What is AFFF?
Aqueous Film Forming Foam. is used to assist with fire fighting activities.
AFFF products have been used in the community and Defence for decades.
• AFFF contains Perfluorinated Chemicals (PFC’s) - Perfluorooctane Sulphonate and
Perflurooctanoic Acid (PFOS/PFOA).
• The 3M Company was the primary manufacturer of PFOS – up until in 2002 when
production ceased.
What is PFOS/PFOA?
• PFOS and PFOA are man-made fluorinated chemicals.
• Lipid-repellent and water-repellent characteristics provide soil, oil and water resistance
to a wide range of products: carpets and textiles, paper and packaging, coatings,
industrial and household cleaning products.
• PFOS and PFOA are chemically and biologically stable. They are resistant to breakdown
by sunlight and water.
• Persistent in the environment.
What is the situation at AACO?
• Base is connected to the town water supply in 19??.
• Environmental investigations commenced in 2010 to define potential contamination.
• PFOS/PFOA were identified in 2011 in groundwater.
• Defence historically used the groundwater for irrigation purposes and filling of the pool.
Since ceased.
• PFOS pool samples = 8.5 µg/L
• Indicative Human Health Risk Assessment (IHHRA).

What does this mean for you?
• Health risk from pool = Low
There is no acute level of health risk from skin exposure.
• The health risk from oral exposure is based on general exposure assumptions from
enHealth 2012.
• Stockholm Convention May 2009, recognised as Persistent Organic Pollutant (POP)
What Happens Next?
• Continued environmental investigations.
• Environmental investigations outcomes - Inputs to HHRA
• Specialised water treatment plant to clean pool water.
• Defence will keep you informed.
• The risk is low.
• Bore water use not for drinking.
• Bore water for irrigation continue
