PFAS permeation not an issue for HDPE Pipe
A recent study by water quality specialists from City West Water, Yarra Valley Water and South East Water published in Current Magazine in April 2020 investigated whether contaminants such as PFAS can penetrate through HDPE pipe, and hence affect the quality of drinking water in the reticulation system.
“The laboratory-based trial involved immersing sections of the HDPE (pipe) in a commercially available PFAS solution and testing for permeation.”
The HDPE pipe was tested after one, three and six months of exposure. The authors reported that no permeation of PFAS was observed.
Based on the findings of this study, there is no sign of any water contamination issue in regards to PFAS penetrating an undamaged HDPE Pipe.
