Williamtown's treatment plant manages PFAS crisis but won't stop the leak
A treatment plant opened in March but Defence won't stop the leak by sealing contaminated sources.
Williamtown base has been Australia's benchmark PFAS contamination case for over a decade. Decades of firefighting foam soaked PFAS into soil under six areas of the base, and rain has carried it outward to Fullerton Cove.
Since March, a treatment plant on the base boundary has pumped one million litres per day of contaminated groundwater out of the ground. The plant manages the problem but does not end it.
Defence's own investigation found PFAS had soaked into the pavements at the source areas and would keep leaching. Pumping captures what has already left the site, not what is still being released from under buildings and pads.
New technology can now seal contaminated soil and lock PFAS in place. Over time this is cheaper than an open-ended pumping bill, yet Defence has not implemented it.
Residents south of the base have been waiting since 2015.

Why it mattersWithout source elimination, the treatment plant will run indefinitely and PFAS will keep spreading. Sealing the sources would give the crisis an actual end date instead of decades of pumping.
AustraliaResidents near Williamtown depend on tank water and ongoing remediation. A source-focused approach would shorten the contamination timeline and reduce long-term costs borne by Defence.
