Background
The Oconomowoc Electroplating Co., Inc. site is located in the unincorporated town of Ashippun, a rural area about 35 miles west of Milwaukee. It operated from 1957 to the early 1980s as an industrial facility that used metals, chemicals and organic compounds in its production process. During that time, the company discharged untreated wastewater into nearby wetlands and Davy Creek. Two unlined lagoons on the property contained electroplating sludge. These lagoons leaked and sometimes overflowed. Contaminants made their way into the ground water beneath and downstream of the site. (more...)

Site Updates
March 2012
EPA is doing a status review of the cleanup. This type of review is required at least every five years where the cleanup is complete but hazardous waste remains managed on-site. These reviews are done to ensure that the cleanup continues to protect people and the environment. This is the fourth five-year review for the Oconomowoc Electroplating Co., Inc. site.
Contact the site community involvement coordinator and/or the remedial project manager to provide input on this review process.
The review will include:
- An evaluation of background information
- Cleanup requirements
- Effectiveness of the cleanup and any anticipated future actions
- An analysis of ways for EPA to operate more efficiently
A report, which will be available by July, will detail the site's progress.
