Only few sulfonamide antibiotics were detected in near-surface groundwater in areas with a high stocking rate in northwestern Germany. Intensive sampling with a high resolution in time and space was applied in order to illuminate the findings. As some pharmaceuticals can be of both human and animal origin, they may enter the environment via application of manure/digestate to arable land or via domestic waste water. In addition to existing monitoring wells, non-permanent wells were sampled to obtain information regarding pathways into the ground water. Interviews with farmers and chemical analyses show that application of manure leads to low concentrations (<100 ng/l) of Sulfadimidin and Sulfadiazin in most of the investigated samples. Sulfamethoxazol was found above 100 ng/l and likely originated from sewage of nearby small scale wastewater treatment plants. Sulfamethoxazole and its main metabolite could be detected within the plants; additionally, the sewage tracer acesulfam-K was detected in the groundwater.
