Site Description
[Back to Top]

From 1946 through 1969, 4 acres of the 235 Salem Acres site received sludge, grit, and grease from the South Essex Sewerage District through an agreement with the owners. This sludge contained tannery waste. The sludge was placed in eight unlined, uncovered disposal pits. Polychlorinated biphenyls (PCBs), volatile and semi-volatile organic compounds, arsenic, and chromium were found to be present in the pits. In addition, there is a fly ash disposal area adjacent to the sludge lagoons and an old landfill area adjacent to the fly ash pile yielding a site total of 13 acres of contamination. Residential housing borders the site on the south and the east. Approximately 65,000 people live within 1 mile, and 127,000 people live within 3 miles of the site. One of the disposal pits is located approximately 20 feet from Strongwater Brook. The site lies on the divide of two drainage basins that channel both surface water and groundwater directly into two major aquifers.

Threats and Contaminants
[Back to Top]

The on-site soils and sludge were contaminated with PCBs, volatile and semi-volatile organic compounds, arsenic, and chromium. There was also a landfill and fly ash pile at the site which contained many of the same contaminants as the sludge lagoons. All areas have been excavated and the materials transported off site to secured landfills. The site has been restored to its natural vegetation. The site will now allow for unrestricted land use.

Cleanup Approach
[Back to Top]

The site was addressed in two stages: initial actions and a long-term remedial phase focusing on cleanup of the entire site.

Response Action Status
[Back to Top]

Initial Action In 1988, the EPA covered the sludge pits with a high density, polyethylene synthetic cap, removed the liquid wastes from the disposal pits to an off-site storage facility, and constructed concrete cut-off walls to prevent further releases into the wetlands. In 1990, repairs were made to a monitoring well and a security fence on site, and signs were posted to further restrict access.

Entire Site The South Essex Sewerage District completed an investigation into the nature and extent of the soil and sludge contamination in early 1993. The investigation defined the contaminants of concern and recommended alternatives for final cleanup. The EPA selected a final remedy for the site, which included sludge-fixation with fly ash and other substances such as cement and soil, as necessary and disposed of off-site to a secured landfill. A contingent remedy includes the installation of an EPA- approved cap. In 1995, the fly ash area and "old landfill" on site were excavated and the contaminated material was taken off site to a permitted landfill. Final site restoration of these areas occurred in 1996. The sludge lagoon cleanup was completed in the Fall of 1997 and final site restoration was completed in the Spring of 1998. In the summer of 1999, Massachusetts Electric Company removed approximately 1,000 cubic yards of the fly ash from the wetland adjacent to the former fly ash pile.

Enforcement HighlightsOn May 26, 1987, the EPA signed a Consent Order with the South Essex Sewerage District to have the District perform the studies to examine the nature and extent of contamination and present technical options for cleanup. In December 1993, the EPA signed a Consent Decree with the South Essex Sewerage District to clean up the lagoons. EPA also signed a separate Consent Decree with the Massachusetts Electric Company to clean up the fly ash pile on site. In October 1994, the EPA signed a Consent Order with DiBase Salem Realty Trust, the owner of the property and remaining potentially responsible party, to clean up the landfill and three debris piles.

Environmental Progress
[Back to Top]

The EPA has assessed the conditions at the Salem Acres site and has determined that the initial capping and liquid waste removal actions, combined with the site security measures taken and the three remedial actions completed, the potential for exposure to contamination has been eliminated. The landfill area, debris piles, the fly ash pile and the sludge lagoons and associated contaminated soils have been excavated and the contaminated materials shipped off site to secured landfills. Final site restoration of these areas was completed in the Spring of 1998. In the summer of 1999, fly ash was removed from the wetland adjacent to the former fly ash pile. The wetland was restored at this time. The site was officially deleted from the National Priorities List (NPL) effective July 23, 2001. The site now allows for unrestricted land use.

Current Site Status
[Back to Top]

The site attained construction complete status in September 1999. A Notice of Intent to Delete is currently scheduled for the Spring 2001. All three potentially responsible parties have fulfilled the requirements of their consent decrees. On July 23, 2001, the site was deleted from the NPL. Future land use is unrestricted.
