Testing is still at a small scale, but U.S. Navy researchers are encouraged by their work to develop new firefighting foams that do not contain the 'forever chemicals' known as PFAS.
Testing is still at a small scale, but U.S. Navy researchers are encouraged by their work to develop new firefighting foams that do not contain the"forever chemicals" known as PFAS, that at high levels have been linked to increased health risks, including cancer.
Over time, the PFAS in the foam enters the groundwater surrounding some military bases, which affects drinking water. "We have two goals. One is to eliminate PFAS, so we're working with completely fluorine-free materials" Dr. Ramagopal Ananth, a Navy Research Laboratory chemical engineer and principal investigator, told ABC News. The other goal is to"provide the same level of protection to the warfighter."
The silicon is not only bio-degradable but is also"cannot make any PFAS at all," according to Ananth. Promising results of the new foam in the test lab led to a larger test in late October at the Naval Research Laboratory in Washington D.C.
