Don’t Flush! Scientists say unused prescription drugs are hurting Great Lakes

Helen Domske, with Sea Grant New York, says unused prescription drugs are often dumped down the drain or the toilet. That means antibiotics, hormones and vitamins are making their way into our waterways, threatening marine life.

Prescription drugs are contaminating Lake Michigan two miles from Milwaukee’s sewage outfalls, suggesting that the lake is not diluting the compounds as most researchers expected, according to new research.

“In a body of water like the Great Lakes, you’d expect dilution would kick in and decrease concentrations, and that was not the case here,” said Dana Kolpin, a U.S. Geological Survey research hydrologist based in Iowa.

It is not clear what, if any, effects the drugs are having on fish and other creatures in Lake Michigan. But this ability to travel and remain at relatively high concentrations means that aquatic life is exposed, so there could be “some serious near-shore impacts,” said Rebecca Klaper, an associate professor at the University of Wisconsin-Milwaukee and senior author of the study published in the journal Chemosphere.
