3700 MILHAM ROAD

The Roto-Finish site is a 7-acre site located in Portage, Kalamazoo County, Michigan. Roto-Finish manufactured equipment to debur and polish metal and plastic castings, mechanical parts and other objects at the site from 1950 until 1988. Prior to 1980, Roto-Finish discharged wastewater from the manufacturing processes to drywells and three lagoons. In 1979, the Michigan Department of Natural Resources (MDNR) sampled two of the lagoons and detected amines, phenols, metals, and 4,4-methylenebis (2- chloroaniline). In 1980, Roto-Finish closed the lagoons and dry wells and rerouted all waste discharges to the municipal sewer system. Groundwater contamination extends from Roto-Finish to about one-half mile northwest-west of the site. Approximately 45,000 to 50,000 people live within three miles of the site. The aquifer provides drinking water to an estimated 100,000 residents. Municipal water supply wells and private wells may still exist within one mile of the site. Site Responsibility This site is being addressed through federal, state and potentially responsible parties' actions.
