Remediation of contaminated sites

A large number of polluted sites can only be handled in steps for reasons of personnel, time and money. In principle, individual sites should be approached first at a global and then at an increasingly detailed level in order that those among the approximately 38'000 polluted sites requiring remediation or monitoring can be earmarked.

Stand der Bearbeitung

Die Kataster der belasteten Standorte von Bund und Kantonen sind fertiggestellt und im Internet abrufbar. Total bestehen rund 38‘000 belastete Standorte, wovon ca. 4'000 sanierungsbedürftig («Altlasten») sein dürften. Über 1'500 Altlasten sind bislang saniert worden.

Management

The costs of tackling contaminated site issues in an unsystematic way can easily escalate. To avoid this problem, it is advisable to proceed according to the scheme described below.

Register

Registration of the polluted sites, initial assessment

Preliminary investigation

The need for monitoring and remediation are clarified

Detailed investigation

The objectives and urgency of remediation are established

Remediation

Monitoring, aftercare

Key elements of contaminated sites remediation

Cooperation

Complex tasks such as remediation can only be tackled if all parties work toward the solution, which is stated by the Contaminated Sites Ordinance.

Shooting ranges

The investigation, monitoring and remediation of bullet traps at shooting ranges often raise issues regarding procedure, objectives and appropriate measures as well as the financial impact and scientific basis.
