemical cleanup levels for the site.
- Following excavation, impacted wetlands will be restored or replicated and clean fill will be used to backfill and bring open areas up to grade, as necessary.
- Extension of the public water supply line to two residences adjacent to the site that currently have private wells.
- Implementation of institutional controls to restrict future use of the property and groundwater.
- A traffic control plan will be designed to manage the increased volume of truck traffic associated with transporting contaminated material off-site. EPA will closely coordinate these activities with local, state and federal partners prior to beginning the cleanup. The Army Corps of Engineers has developed a traffic control plan with input from local and state authorities which will be used to manage truck traffic during the cleanup at the site.
Remedial Design/Remedial Action (RD/RA) negotiations began on August 15, 2006, when EPA issued Special Notice letters to 17 parties. Since that time, another 4 parties have been issued Special Notice Letters. A good-faith offer was received by 10 parties on October 19, 2006. Another 4 parties have joined the negotiations since that time. The RD/RA consent decree was signed by 14 parties and was lodged in the U.S. District Court in Boston on December 8,2008, and entered on January 27,2009. Under the terms of the consent decree, the defendants will perform the remainder of the site-wide cleanup of chemical wastes and other contaminants. The work is estimated to cost $29 million. The defendants signing the agreement include: the City of Attleboro, Mass.; Avnet Inc.; Bank of America N.A. (Trustee u/w of Lloyd G. Balfour); BASF Catalysts LLC (formerly known as Engelhard Corporation); Chevron Environmental Management Company (for itself and on behalf of Kewanee Industries Inc.); ConocoPhillips Co.; Handy & Harman; International Paper Co.; KIK Custom Products, Inc. (formerly known as CCL Custom Manufacturing Inc.); Town of Norton, Mass.; Swank Inc.; Teknor Apex Co.; Texas Instruments Inc.; and Waste Management of Massachusetts Inc.
Cleanup of chemical contamination proceeded following the Army Corps of Engineers cleanup efforts. All site-related cleanup construction was completed in 2014.
