Soil protection

Soil protection concerns both chemical contamination and physical degradation such as erosion, compaction and sealing by construction. In Switzerland, it protects fertile soil as a limited natural resource and regulates excavation, disposal, contaminated sites, agricultural practices and construction impacts. Authorities may require investigations, protective measures, remediation or careful handling of excavated soil. The field overlaps with spatial planning, agriculture, waste law and groundwater protection. Legal questions often involve historic pollution, allocation of cleanup costs, thresholds for reuse of soil material and balancing development needs with preservation of productive land.
