The Ionia City Landfill is a closed 20-acre landfill in the city of Ionia, Ionia County, Michigan. The site is located in the flood plain of the Grand River and operated from the mid-1930s until it closed in 1968 or 1969. During operation mixed residential and industrial wastes, including drummed liquids and solids, were dumped and burned at the site. In 1981, the Michigan Department of Natural Resources confirmed the presence of volatile organic compounds (VOCs) in groundwater. Samples of the wastes in the drums revealed the presence of paint wastes and used solvents. 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. Approximately 6,000 people live within one mile of the site.
The site was proposed to the National Priorities List (NPL) in December 1982 and became final in September 1983.
In 1994, the potentially responsible parties removed 7,000 cubic yards of bulk waste, drums, and contaminated soil in and in 1995 groundwater pump and treatment system was implemented to contain the higher concentrations of VOCs in groundwater (underground water supplies). Construction of the extraction and treatment system was completed in November 1997 and is fully operational.
Since then, data has shown where the plume of contaminated groundwater is and that it is not impacting drinking water. Additionally, based on the data it appears that the full extent of the contaminant plume has been delineated and that monitored natural attenuation (MNA) is reducing some, if not all, of the remaining contamination.
As a result , in September 2008, EPA signed an Explanation of Significant Differences (ESD) for the site. The ESD outlined a plan to shut off the groundwater pumping system, helping to determine if MNA is naturally occurring at the site. The plan was to monitor the site for approximately one year and monitor the contaminant plume. Based upon studies conducted at the site it was determined that the Kanouse Drain was not connected to the aquifer at the site and that groundwater standards therefore did not apply to the Kanouse Drain.
EPA completed the second five-year review for the site in July 2010. The review indicated that the shutdown of the pumping system has had no negative impacts on reducing contaminants at the site.

Based on the pilot program from 2010, EPA recently completed a proposed plan detailng a new cleanup plan for contaminated ground water (underground water supplies).
EPA's cleanup recommendations include:
- Permanently turning off the treatment system and allowing natural processes to disperse the pollution. This method is known as "monitored natural attenuation" or MNA.
- Implementing long-term institutional controls such as deed restrictions or other limits on site reuse.
- Establishing a long-term ground water monitoring network that is sampled regularly to keep track of contaminant levels.
The estimated cost of the proposed cleanup is $750,000 over a 30-year period. The cleanup will protect people and the environment over the long-term, comply with state and federal regulations, can be implemented, and is cost-effective compared with the alternative of continuing the existing pump-and-treat ground water system at the landfill.
EPA invites comments on this proposed plan at a public meeting on Thursday, July 21, 2011, 6:30 p.m., at Ionia City Hall, Council Chambers, 114 N. Kidd St.
