This research project realised a universal mathematical simulation for the entry of pharmaceutical active substance from surface water into groundwater via bank filtration. This information is required for the environmental risk assessment (ERA) within a marketing authorisation procedure of medicinal products for human use. Based on an extensive literature and data research a numerical model was developed considering both, the complexity of the process at the bank filtration site as well as the requirement for a user-friendly query mask for the determination of the Predicted Environmental Concentration in groundwater (PECgw). 

The result is a Microsoft Access based application in form of a input mask that will help to determine the expected concentration of a pharmaceutical active substance in groundwater (PECgw), based on the expected concentration of this substance in surface water (PECsw).
