Minnesota researchers found 56 chemicals — including cocaine — in the state’s waters, according to two studies released today that raise questions about potential impacts on wildlife and human health.

The chemicals were detected at trace amounts in 47 of 50 Minnesota lakes, including many in relatively pristine parts of the state.
