The Spiegelberg Landfill Superfund site is located on Spicer Road about 40 miles west of Detroit and 1.5 miles northeast of Hamburg in Green Oak Township, Livingston County, Michigan. The site is surrounded by woods, open fields, and rural residences. An area on the northern part of the property was used for disposal of domestic, industrial, and septic waste materials from as early as 1966 until about 1977. Another area, termed the "paint sludge disposal area" covered about one-half acre in the northern third of the property at the base of a sand and gravel quarry. Sand, gravel, and peat deposits continue to be mined from the property. Preliminary sampling and analysis of groundwater in the paint sludge area indicated the presence of high concentrations of volatile organic compounds (VOCs) and inorganic compounds including lead.
EPA placed the Spiegelberg Landfill site on the National Priorities List (NPL) in September 1983 and deleted it from the NPL on June 13, 2011.
Site ResponsibilityThe Spiegelberg Landfill site is being addressed through potentially responsible party (PRP) actions under federal and state oversight.
Threats and ContaminantsLead and VOCs were detected in the soil and groundwater at the site. Potential health threats to people could have occurred due to ingestion of or direct contact with the contaminated groundwater or soil.
EPA issued a source-control Record of Decision (ROD) for the Spiegelberg Landfill site on September 30, 1986 that called for the removal and off-site treatment of wastes and contaminated soils from the paint sludge and industrial waste disposal areas. EPA, the state of Michigan, and the PRP, Ford Motor Company (Ford), entered into a Consent Decree for the selected cleanup actions on December 28, 1988. Ford later arranged to have all contaminated soil in these areas excavated down to the groundwater table and then disposed of off site.
EPA issued a second ROD on August 31, 1989 to address groundwater contamination through the installation and operation of a groundwater pump-and-treat system with on-site reinjection of the treated water. Ford continuously operated the groundwater pump-and-treat/reinjection system for about two years until EPA issued an Explanation of Significant Differences (ESD) on October 22, 1998 that allowed for intermittent operation of the pump-and-treat sysytem to occur (the system could be shut down, but should be placed on stand-by status for restart, if necessary) and to change the selected groundwater cleanup standards to be consistent with Michigan Department of Environmental Quality Part 201 cleanup standards. The site then entered into a demonstration monitoring period with the intent that pump-and-treat would be restarted if results of a semiannual groundwater sampling event showed that contaminant concentration(s) were present in groundwater above the cleanup standards.
EPA issued a Five Year Review (FYR) report for the Spiegelberg Landfill site on January 8, 2000 and determined that the site cleanup remedies remained protective of human health and the environment.
EPA issued the second FYR Report for the Spiegelberg Landfill site on January 28, 2005. The Agency confirmed that results of the demonstration monitoring period, which consisted of twelve groundwater monitoring events from September 1998 to December 2004, showed continual compliance with the groundwater cleanup standards listed in the ESD and that the results had established that the site had achieved the groundwater cleanup goals. No contaminants of concern had been found at the site above Safe Drinking Water Act Maximum Contaminant Limits (MCLs) since 1998. A Hazardous Substance List (HSL) compound analysis was also conducted and no compounds were detected above risk based levels for the final December 2004 monitoring event. The HSL analysis included all chemicals found during the Remedial Investigation (RI). Conducting the HSL analysis ensured that all chemicals found during the RI were below health-based values at the site. EPA concluded in the second FYR Report that the site remedial actions remained protective of human health and the environment.
EPA issued a Final Closeout Report for the Spiegelberg Landfill site on July 19, 2010 after determining that the PRP had completed all required response actions and that site conditions remained protective of human health and the environment. The Agency then proposed that the site be deleted from the NPL on April 13, 2011 via a notice placed in the Federal Register. EPA deleted the Spiegelberg Landfill site from the NPL on June 13, 2011.
Success StoryEPA determined that the PRP has completed all cleanup response actions and that site conditions are protective of human health and the environment. The Agency issued a Final Closeout Report on July 19, 2010 and deleted the Spiegelberg Landfill site from the NPL on June 13, 2011.
