Tweed tap water passes PFAS safety testing with flying colours
Tweed tap water passes PFAS safety testing with flying colours
Independent lab results confirm Tweed’s drinking water remains fully compliant and safe to drink
By Robert Heyward
Independent laboratory testing has confirmed that tap water in the Tweed Shire remains safe to drink and is well below both current and proposed limits for PFAS (per- and polyfluoroalkyl substances), as outlined by the Australian Drinking Water Guidelines (ADWG).
This testing, conducted in October 2024, followed a recommendation by NSW Health for all water authorities in the state to test for PFAS levels in treated drinking water.
Rigorous Testing Across Tweed’s Water Systems
Samples were collected by trained Tweed Shire Council staff from the region’s three water supply systems:
- Tweed District (Bray Park Water Treatment Plant)
- Uki village
- Tyalgum village
The samples were sent to the accredited Sydney Water Laboratory Services for independent testing.
Results Overview
Council’s Manager of Water and Wastewater Operations, Brie Jowett, confirmed that the testing showed undetectable or extremely low levels of key PFAS substances:
- PFOA:
- Measured at 0.1 ng/L in Tweed District systems.
- Below 0.1 ng/L in Uki and Tyalgum systems (minimum detectable limit).
- ADWG limit: 560 ng/L.
- PFOS and PFHxS:
- Below 0.1 ng/L (minimum detectable limit) across all systems.
- ADWG limit: 70 ng/L.
- PFBS:
- Found at levels below 0.5 ng/L (minimum detectable limit).
- No current ADWG limit, but the levels are considered very low and well within expected safety standards.
Safe Now and Into the Future
The National Health and Medical Research Council (NHMRC) is currently reviewing the Australian Drinking Water Guidelines, with proposed lower limits for PFAS substances and a new guideline for PFBS expected to be finalised in 2025.
Ms. Jowett assured the community that Tweed’s tap water would remain safe even if these stricter guidelines are introduced:
“The Tweed’s tap water is currently safe to drink and will continue to be safe under the draft Australian Drinking Water Guidelines. These results highlight our commitment to providing safe, healthy water for the long term.”
About PFAS
PFAS substances, used globally since the 1950s, are not manufactured in Australia but are present in many industrial and consumer products, such as:
- Firefighting foams
- Pesticides and fertilisers
- Carpets and paints
- Non-stick cookware and food packaging
- Clothing and personal care products like sunscreen and make-up
While PFAS is not added to drinking water, trace amounts may enter water sources due to environmental contamination.
