I refer to the potential contamination of soil and water by chemicals known as per and poly fluoro alkyl substances (PFAS) found in fire retardant foam, and I ask: (a) have these substances been discovered in soil or water in Western Australia in any additional locations since the response given to my question on notice No. 465 asked on 31 October 2017; and (b) if yes to (a), where has it been found and in what concentrations?

(a) Yes. Since my response to Question on Notice No. 465 was tabled on 7 December 2017, per- and polyfluoroalkyl substances (PFAS) have been found in soil, surface water and/or groundwater at a number of additional sites within State jurisdiction being regulated under the Contaminated Sites Act 2003 (CS Act).
(b) The attached table [see tabled paper no.#] lists these additional locations and provides the minimum and maximum detected concentrations for the three most commonly tested PFAS [perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonate (PFHxS)]. Many of the additional sites are current or former Department of Fire and Emergency Services (DFES) facilities and current or former waste disposal facilities.
Similar to my previous response, a brief summary of the management actions required in accordance with the CS Act is included. At several of these sites, other types of contaminants are also present; the classification and management actions consider all types of contaminants at the site.
