PFAS investigations underway at Munmorah and Colongra Power Stations

Media release: 5 September 2017

The NSW Environment Protection Authority (EPA) has directed Generator Property Management and Snowy Hydro to undertake further testing at the Munmorah and Colongra Power Stations as part of the state-wide PFAS* investigation program. 

Preliminary sampling shows the presence of PFAS in the soil, surface water and groundwater at, and around, these sites.

EPA Regional Director North Adam Gilligan said it was not unusual for PFAS to be detected at large-scale industrial sites such as power stations. 

“Given PFAS-containing foams were used and stored in such large quantities at these sites, these initial results are to be expected.

“The important next step is to find out the extent, and if there are any ways the local community could be exposed to PFAS.

“As none of the groundwater bores, nor surface water on site are used for drinking or cooking purposes, and there is no produce grown on site for food, we think the risk to staff that work on site is currently low.

“Anecdotally we know that some community members may be fishing in the canals on, or around the power stations. I’d like to remind the community that fishing in these canals is not permitted. 

The additional testing to be undertaken by Generator Property Management and Snowy Hydro will include fish sampling around the power stations and in the wider Tuggerah Lakes System. It will also include undertaking a water use survey of nearby residents to gain an understanding of how the ground and surface water is used in the area. These findings will enable the NSW Government to appropriately assess and communicate any further precautions to the community.
