Information on PFBS

“PFBS is associated with aqueous film-forming foam (foams (AFFFs) and used during chrome electroplating as a mist suppressant. It has also been found in food contact materials, dust, and source and finished drinking water. Accordingly, oral intake of water and food, inhalation, and dermal contact are plausible modes of PFBS exposure, with the oral route
being the primary route of exposure. PFBS has been detected in humans, confirming exposure to this PFAS; however, the magnitude of human exposure likely depends on factors such as occupation (e.g., processing and/or manufacture of PFBS or PFBS-containing products and
chrome electroplating) and living conditions (e.g., proximity to locations that make or use PFBS-containing products and nearby well-water use)…”

Area covered under EPA licence for Yackandandah WWTP. WWTP, holding dam and paddock south of the site are included in the licence.
