Site DescriptionPrior to 1966, the 30-acre Industrial Excess Landfill (IEL) site, located in Stark County, Ohio, was used for mining sand and gravel. In 1966, the mining and excavation pit was converted into a landfill, which operated until 1980. During this time, the IEL received industrial waste primarily from the rubber industries in Akron, Ohio. An estimated 780,000 tons of solid waste and 1,000,000 gallons of liquid waste were dumped onto the ground and into an evaporation lagoon constructed onsite. In 1972, the Stark County Board of Health ordered IEL to stop dumping chemical wastes. Besides industrial wastes, the landfill also accepted waste from hospitals, septic tank cleaning firms, and the general public. The landfill ceased operations in 1980, and was covered with soil. According to the 1990 Census, 27,121 people live within a three-mile radius of the site, including 3,912 children below the age of nine years.
Site ResponsibilityThis site is being addressed by responsible party actions, with oversight by U.S. EPA and Ohio EPA.
Threats and ContaminantsOn-site groundwater is contaminated with a few volatile organic compounds (VOCs). Contamination levels are decreasing, both in terms of number of contaminants detected and in concentration. There is no evidence indicating the presence of a groundwater plume. Methane concentrations in the landfill gas continues to dissipate, to the point where the existing methane venting system is shut down.
Most residents downgradient of the site are connected to an alternate water supply, thereby minimizing potential receptors of contaminated groundwater from the site. Although historically there have been sporadic detections of metals outside of the landfill boundaries, tests of drinking water wells in 1998 revealed that such metal contaminants were significantly lower (i.e., one or two orders of magniture less) than federal drinking water standards.
Between 1985 and 1988, the United States Environmental Protection Agency (U.S. EPA) installed a methane gas venting system at the site to control the migration of methane and landfill gases offsite. During the installation of this system, 53 drums of suspected industrial waste were uncovered. These drums were removed and disposed of in a U.S. EPA-approved facility. Residential well sampling performed in 1987 showed that private wells were being impacted by groundwater contaminated by VOCs. U.S. EPA installed air strippers in the affected residences to remove the contaminants.
In 1987, U.S. EPA signed a Record of Decision (ROD) that required the installation of an alternate water supply in an area containing 100 homes downgradient of the site. Under order by U.S. EPA, several potentially responsible parties (PRPs) completed construction of the alternate water supply in 1991. In July 1989, U.S. EPA signed a ROD selecting the following actions to clean up the site: cover the entire site with a multi-layer cap; expand the landfill gas extraction and treatment system; extract and treat contaminated groundwater; pump groundwater to maintain the water table at a level that is below the wastes in the landfill; fence the site; place deed restrictions on the future use of the site, and continued monitoring of the site. In 1990, U.S. EPA purchased 22 parcels of land, consisting of twelve residences and two businesses. These properties, which bordered the site, were needed for proper installation of the landfill cap.
Based on monitoring data EPA signed a ROD Amendment on March 1, 2000 that eliminated the pump and treat system and redesigned the landfill cover. In June 2000, the PRPs conducted demolition of three remaining buildings at the site, along with removal of eight underground storage tanks.
In late October 2000, in response to a petition from stakeholders in the IEL area, the U.S. EPA Ombudsman issued preliminary recommendations regarding radiation sampling at IEL. The Ombudsman issued a final report in September 2005, which found that U.S. EPA used appropriate sampling and analysis methods to look for potential radioactive contamination at IEL and that it was unlikely that radioactive contamination was present.
On September 27, 2002 EPA signed a second ROD Amendment, based on additional groundwater surveys conducted by the PRPs in 2000 and 2001. The ROD amendment included the following components: 1) augmentation of the existing vegetative cover at IEL with selective planting of trees and other plants at the site; 2) natural attenuation of groundwater contaminants both offsite and onsite; 3) continued monitoring of groundwater and landfill gas; 4) perimeter fencing; 5) deed restrictions on the future use of the IEL property; 6) maintenance of the alternate water supply installed in 1991; and 7) additional design studies.
Construction of the IEL final remedy began in Spring 2004. By August 2004, all of the new groundwater monitoring wells were installed and unnecessary wells had been abandoned. In addition, planting of the site vegetative cover was completed in May 2004. Continued groundwater monitoring shows that VOC concentrations in groundwater continue to decrease and that only three contaminants now exceed their MCLs. A third five year review was completed in May 2011. It concluded that the remedy at the Site is protective of human health and the environment in the short term, and the long term protectiveness will be achieved when: proper maintenance of the perimeter frence and monitoring wells is conducted; the cleanup goals for the contaminated groundwater have been reached; and stewardship measures are put in place for the implemented institutional controls.
The potentially responsible parties continue to inspect the site and collect samples from groundwater monitoring wells twice a year. U.S. EPA will conduct the next five-year review for the site in 2016.
Community InvolvementCommunity interest in the landfill remains high.
The resuse plan for the site includes construction of a walking path around the perimeter of the landfill fence. Lake Township has recently expressed interest in commercial development of property adjacent to the landfill. There is no current plan for reuse of the landfill property that would allow public access to the landfill itself.
