Abstract:  The Roto-Finish Company site is an inactive manufacturing facility located in Portage, Michigan. The site covers approximately 7 acres and is in an area directly east of the Kalamazoo/Battle Creek International Airport. Other industrial activities in the area include plastic color pigment manufacturing, a building supply business, garment retailing distribution, surgical supply manufacturing and warehousing, plastics manufacturing, and pharmaceutical research and manufacturing.The Roto-Finish Company manufactured specialized equipment to debur and polish metal castings, mechanical parts, and similar objects that required smooth finishes. Manufacturing operations at the site began in the late 1940s to early 1950s and continued until 1988, when the business was sold and the facilities were closed. There are two buildings at the site: the manufacturing building and the chip and compound building. The manufacturing building housed offices and areas used for equipment manufacturing, testing, and storage. The chip and compound building was used for the production and storage of the polishing media used with the manufactured equipment. Roto-Finish used two systems for waste disposal. The waste from the rest rooms and other non-processing and laboratory wastes were disposed of through a system of septic tanks, dry wells, and a tile field. The waste water generated from the manufacturing and testing processes was discharged to three lagoons. The lagoons were located near the eastern boundary of the property, along the east and north sides of the chip and compound building. The wastewater was discharged to the lagoons until 1980, when the facility was connected to the municipal sanitary sewer system. During this same time the facility was connected to the municipal water supply, and the water supply wells at the site were disconnected and are inoperable.In 1979, the Michigan Department of Natural Resources analyzed water samples from the wastewater lagoons on site and a variety of contaminants were found. Between 1979 and 1984, the lagoons and areas of visibly stained soils were excavated and disposed of in an off-site landfill. The excavated areas were backfilled with clean material. The site was placed on the National Priorities List (NPL) in 1986.
Remedy:  The selected remedy addresses the risks posed by potential future exposure to contaminated groundwater, and to restore the contaminated aquifer to its potential future use as a supply of municipal, residential, and industrial drinking water. The major components of the remedy are natural attenuation, institutional controls, monitoring program, maintaining the existing groundwater extraction system, and developing contingency plans.
