"The Minnesota Pollution Control Agency is proposing to add more lakes and streams to the state's list of impaired waters.

As the MPCA continues testing water bodies across the state, more are being added to the list due to water quality problems such as excess nutrients, mercury, salt and bacteria.

Under the federal Clean Water Act, Minnesota must update its list of impaired waters every two years. About 40 percent of Minnesota's lakes, rivers and streams do not meet water quality standards."
