Water
Health of our local rivers
The rivers of the Southern Highlands flow into Warragamba, supplying drinking water to 5 million people in Sydney. What's in them matters to all of us.
What the platypuses are telling us
Forever chemicals in our catchment
When Dr Ian Wright's research team started testing dead platypuses for PFAS contamination, the lab manager called immediately with an urgent question: “Where is this from?”
The third most contaminated platypus in NSW was found in the Wingecarribee River at Berrima, which flows directly into the Warragamba catchment that supplies Sydney's drinking water. PFAS is harmful at concentrations so dilute they defy intuition (nanograms per litre), and it builds up in our bodies just as it does in platypus tissue.
WinZero is raising awareness of pollution in our rivers, hosting public forums with local scientists, and supporting community testing.
