"Today’s news coverage reports potentially unsafe levels of “forever chemicals”
detected in drinking water supplies around Australia. These include human-made
chemicals: perfluorooctane sulfonate (known as PFOS) and perflurooctanic acid
(PFOA). They are classed under the broader category of per- and polyfluoroalkyl
substances or PFAS chemicals.
The contaminants found in our drinking water are the same ones United States
authorities warn can cause cancer over a long period of time, with reports
warning there is “no safe level of exposure”.
In April, the US Environmental Protection Agency (USEPA) sent shock waves
through the water industry around the world when it announced stricter advice
on safe levels of PFOS/PFOA in drinking water. This reduced limits considered
safe in supplies to zero and gave the water industry five years to meet legally
enforceable limits of 4 parts per trillion.
So, should the same limits be enforced here in Australia? And how worried
should we be that the drinking in many parts of Australia would fail the new US
standards?"
