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.
Fundamental approach
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.
Contaminated site management - Step 1: Register
Registration of the polluted sites, initial assessment
Contaminated site management - step 2: preliminary investigation
The need for monitoring and remediation are clarified
Contaminated sites management - step 3: detailed investigation
The objectives and urgency of remediation are established
Contaminated sites management - step 4: remediation
The site has been remediated.
Monitoring and 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.
