Key facts
The Swiss Federal Audit Office (SFAO) conducted an audit at the Federal Department of Defence, Civil Protection and Sport (DDPS) that focused on the handling of contaminated sites. The Cadastre of contaminated sites of the DDPS provides a nationwide overview of the sites that are within its area of enforcement and are considered to be contaminated without harmful effects or nuisances under the Contaminated Sites Ordinance (CSO), or for which an investigation must be carried out to determine whether they are in need of monitoring or remediation.
