Australia is suing US conglomerate 3M for more than 2 billion Australian dollars (USD 1.4 billion) over so-called “forever chemical” contamination from firefighting foam at defense bases, the government said on Thursday.

A total of 28 sites across Australia are in the middle of the government's largest legal claim ever.

The Australian government says the US manufacturer withheld information about its toxic products that have caused health and land damage.
