Groundwater discharges of biocides from façades in urban regions

Description: Biocides, commonly used in building materials, are released through precipitation and can contaminate the groundwater. The study evaluates the transport of biocides through urban pathways — vegetated soils, permeable pavements, and infiltration systems — and gives recommendations for refining the European ⁠ Emission ⁠ Scenario Documents (ESD). The aim is to enhance groundwater protection in urban areas, advocating for the use of biocide-free materials and sustainable rainwater management as part of broader blue-green infrastructure strategies. The results provide an important basis for architects, engineers, and municipalities, promoting sustainable construction practices to reduce biocide emissions. Veröffentlicht in Texte | 133/2025.
