The fate and transport of 26 common human and veterinary antibiotics, four anti-inflammatories (ibuprofen, diclofenac, ketoprofen, and naproxen), the anti-epileptic drug carbamazepine, and a widely-used X-ray contrast agent, iohexol, in a small, urban watershed that is impacted by wastewater discharges from three communities that include major hospitals, several large residential nursing homes, and several research centers. The watershed ultimately links an impacted reservoir to a downstream drinking water source, and the levels of these pollutants in the aqueous phase have been evaluated in order to begin a comprehensive ecological risk assessment associated with residual pharmaceutically active compounds in surface waters. Includes 11 references, table, figures.
