METAL WORKING SHOP

EPA ID# MID980992952
Last Updated: August, 2010

Site Description

The Metal Working Shop site covers approximately two acres on a hill between Lake View and Lake Ann. From 1974 to 1977, the owner of the property finished metals in the shop, using iron phosphate. Two types of rinse waters were generated in an oxidizing phase of the operation: an acidic rinse (diluted hydrochloric acid), containing iron phosphate, and a caustic rinse (sodium hydroxide). From 1975 to 1977, effluents from these rinses were mixed to neutralize them and then they were dumped onto the ground. According to the owner, 400 gallons per day were disposed of for 8-10 days per month. In 1983, Lake Ann Manufacturing took over the site. Sampling by the state detected heavy metal salts in the rinses. Groundwater in the area occurs at shallow depths, and wells draw from the very permeable sand and gravel drift aquifer. The area residents depend on private wells for drinking water. Approximately 1,000 people reside within three miles of the site, and the nearest residence is 600 feet away. Many other lakes are located within three miles of the site. 

The United States Environmental Protection Agency (EPA) placed the site on the National Priorities List in February 1990.

Site Responsibility

This site was addressed through federal actions.

Threats and Contaminants

The groundwater and soil were believed to be contaminated with low levels of volatile organic compounds. However, extensive sampling conducted by the United States Environmental Protection Agency (EPA) revealed no contamination above natural levels. Because contamination levels were very low and the site contaminants were not migrating, no threat to the public or the environment existed. 

Cleanup Progress

In 1992, EPA completed an investigation to determine the nature and extent of contamination, including sampling of monitoring wells, residential wells, surface and subsurface soils, and lakes. The investigation results showed that the concentration of contaminants at the site did not pose a threat to public health or the environment. Therefore, EPA determined that no cleanup actions were necessary and deleted the site from the National Priorities List (NPL) on December 23, 1992.

Property Reuse

In 2000, the site was purchased by a camp.  While a majority of the site is designated as forest, a small portion is being used for woodworking.
