Short summary
The occurrence of pharmaceuticals was investigated in an urban aquifer that might be a resource for water supply. Among the 92 pharmaceuticals, 35 were detected in all groundwater samples, ranging from the low ng/L to 44.5 µg/L. The concentration of some substances decreased along the bank filtration, suggesting the occurrence of natural attenuation processes. Finally, risk quotients showed that these substances did not pose a risk to human health at groundwater measured concentrations.
