Researchers Call for Stricter Testing
Independent researchers have discovered trace levels of PFAS in Adelaide’s tap water. These findings contradict SA Water’s statement that no detectable PFAS are present in their raw water supplies.
The University of Adelaide conducted a study, reported on April 12, 2026, which identified PFOS, PFHxS, PFOA, PFBS, and PFHxA in various locations in Adelaide’s CBD and suburbs. This research challenges SA Water’s testing methods, which only detect PFAS down to 2ng/L.
SA Water’s current testing does not detect PFAS levels below 2ng/L. By contrast, Sydney Water’s more stringent testing has identified PFAS thousands of times since 2024, at detection levels 20 times lower than SA Water’s limit.
Call for Enhanced Testing
Researchers recommend that SA Water implement a rigorous testing program, reducing detection limits to less than 0.1ng/L at treatment plant outlets and consumer taps. This would align with practices in other states like New South Wales and Queensland.
Trace levels of PFAS were found at all four CBD test locations and in residential areas, suggesting possible contamination from water pipes and infrastructure. The findings underscore the need for ongoing monitoring due to PFAS’s potential health impacts.
PFASs were detected in 100% of samples taken from a water fountain in an unspecified Adelaide CBD building. Four residential locations in suburban Adelaide showed similar findings.
The University of Adelaide’s study is the third of its kind, following research in 2010 and 2024. These studies emphasise the widespread presence of ultrashort-chain PFASs in Australian water systems and the importance of continued research and monitoring.
According to the University of Adelaide, exposure to PFAS chemicals, even in trace amounts, disrupts female fertility, causing cellular damage to ovulated eggs and embryos. This underscores the urgency for more stringent testing measures.
The contradiction between the new report and previous SA Water tests, which found no PFAS chemicals, highlights a critical issue with current detection methods. SA Water’s website states that PFAS testing has been conducted at 16 locations, all showing no detectable levels.
In light of these findings, experts urge SA Water to revise their testing protocols. Implementing more sensitive tests could prevent potential health risks associated with PFAS exposure.
The University of Adelaide’s research has prompted calls for policy changes at the state level. Authorities are encouraged to prioritise water safety and public health through better monitoring and infrastructure improvements.
