Altlastenverzeichnis

Altlastenverzeichnis is a register used in Germany to document historically contaminated sites. It records locations where soil or groundwater contamination is suspected or confirmed due to previous industrial activities, waste disposal, mining, or chemical use. The repository is typically maintained by municipal authorities or by state environmental agencies, and it serves as a planning and risk management tool.

Entries usually contain the site name and address, the former land use, known or suspected pollutants, the assessed level of hazard, any investigations conducted, and the current remediation status or planned measures. The purpose is to support spatial planning, land recycling, and public safety by enabling authorities to identify critical areas, inform developers, and prioritize remediation.

Legal framework: Under the German Federal Soil Protection Act (BBodSchG) and related state laws, authorities identify and document contaminated sites and may require investigations. The Altlastenverzeichnis is often complemented by site-specific reports and by maps or databases (Altlastenkarte) used in planning. Data access may vary; some information is public, while more detailed data can be restricted.

Limitations: Not all contaminated sites are recorded; new information may lead to updates; some entries may reflect historical knowledge with uncertain status. The register does not substitute for site-specific risk assessments or regulatory decisions.
