On 19 August 2020, the EPA was notified of test results in soil collected at the former Port Adelaide Waste Water Treatment Plant, and in groundwater monitoring bores offsite that are located in reserves and other public land. The results showed per- and poly- fluoroalkyl substances (PFAS) above relevant guidelines.
The EPA advises that groundwater (bore water) in the West Lakes assessment area is contaminated and should not be used for any purpose.
Lake water, tap water and rainwater are not affected.
Previous work undertaken by the EPA has included a program to sample the lake water, groundwater, fish and crustaceans. These reports are available from the document library on this site.

Hello Dee
Thank you for your question, and thank you for sharing it here so others can also see it and the response.
The community engagement area shown on the map is approximately 700 homes, and is the distribution boundary for the community update. The number of properties impacted by sludge is just under 200 properties, and these have not been identified for the protection of the privacy of those residents.
All residents who are impacted have been sent a letter that outlines their specific situation in addition to this community update, and have been provided with a copy of the report on the work undertaken in 2001 by the state government (where this offer was accepted).
I hope that clarifies your query - please don't hesitate to let us know if there's anything else we can help you with.
