The competent district administrative authority can provide you with information regarding sites suspected of being contaminated or confirmed contaminated sites. These are sites that, due to harmful soil changes as defined by the Federal Soil Protection Act, may pose a risk to humans or the environment.
Sites suspected of being contaminated may include, for example, former landfill sites (old landfills) and properties formerly used for industrial or commercial purposes (former industrial sites) where environmentally hazardous substances were handled.
You can access initial information on sites suspected of being contaminated as well as confirmed contaminated sites online via the public portal “ABuDIS – Contaminated Sites, Soil Protection, and Data Information System.”
For detailed information on contaminated sites, please contact the district administrative authority responsible for your area.
Regional Supplement (Editorial Responsibility: City of Erlangen)The city of Erlangen maintains a contaminated sites registry that lists sites with known soil contamination as well as sites where such contamination is suspected. These include, for example: industrial sites, facilities where water-polluting substances were handled, auto repair shops, gas stations, dry cleaners, old landfills, waste storage sites, and others.
The disclosure of the information must not conflict with any legally protected interests of others.
