Contaminated sites
|
Western Australia's contaminated sites legislation aims to protect people's health and save the environment from harm. Under the Contaminated Sites Act 2003, contaminated sites must be reported to DEC, investigated and, if necessary, cleaned up. Reporting sites to DECLand owners, occupiers and polluters are required to report all known or suspected contaminated sites (Form 1) to the Department of Environment and Conservation (DEC). Reported sites are classified, in consultation with the Department of Health, based on the risks posed to the community and environment. New: Interim guidance note

New: DEC's interim guidance note
relating to the recent release of CRC CARE's guidance on Health screening levels (HSLs) for petroleum hydrocarbons in soil and groundwater.
In addition to considering the HSLs, environmental consultants must also take into account groundwater usage, aesthetic concerns and ecological risks in all site assessments. The HSLs should be used in conjunction with DEC's guideline, Assessment levels for soil, sediment and water, 2010. |
