title: Occurrence of Antibiotics in Surface and Groundwater of a Drinking Water Catchment Area in Germany.
abstract: The contamination of the aquatic environment with organic micropollutants, such as veterinary pharmaceuticals, has become an increasingly serious problem and has aroused attention in the course of the last decades. This study presents a screening for a series of veterinary antibiotics, potentially introduced by the application of liquid manure, in ground- and surface water of a drinking water catchment in Lower Saxony, Germany. Of the 26 compounds analyzed, eight, including sulfadiazine, sulfapyridine, sulfamethoxazole, trimethoprim, dehydrato-erythromycin, sulfadimidine, tylosin, and tetracycline were detected in surface water samples. Trimethoprim was detected in 11 out of 15 shallow groundwater samples, indicating its high environmental relevance. Column sorption experiments conducted on trimethoprim show a comparatively moderate sorption affinity to sandy aquifer material with a retardation coefficient of 5.7.
