PFAS Testing on Council Facilities


Following on from the ongoing Department of Defence PFAS (Per- and Polyfluoroalkyl Substances) testing across a number of sites in the Katherine region by Coffey Consultants, testing is now occurring on Katherine Town Council facilities.


PFAS has been used for decades in hundreds of industrial applications and consumer products such as carpeting, apparels, upholstery, food paper wrappings, fire-fighting foams and metal plating.


A regime of testing is now underway on Council facilities that may have levels of PFAS that could impact on human health. This is part of the overall investigation of PFAS use at RAAF Tindal Base by Coffee, in the Katherine Township. Ongoing monitoring and public reporting of all facilities is planned.


Aquatic Centre water quality results


This table shows the concentration of PFAS in the water at the Katherine Aquatic Centre. Bore and pool sampling at the Aquatic Centre will be undertaken fortnightly to build baseline data and ensure that the water quality remains within the national health based guidance values (HBGV). The table will be updated with the results of ongoing testing as it becomes available.

As a result of the most recent test taken on 28 September 2017 Katherine Town Council has taken the proactive steps to temporarily close the swimming pool to immediately address the issue. Updates will be provided to the community via this website, the Katherine Town Council Facebook page and local media sources as they become available.

The national Health Based Guidance Value (HBGV) for PFOS/PFHxS for recreational use is
0.7 micrograms per Litre (µg/L). For PFOA the HBGV is 5.6µg/L for recreational use.
