The Contaminated Sites Act 2003 (Act) provides a regulatory scheme for dealing with sites that are known or suspected to be contaminated. Among other things, the scheme involves reporting, investigating and remediating such sites.

One feature of the scheme is that an accurate database of WA’s contaminated sites is kept by the Chief Executive Offi cer (CEO) of the Department of Environment and Conservation (the DEC). Information for the database is obtained (primarily) from persons who now have a statutory duty to report known, or suspected, contaminated sites to the DEC.

Additionally, any member of the public who is concerned that a site is, or may be, contaminated may voluntarily lodge a report.
