Test results
Keeping you informed on PFAS test results.
Riverina Water has proactively conducted testing since 2020 and all historic and current results are available below. The Australian Drinking Water Guidelines (ADWG) specify limits for PFAS substances.
Please note the Guidelines refer to safe levels in treated water. A detection in a raw water source does not necessarily indicate a detection in treated water.
In October 2024, the National Health and Medical Research Council proposed new health-based guideline values for PFAS substances that are currently undergoing consultation. Both guideline values are below for reference.
|
PFAS substance |
Existing ADWG level |
Draft proposed level |
|
PFOS |
70 ng/L or 70 parts per trillion (Less than 0.07 micrograms per litre of PFOS and PFHxS combined) |
4 ng/L. (Less than 0.004 micrograms per litre) |
|
PFHxS |
30 ng/L. (Less than 0.03 micrograms per litre) |
|
|
PFOA |
560 ng/L, or 560 parts per trillion. (Less than 0.56 micrograms per litre) |
200 ng/L. (Less than 0.2 micrograms per litre) |
|
PFBS |
1000 ng/L. (Less than 1.0 micrograms per litre) |
Results
- All results are below current and proposed Australian Drinking Water Guidelines health-based values unless otherwise specified.
- All results listed are ug/l, micrograms per litre.
- N/D means not detected.
