The Ionia City Landfill, located on Cleveland Street, is a closed 20-acre landfill that operated from the mid-1930s until the late 1960s. The landfill accepted municipal, commercial, and industrial wastes which continued to be dumped through the 1970s. In 1981, the Michigan Department of Natural Resources confirmed the presence of volatile organic compounds (VOCs) in groundwater. The site was added to the United States Environmental Protection Agency’s (USEPA) National Priorities List (e.g., Superfund Site) in 1983. In 1985, exposed drums were excavated and removed from the site. The site was fenced and a clay cap was installed over the contaminated soil. The responsible parties entered into a legal agreement with USEPA in January 1986 to investigate the nature and extent of contamination at the site. The remedial investigation, completed in 1989, identified a one-quarter-acre area in the northern portion of the site containing approximately 6,000 cubic yards of drummed wastes and contaminated soils. Samples of the wastes in the drums revealed the presence of paint wastes and used solvents.
In 1989, USEPA issued a Record of Decision (ROD) which outlined the cleanup plan to address soil contamination; a second ROD was issued in 2000 to address groundwater contamination. In June 2022, 12 groundwater monitoring wells were sampled for PFAS and 1,4-dioxane. The highest groundwater result was 37.6 ppt of PFOS (compared to 16 ppt).
The Grand River runs along the site’s southern and western border, and groundwater flows southwest toward the river (see figure).
Drinking Water Information
EGLE, DHHS, and local health evaluated drinking water well logs and as of May 2023, no residential well sampling is planned. EGLE and DHHS will continue to monitor data.
EGLE will continue to work with EPA on additional sampling in the future.
