The Department of Defence has released the results of its investigation into PFAS contamination near the Blamey Barracks at Kapooka that found elevated risks to people and animals in the area.
Defence on Wednesday published its PFAS Management Area Plan and its Human Health and Ecological Risk Assessment report after more than a six month delay.
Per and poly-fluoroalkyl substances (PFAS) are found in certain firefighting foam that was widely used across Australia - including at both of Wagga's Defence bases - until the 1990s, which has been tentatively linked to human disease.
The new reports from Defence identified several PFAS contamination sites on the army base and that potentially contaminated surface water run-off into Kapooka Creek was of particular concern.
Kapooka Creek runs through the neighbouring rural suburb of San Isidore, which is 7 kilometres from Wagga's central business district.
Two San Isidore residents in May shared their concerns about PFAS in The Daily Advertiser, where they spoke of how the toxic chemical was affecting their lives and had left them feeling "trapped" on their contaminated properties.
Distressed homeowner Cheryl Balkwill has been unable to sell her property because it is contaminated.
"I only hope these reports will compel the Department of Defence to take responsibility and pay compensation in an expeditious manner," she said.
"This saga has made it impossible to move on with my life and has proven to be an exceptionally trying time both in my physical and mental health."
Defence's Human Health and Ecological Risk Assessment found that PFAS exposure risks within the Kapooka study area are generally low and acceptable.
However, for a small group of people who live within the study area and use water from Kapooka Creek dams to raise home-grown produce, a potentially elevated exposure risk has been identified.
People who eat fish from Kapooka Creek dams, or children who eat home-reared lamb watered from Kapooka Creek dams are potentially at risk, according to the report.
The PFAS Management Area Plan recommends actions including further testing, ongoing monitoring, and improving surface water drainage at the base to reduce the amount of PFAS entering Kapooka Creek.
Member for Wagga Joe McGirr welcomed the management plan, but said he would further review the reports and that he was arranging a briefing from Defence for more information.
"I remain particularly concerned about the impact on people whose properties adjoin Kapooka Creek," he said.
"As I have said previously, I believe the department should consider compensation for the affected property owners."
The Daily Advertiser sent questions to Defence but did not receive a response by deadline.
