Information about Mercury Marine Corporation

Information about the Cedar Creek Site

The Cedar Creek Site is located in Cedarburg, Wis. a suburban residential area north of Milwaukee. The entire site consists of Mercury Marine's Plant 2 and the segment of Cedar Creek from below the Ruck Pond dam to the point where it meets the Milwaukee River. This segment includes open stretches of creek as well as areas known as Columbia Pond, Wire and Nail Pond, and the former Hamilton Pond for a total of 5.1 creek miles.

Polychlorinated biphenyls (PCBs) from Mercury Marine's boat manufacturering operations contaminated Cedar Creek and the Plant 2 property. Mercury Marine operated a plant on St. John Avenue from 1951 to 1982. Fluids, containing PCBs, leaked from equipment and were washed into floor drains. These drains emptied into storm sewers, which emptied into Ruck Pond and flowed into the Milwaukee River.

Mercury Marine's Plant 2 building was demolished in May 2005. The building, which was in poor condition, also contained PCB contamination. An investigation and feasibility study outlining possible cleanup options was completed in October 2007. A decision on how to clean up Plant 2 was made in March 2008.
