Human and veterinary pharma- ceutical compounds are a source of increasing environmental concern because they are used in large quantities and their physical and chemical properties make them likely to be transported into hydrologic systems, where their effects on human health and aquatic ecosystems generally are unknown. The U.S. Geological Survey (USGS) and Centers for Disease Control and Prevention (CDC) began a study to determine the occurrence of selected pharmaceuticals in treated effluent discharged upstream of drinking-water intakes, in raw drinking water, and in finished drinking water in the upper Chattahoochee River watershed in Metropolitan Atlanta. Water samples were collected at 11 sampling sites once per month during low-flow conditions from July–September 1999. Two research analytical methods, recently developed or modified by the USGS Toxics Program, were used to quantify prescription and nonprescription pharmaceuticals, including antibiotics, at parts per billion (ppb) and sub-ppb concentrations in filtered water samples.
