"Setback distances between small biological wastewater treatment systems and drinking water wells against virus contamination in alluvial aquifers";
Science of the Total Environment, 573 (2016), 15. Dec.; S. 278 - 289.



Kurzfassung englisch:
Contamination of groundwater by pathogenic viruses from small biological wastewater treatment System discharges in remote areas is a major concern. To protect drinking water wells against virus contamination, safe setback distances are required between wastewater disposal fields and water supply wells. In this study, setback distances are calculated for alluvial sand and gravel aquifers for different vadose zone and aquifer thicknesses and horizontal groundwater gradients. This study applies to individual households and small settlements (1-20 persons) in decentralized Locations without access to receiving surface waters but with the legal obligation of biological wastewater treatment. The calculations are based on Monte Carlo simulations using an analytical model that couples vertical unsaturated and horizontal saturated flow with virus transport.
