Contaminated Sites

Contaminated Sites are defined under the Contaminated Sites Act 2003 (CS Act) as “having a substance present in or on land, water or a site at above background concentrations that presents, or has the potential to present, a risk of harm to human health, the environment or any environmental value”. Contaminated Sites in Western Australia are managed by the Department of Environment Regulation (DER). Under the CS Act, all land owners, occupiers and polluters are required to report all known or suspected contaminated sites to the DER, so that they can be assessed and classified, in consultation with the Department of Health (DoH), based on the risks posed to the community and environment.

All work undertaken by SWC is in accordance with the amended National Environmental Protection (Assessment of Site Contamination) Measure (NEPM) 2013 and the recently published (December 2014) Assessment and Management of Contaminated Sites (Contaminated Sites Guidelines) (DER, 2014).
