The Contaminated Sites Act 2003 was introduced to identify, record, manage and clean up contamination.
Under the Act, known or suspected contaminated sites must be reported, investigated and, if necessary, cleaned up (remediated).
The Contaminated Sites Database records information on sites classified:
- contaminated - remediation required
- contaminated - restricted use
- remediated for restricted use
All other reported sites, including those awaiting classification, are recorded on the Reported Sites Register (not available online).
