Moorabool Water Treatment Plant – Supplies about 90,000 residents in Geelong area with drinking water

Moorabool Water Treatment Plant which supplies ~90,000 people (35% of Geelongs’s population) in the Geelong (Victoria) area with drinking water. PFOS detections in raw water have averaged 4.3ng/L over the past 6 years.  This equates to just over 6% of the Australian Guideline level, but is higher than the US Guideline. This would warrant further investigations into the source of the PFAS and reticulated tap sampling, however under Australian guideline levels, this is unnecessary. Where has the PFOS come from?
