Site Description

The Ottati & Goss/Kingston Steel Drum (O&G/KSD) site, a 35 acre former drum recycling and reconditioning center, is located approximately 3 miles south of the center of Kingston, NH. The site historically consisted of drum recycling operations involving heavy sludges, incinerator residue, and drum residuals. Wastewater from the operations contaminated the South Brook and Country Pond, killing fish and vegetation. The facility operated from the late 1950s until approximately 1980. The site consists of four Operable Units, or cleanup projects. Operable Unit 1 (OU1) refers to a Potentially Responsible Parties (PRP) lead cleanup of soil on the O&G portion of the site which was completed in 1989. Operable Unit 2 (OU2) refers to a PRP-lead groundwater cleanup design which was not completed due to a cash-out settlement in 1993. As a result of this settlement, OU2 was suspended and was superseded by Operable Unit 3 (OU3) which is currently designated as the groundwater operable unit. Operable Unit 4 (OU4) is designated as the remediation of soil and sediments on the KSD portion of the site which was completed in 2002.

Current Site Status and Cleanup Actions to Date

  • Between 1981 and 1984, EPA and private party cleanup actions at the site included the installation of security fencing, packing and removing leaking drums, and removing tons of contaminated soils and debris. Approximately 12,800 tons of soil, drums, and metals; 101,700 tons of flammable sludge; 6,000 cubic yards of flammable liquid; and other materials were removed.
  • Contaminated soil within the 1 acre, O&G portion of the site was excavated and treated by the PRPs between 1988-1989. Approximately 4,700 cubic yards of contaminated soils were treated onsite by low temperature thermal aeration at a cost of roughly $2 million.
  • In 1993, the governments entered into a cash-out settlement with the previous and current owners and approximately 355 other parties responsible for waste at the site. As a result of the settlement, the United States received $1.2 million. The State of New Hampshire received $2.8 million.
  • In 1993, EPA completed the demolition of the 20,000 square foot building located on the KSD portion of the site. The demolition activities included asbestos cleanup, building debris removal and disposal, utilities removal, and above ground and under ground storage tank removal.
  • From August 2001-June 2002, approximately 72,000 tons of PCB and VOC-contaminated soils were excavated from a portion of the site. These soils were treated on-site using a low temperature thermal desorption (PDF) (65 K, 2 pp) unit. In addition, approximately 9,000 tons of sediment was excavated and disposed of off-site while an additional 500 tons of sediment was transported to a PCB hazardous waste facility.
  • EPA restored a six-acre wetlands with more that 20,000 cubic yards of wetland material and constructing 261 hummocks, approximately 10 hummocks for every 10,000 square feet in the restored area.
  • The site is currently being evaluated for the type and configuration of the groundwater cleanup system that will be needed to complete the final phase of cleanup at the site. The discovery of 1,4-dioxane in the groundwater at the site has recently delayed completion of the Remedial Design until 2005.
  • EPA continues to monitor the site to ensure there is no immediate threat to human health or the environment pending implementation of the last phase of cleanup for the groundwater.

Current Funding Status

  • As of January 2004, EPA has spent approximately $34.8 million in response costs at the site.
  • EPA expects to consider funding the last phase of cleanup at the site beginning in Fiscal Year 2006 upon completion of the Remedial Design in September 2005.

Key Accomplishments

  • EPA has expended approximately $35 million in response costs at the site.
  • All soil, sediment and building contamination found at the site have been cleaned up.
  • Remedial Design activities for the final phase of groundwater cleanup are ongoing with an expected date for completion of design in 2005.
