Transport and Attenuation of Pharmaceutical Residues During Artificial Groundwater Replenishment

Transport and Attenuation of Pharmaceutical Residues During Artificial Groundwater Replenishment Environmental Context.

Abstract

Environmental Context. The contamination of public water supplies by drug residues is an issue of importance for public health. While soil may act as a natural filter to remove some contaminants from groundwater, there is a lack of information on the fate and transport of pharmaceutical residues during groundwater recharge. In this study, the fate and the transport of eight drug residues during groundwater recharge of contaminated surface water which was investigated at an artificial groundwater replenishment plant in Berlin, Germany, as part of the international collaboration NASRI (Natural and Artificial Systems for Recharge and Infiltration). The study shows that some of the contaminants would indeed end up in the water supply if the water only underwent normal groundwater recharge. Abstract. Recently, several new types of organic contaminants such as pharmaceuticals and their metabolites have been found in sewage or surface waters. Some of the polar pharmaceuticals have also been detected in samples of ground and drinking water, especially when water from induced recharge is used for drinking water production. The fate and the transport of eight drug residues during groundwater recharge (GWR) of contaminated surface water was investigated at an artificial groundwater replenishment plant in Berlin, Germany. After a recharge distance of only a few meters, bezafibrate, a blood lipid regulator, and indomethacin, an analgesic, were removed below their detection limits. Clofibric acid, a metabolite of blood lipid lowering agents, and the analgesic drugs diclofenac and propyphenazone were also attenuated during GWR. However, they were still detectable in the receiving water supply wells at low concentration levels (≤ 40 ng L –1 ).
