WaterNSW has temporarily closed Medlow Dam in the Blue Mountains after detecting elevated PFAS levels in untreated water, disconnecting it from the supply network for safety.
The water supplied to communities by the Cascade water filtration plant is confirmed safe to consume and adheres to Australian drinking water standards, despite concerns around PFAS.
Despite the presence of PFAS at Medlow Dam, an expert panel reports no current evidence linking these chemicals to an increased overall cancer risk.
Testing revealed PFOS and PFHxS levels in untreated water at Medlow Dam to be slightly above the threshold set by Australian drinking water guidelines.
