Publisher's Synopsis
Samples of treated effluent and treated and untreated water were collected at 20 municipal wastewater and drinking-water treatment facilities in the Tar and Cape Fear River basins of North Carolina during 2003 and 2005. The samples were analyzed for a variety of prescription and nonprescription pharmaceutical compounds and a suite of organic compounds considered indicative of wastewater. Concentrations of these compounds generally were less than or near the detection limits of the analytical methods used during this investigation. None of these compounds were detected at concentrations that exceeded drinking-water standards established by the U.S. Environmental Protection Agency. Bromoform, a disinfection byproduct, was the only compound detected at a concentration that exceeded regulatory guidelines.
