Last Updated: September, 2014
The 56-acre Adams County Quincy Landfills #2 and #3 ("Adams County Landfill") site is located in west central Illinois on Old Broadway Road south of Illinois Route 104, approximately five miles east of the city of Quincy. The landfill was privately operated from 1967 until 1972, when Quincy began leasing the landfill from the owner. Quincy operated the landfill from 1972 until 1978, closing it to receipt of waste in fall 1978. Site closure, including placement of a final cover, was completed in mid-1979. The city purchased the Adams County Landfill site in 1982.
Refuse, domestic waste, and industrial waste were disposed of at the site. Liquid industrial waste received at the landfill includes: acids; sludges containing heavy metals; spent nonhalogenated solvents; spent halogenated solvents; wastewater treatment sludge from electroplating facilities; hydraulic oil; machine coolants; thinners; paint solvents and sludge; methyl chloroform; selenium; toluene; methylene chloride; acetone; chloroethene; lacquer thinners; metal etchers; cutting and grinding oils; and caustic cleaning solutions.
Site ResponsibilityThe Adams County Landfill site is being addressed through potentially responsible party (PRP) actions under state and federal oversight.
Threats and ContaminantsVolatile organic compound (VOC) contamination has been documented in groundwater monitoring wells on site and in two residential drinking water wells across the road from the Adams County Landfill site. However, no VOC contaminant plume has been defined. Health effects could occur if people were to drink groundwater that had site-related contaminants in it.
Cleanup ProgressIn March 1996, Illinois filed a state enforcement agreement between the State and the site potentially responsible parties (PRPs) that required the PRPs to conduct the design and construct the site cleanup actions. The enforcement agreement required the PRPs to install a barrier fence around the landfill, connect area residences with private drinking water wells to the public water supply, recap and regrade the landfill, install a leachate collection system, place deed restrictions on the property, and monitor the groundwater for chemical contaminants.
Illinois EPA approved the workplan to complete the design of the site cleanup actions in 1996 and, by the end of 1998, the PRPs had completed most of the construction work. Water service connections were made for five area residents. At present, work being conducted includes site security and monitoring of the leachate collection system, groundwater quality, and landfill cap integrity.
EPA conducted the first five-year review (FYR) at the Adams County Landfill site in 2003 and determined that site cleanup activities were satisfactorily operated and maintained and that all engineered remedies were functioning as designed. The FYR report concluded that potential short-term threats to human health and the environment had been addressed. Long-term protectiveness of the remedial action would be achieved when cleanup goals were met.
EPA conducted the second FYR at the Adams County Landfill site in 2008 and determined that site cleanup activities were satisfactorily operated and maintained and that all engineered remedies were functioning as designed. The FYR report concluded that potential short-term threats to human health and the environment had been addressed. Long term protectiveness required groundwater clean up standards to be met throughout the plume area and compliance with effective institutional controls (ICs) restricting land and groundwater use.
Following the 2008 FYR report, the PRPs submitted an ICs Study to EPA for review. EPA determined that it would be appropriate to incorporate the existing deed notices for the Adams County Landfill site into an environmental covenant prescribed under the Illinois Uniform Environmental Covenant Act (UECA). The UECA environmental covenant was recorded with Adams County on April 1, 2011.
EPA conducted the third FYR at the Adams County Landfill site in 2013 and determined that the site cleanup activities were satisfactorily operated and maintained and that all engineered remedies were functioning as designed. There is no known consumption of contaminated groundwater and no current exposure to the contaminants in the landfill. ICs are in place and effective.
EPA and Illinois EPA plan to complete the next FYR at the Adams County Landfill site by March 2018.
