GM to complete independent testing of Rock River contamination

General Motors will hire an engineering firm to perform additional sampling to determine the level of contamination in the Rock River and possible causes, a spokeswoman said.

Janesville city officials announced last week that contaminants were found during a routine sediment analysis that was part of a study to determine the future of the Monterey Dam.

GM spokeswoman Sharon Basel said the final report will be provided to the Wisconsin Department of Natural Resources and the city of Janesville.

Basel said GM is taking the situation seriously and its role in community with the DNR has already started, but the city’s report is just a draft, and it has not been confirmed that GM is responsible for the contamination.

She said the company plans to start its evaluation Feb. 1 and have a final report by the spring.

DNR officials said there is no immediate risk to public health from fish consumption or direct contact.
