Tonsley and surrounding areas Groundwater Prohibition Area
Consultation has concluded
On 8 April 2021 the EPA established a groundwater prohibition area (GPA) in Tonsley and portions of Clovelly Park, Mitchell Park and Marion. These suburbs have a proud manufacturing history, with some past chemical disposal and handling practices having contaminated the groundwater.
If contaminated groundwater is a risk to human health, the EPA has the ability under the Environment Protection Act 1993 to establish a groundwater prohibition area. The purpose is to protect both current and future landholders from accessing the contaminated groundwater.
Before it made this determination, the EPA undertook a 90 day community consultation. All copies of reports, community updates and information is available from this website. If you can't find what you are looking for, or if you have any questions, please do not hesitate to let us know:
