NPL Site Narrative for U.S. Aviex

Howard Township, Michigan

Federal Register Notice:  September 08, 1983

Conditions at listing (December 1982): The U.S. Aviex Co. Site covers 2 acres in Howard Township, Cass County, Michigan. The company produces various automobile solvents. In 1972, several residential wells southwest of the plant were contaminated with ether from a leaking transmission line on-site. The line was repaired, and the company replaced three wells. In November 1978, fire destroyed most of the facility and released a number of organic compounds into the soil and ground water. Dichloromethane, benzene, toluene, and other chemicals were detected in nearby residential wells. In early 1982, the State filed suit against the company. The court ordered U.S. Aviex to conduct a pump test in preparation for possible purging and treatment of contaminated ground water.

Status (July 1983): U.S. Aviex completed the court-ordered test in spring 1983 and has begun purging operations.
