Abstract |
The 13-acre Algoma Municipal Landfill site is an inactive municipal landfill in Algoma, Kewaunee County, Wisconsin. The site overlies an aquifer that currently supplies water to private wells. Solvents, thinners, lacquers, as well as municipal wastes were reportedly disposed of in the main landfill area known as the Landfill Disposal Area (LDA). Approximately 400,000 cubic yards of municipal wastes were disposed of at the site. In 1983, the landfill was closed and the wastes were covered. However, over time, the cap has deteriorated due to weather and lack of protection from freezing and thawing. Therefore, the current cover has not been impermeable and landfill contaminants have been released into the ground water. EPA site investigations conducted in 1984 and 1989 revealed onsite ground water contamination caused by sources leaching from the LDA. The Record of Decision (ROD) addresses the remediation of contaminated source and ground water. The primary contaminants of concern affecting the ground water, soil, and debris are VOCs including benzene; other organics; and metals including arsenic and cadmium. |
