Results of recent testing of fish (redfin, eel and carp) from Morwell’s Kernot Lake by Environment Protection Authority Victoria (EPA) has confirmed high levels of PFOS (perfluorooctane sulfonate), one of the PFAS (per- and poly-fluorinated alkyl substances) family.
EPA has confirmed its previous advice to the public not to eat fish caught there.
PFAS are a group of man-made chemicals, many which have been in common use for many decades, including in historic firefighting foams and in-home products like non-stick pans and carpet treatments.
As the use of PFAS is widespread and the chemicals are slow to break down, traces of PFAS are likely to be found in groundwater, surface water and soils in many urban areas.
While there is still no consistent evidence of the relationship between concentrations of PFAS in the environment and food and specific illness in humans, they can persist in humans for many years. EPA takes a standard, precautionary approach that minimises risk and recommends against consumption of animal products or water where PFAS levels are considered high.
Samples indicated elevated levels, which has now been confirmed.
EPA's Chief Environmental Scientist, Dr Andrea Hinwood, said “Our analysis showed, in December last year, that PFAS levels appeared high containing levels of PFAS above drinking water concentrations.”
“Following testing of fish taken from the Lake in January this year, EPA has confirmed its previous advice not to consume any fish caught in Kernot Lake.”
“To protect the community, EPA is taking a precautionary approach to PFAS working to minimise the risks of exposure to products and water containing elevated PFAS levels.”
