Site DescriptionThe 40-acre Duell & Gardner Landfill site, located in Dalton Township, Muskegon County, Michigan, was an operating municipal landfill from the 1940s to 1975. Before 1969, industrial waste and general refuse were accepted at the site. From 1969 to 1973, the landfill was operated as a licensed solid waste disposal facility. In 1971, the Michigan Department of Public Health (MDPH) stipulated that no liquid waste was to be disposed of in the landfill; however, in 1973, the MDPH noted that liquid waste disposal was occurring. The landfill ceased operations in 1975. Wastes were deposited on the soil surface and in surface depressions.
Materials found on the site included: approximately 500 drums in various stages of deterioration, hundreds of laboratory bottles, areas of refuse and debris, and piles of unidentified sludge-like material. Volatile organic compounds (VOCs), including chloroform, carbon tetrachloride, aniline, and N,N-dimethylaniline, have been detected in onsite groundwater. Polychlorinated biphenyls (PCBs), crystal violet, aniline, and N,N-dimethylaniline were detected in onsite soil. Potential health risks may exist for individuals who have direct contact with or ingest contaminated groundwater or soil. Approximately 140 people live within a one-mile radius of the site.
The site is being addressed through Federal and State response actions.
Threats and ContaminantsVOCs, including chloroform, carbon tetrachloride, aniline, and N,N-dimethylaniline, have been detected in onsite groundwater. PCBs, crystal violet, aniline, and N,N-dimethylaniline were detected in onsite soil. Potential health risks may exist for individuals who have direct contact with or ingest contaminated groundwater or soil.
Cleanup ProgressIn 1986, under Federal authority, the United States Environmental Protection Agency (EPA) removed approximately 550 drums, the laboratory bottles, sludge-like material, and general refuse and debris. The site was posted to reduce the potential for exposure to remaining contaminants.
In December 1986, the state began an investigation to determine the type and extent of groundwater and soil contamination which remained at the site and to identify alternative technologies for the cleanup. Based on the results of the investigation, a remedy, including low-temperature treatment of contaminated soil, carbon adsorption treatment of groundwater, and capping of the landfill, was selected in fall 1993.
A Unilateral Administrative Order was issued by the EPA on June 22, 1994. The potentially responsible party (PRP), CPC International, began design of the remedy in 1994. In July 1999, the PRP ceased all work, after receiving a favorable legal decision on the issue of its underlying liability at the site. Currently, the EPA and the State of Michigan are addressing the remaining cleanup through fund-financed action.
Predesign work indicated that approximately 200 cubic yards of contaminated soil remains. Predesign groundwater investigations concluded that the contaminant concentrations had declined and had not migrated from the site. Based on these findings, a Record of Decision amendment was signed on June 29, 2001 to include soil excavation with offsite disposal, groundwater extraction and treatment, on-site consolidation and capping of contaminated soils. The Remedial Action was determined operational and functional in August 2002. The Long Term Remedial Action (LTRA) of groundwater extraction and treatment is currently on-going at the site under EPA oversight. LTRA will continue until August 2012 at which time, Operation and Maintenance of the remedy under the State of Michigan's oversight will begin.
A Five Year Review was completed in September 2005. This review found that the remedy was protective in the short-term. However, in order for the remedy to be protective in the long-term; institutional controls, such as a restrictive covenant on the property, needed to be implemented and enforceable. On October 30, 2007, a Restrictive Covenant was signed by the property owners and filed in the Muskegon County Michigan Register of Deeds office.
In October 2009, a second Five Year Review began and was signed in March 2010. The review determined that the remedy is protective of human health and the environment because impacted soils have been removed; wastes have been consolidted into a 4-acre landfill and covered with an impermeable cover; impacted groundwater is currently being recovered and treated on site; and Institutional Controls to restrict current and future use of the site have been implemented.
Based on groundwater sampling analysis which showed that there were no groundwater contaminants detected above clean up levels, EPA and MDEQ determined that the treatment system could be shut down in accordance with the Groundwater Monitoring Plan. The system was shut down in June 2010 and the contaminant levels remain under clean up goals. If the next two sampling events (scheduled December 2011 and March 2012) continue to show non-detect for groundwater contaminants, the groundwater remedy will be considered complete and the treatment system will be decommissioned prior to the transfer of the site to the state in August 2012.
