PFAS test results

Test results

The tables below show maximum results of our annual testing conducted for substances that have an Australian Drinking Water Guideline limit. Our current laboratory method enables us to monitor down to 0.002 micrograms per litre which remains well below the limits set by the Australian Drinking Water Guidelines. For comparison, 1 microgram per litre (µg/L) is equivalent to one part per billion.

2024 Maximum test results

For comparison, 1 microgram per litre (µg/L) is equivalent to 1,000 nanograms per litre (ng/L).
ND – no detectable concentrations. This is based on a limit of reporting for PFOA, PFOS, and PFHxS (the regulated PFAS) which is less than 0.002 micrograms per litre - well below safe limits.
