A new study offers an explanation to the mystery of why pharmaceuticals and other chemicals are found in remote Minnesota lakes, far from developed land that would create contaminated runoff.

”These chemicals such as antibiotics, and anti-corrosives and endocrine active chemicals were being found in lakes where we might not expect them because there was no surrounding development,” said Mark Ferrey, a Minnesota Pollution Control Agency scientist who, in search of an answer, collected snow, rain and air samples at three locations in the Twin Cities and had them tested for 126 chemicals.

Ferrey found 17, including DEET, cocaine, antibiotics, an anti-corrosion chemical, an x-ray contrast chemical and the pain reliever naproxen.
