A Scientist Working in a Laboratory Measuring Pharmaceuticals in Water

A PhD fellow from the University of York measuring pharmaceutical concentrations in samples collected from the Rivers Foss and Ouse, United Kingdom, during her work at the U.S. Geological Survey (USGS) National Water Quality Laboratory. A new study evaluated if predicted environmental concentrations of pharmaceuticals (based on pharmaceutical usage data, degree of metabolism in humans, removal in wastewater treatment plants (WWTPs), and environmental dilution), reflect actual measured environmental concentrations in two stream systems of different sizes and demographics.
