Australia's federal government is suing 3M for $2bn, alleging the company knew for more than 50 years that its firefighting foam containing Pfas chemicals posed health risks. This was reported by Qazaqyia.kz citing The Guardian.
In court filings as part of its $2bn lawsuit against the multinational company, commonwealth lawyers said products sold to Australia were known to persist in water and soil, accumulate in the human body and animals, and contribute to conditions including reduced kidney function, alterations in immune function, effects on fertility and puberty, and lower birth weight in babies.
In May, Attorney General Michelle Rowland announced the federal government was suing 3M and its Australian subsidiary over Pfas chemical contamination at 28 defence bases, seeking damages of more than $2bn (US$1.4bn).
The government alleges the use of per- and polyfluoroalkyl substances (Pfas) in firefighting foam has caused major environmental and economic harm, resulting in the largest legal claim brought to date by the Australian government.
Three key Pfas chemicals were banned in Australia last year due to long-running concerns about environmental contamination and health risks.
The massive statement of claim lodged in the federal court revealed the government will argue 3M's aqueous film-forming foam (AFFF) was known to be potentially damaging to the environment and causative of adverse health effects in humans, and that the company's Australian operations should have known no later than 1973.
Exhaustive research by government lawyers – detailed in more than 1,600 pages of filings – claims internal company documents included warnings about the products being toxic. One document from April 1981 showed 3M was not permitting women "of child bearing potential" to work at one of its plants in Alabama, "so they will not be exposed to a type of fluorochemical that can cause birth defects in rats".
Pfas are found in a wide variety of household and industrial products. The more than 14,000 compounds are difficult to break down and persist in the environment for long periods. Some, such as PFOA, one of the chemicals now banned in Australia, have been identified as cancer-causing in humans.
A group of 28 defence bases across Australia had been affected by use of the chemicals, the government said in May, requiring contaminated soil to be removed and treated.
Defence began phasing out Pfas chemicals in 2004.
The court filings revealed defence and other federal government employees attended demonstrations of AFFF products as early as 1967 and 1968, the same time as company brochures provided to the government said the products were "non-toxic" and had been widely tested.
According to the documents, purchasing of the products began in 1972, while sometime before December 1973, the company made statements to the effect that the products were "non-toxic" and "non-irritating" to humans, would not harm grass, were biodegradable and were "not expected to adversely affect the ecology of receiving streams in the vicinity of its use".
3M Australia offered large quantities of its AFFF product to Australia at a reduced price in September 1972, the documents showed.
A decade later, in June 1983, the federal government specifically requested 3M Australia identify whether AFFF "had any harmful environmental effects" and if "disposal of 3M AFFF after testing systems presented any problems."
From 1989 until about 2003, the commonwealth bought 3M AFFF on the condition that it conformed with defence standards, according to the filing.
Purchases of 3M AFFF ended in 2003. Since about 2011, the government has completed investigations and monitoring of potential Pfas contamination at bases and surrounding areas.
The filings claimed the chemicals were leaching into groundwater near bases, from concrete, asphalt, soil or sediment into surface water and drains. Widespread monitoring and investigations are ongoing, and more are expected in the years to come.
Lists of "high priority" bases with risk factors associated with AFFF are included in the filings. One list from 2016 suggested 24 priority bases requiring further assessment and investigation or action regarding potential Pfas impact.
The statement of claim details hundreds of millions of dollars in legal settlements for loss and damage, including $360m in class actions and more than $214m for ongoing investigations, monitoring, remediation and mitigation. More than $51m has been spent on research and evidence collection so far.
3M did not respond to a request for comment on Monday. In May, a spokesperson for the company said it never manufactured Pfas in Australia and stopped selling the products in question around two decades ago. The spokesperson said defence continued to use the products for nearly two decades. "We will defend ourselves against these claims through the legal process," the spokesperson said.
Earlier this month, federal court justice Catherine Button told a case management hearing in Melbourne that she had "never seen a" case like this.
