The North Bronson Industrial Area Superfund site is located in Bronson, Michigan. The site is bounded by Lincoln Street as projected northward to County Drain #30 (CD #30), CD #30, Burr Oak Road as projected north to CD #30, and by Filmore and Union Streets. The site encompasses 220 acres, and is zoned by the city of Bronson for industrial use only. Land use in the larger area consists of a mixture of industrial, residential, and agricultural.
Contamination detected at the site is a result of industrial activity and waste handling practices in the North Bronson area since the early 1900's. Initially, several industries discharged plating and other industrial wastes directly into CD #30. To reduce the amount of contaminants entering the drain, the city of Bronson constructed seepage lagoons to retain the waste generated by industry. An industrial sewer system was also constructed and used to convey waste from the facilities to the lagoons. BPC is a company established in 1946 that performs nickel and chrome plating, buffing and polishing operations.
Two predominant features and contaminant source areas of concern are the two sets of lagoons located in the northeast and northwest sections of the site, just south of CD #30. CD #30 is the major surface water feature within the site and defines the northern site boundary. There are currently six outfalls discharging into CD #30 within the site boundaries. These include two BPC outfalls, the wastewater treatment plant outfall, the city of Bronson stormwater discharge, and two agricultural field outfalls on the north side of the drain. Private wells located within the site boundary and screened in the upper aquifer were found to be contaminated with site-related contaminants.
The Michigan Department of Environmental Quality (MDEQ) completed a Remedial Investigation (RI) of Operable Unit 1 (OU1) in September 1993 and a Feasibility Study (FS) for OU1 in May 1995. In July 1997 the MDEQ completed a FS Addendum. A Record of Decision (ROD) was issued in June 1998.
The selected remedy includes the following actions for Operable Unit 1 (OU1): excavate Eastern Lagoon (EL) contaminated soil and sludge; dredge contaminated sediment from County Drain (CD) #30; Consolidate contaminated waste from the ELs and CD #30 into the Western Lagoon (WLs); cover the WL area with an engineered soil cover; install a French Drain between the WLs and CD #30 to capture contaminated groundwater; construct a treatment wetland to treat contaminated water collected by the French Drain; pump contaminated water from the French Drain to the treatment wetland; discharge treated water to CD #30; monitor groundwater and surface water quality to assess the effectiveness of the remedy; install permanent warning markers or post signs; fence off the WL and wetland area; incorporate restrictions on land use through deed restrictions or local ordinances; restrict the use of contaminated groundwater through passage and implementation of local ordinances.
