The University Playing Fields utilise recycled water from the Glenelg North Waste Water Treatment Plant. The recycled water has been tested for PFAS by Adelaide Airport Limited**, and was found to have detectable concentrations below the drinking water criterion of 0.07 μg/L.

The presence of detectable concentrations of PFAS in recycled water would be contributing to the contaminant load of PFAS within the aquifer, however the significance of this is likely to be minimal, but may warrant further investigation to confirm
