Study turned up Prozac, Valium in local water samples

A Miami Conservancy District study of the Great Miami River basin in 2010 and 2011 found low levels of 17 emerging organic wastewater contaminants — mostly pharmaceuticals and personal care products — at a variety of locations, including in the water discharged from wastewater treatment plants.

Low concentrations were also found in groundwater — from which Dayton pumps drinking water — though Conservancy District scientists say the levels were not sufficient to warrant concern about human health risks.

Still, scientists say increasing drug use could eventually result in more contaminants seeping into the water supply and in higher amounts. Here are the 17 contaminants found in the Conservancy District study:
