Background

The Amcast Industrial Corp. site is in the historic city and township of Cedarburg (Ozaukee County) in southeastern Wisconsin in a suburban residential area north of Milwaukee. Amcast was a local automotive industry supplier on Hamilton Road in Cedarburg.

The company first declared bankruptcy in 2004 and then again in 2005. The entire site consists of the Amcast facility, sewers near the former plant, a retention pond southeast of Amcast, a pond in nearby Zeunert Park, and some private properties to the southeast. Amcast had a plant that emptied PCBs into the creek via storm sewers. One of them emptied into Hamilton Pond, upstream of Green Bay Road. Due to heavy rains and high creek flow in 1996, the Hamilton Dam collapsed and was removed. The pond was drained leaving behind several acres of mud flats containing PCBs.

The sewers and soil under the building were sampled in November 2005. Since Amcast had filed for bankruptcy, its contractor was told to stop working and the results were never analyzed. Soil samples were also taken on private properties near the Amcast plant in summer 2005. Some of those samples showed PCB contamination slightly above what EPA considers to be safe levels.

The Amcast property investigation was originally being done as part of the Cedar Creek site. It came to a halt when the company filed for bankruptcy. EPA is committed to cleaning up Amcast and the surrounding area which is why they were combined to encompass one separate Superfund site.

What are PCBs?

PCBs, polychlorinated biphenyls, are toxic chemicals that were once widely used as industrial coolants, insulators and lubricants. PCBs can concentrate in the environment and the food chain, resulting in health hazards to people, fish and wildlife. Because of these dangers, the U.S. government banned the manufacture of new PCBs in 1976. PCBs still in use are strictly regulated.

Site Updates

February 2014

Results from soil samples taken on the Amcast property, as well as on nearby private properties between Hamilton Road and Wilshire Drive, are being reviewed by the EPA. This information will be detailed in a document called a remedial investigation report which should be available to the public this fall. In addition to taking samples on two areas referred to as the "north and south properties," EPA contractors focused on:

The remedial investigation report will be the basis for another document called a "feasibility study.” This study will examine several possible cleanup options as well as recommend one that appears to be the most appropriate. A proposed plan to clean up the Amcast property and surrounding private properties is expected to be available for public comment in 2015. A final cleanup decision will follow. All of these actions depend on the availability of federal funds.
