PFAS Sleuths Seek ‘Forever Chemical’ Fingerprints

Researchers at the Columbus, Ohio-based Battelle Memorial Institute are developing a process to find signatures common to various sources of PFAS contamination.

The process works by creating a library of the chemicals, which is then grouped into categories, such as contamination that would indicate a source from a textile plant versus a paper plant.

“When we’re looking at a particular signature, it is so common across all of these sources,” Kavitha Dasu, principal research scientist at Battelle said. “We understand all of these things and we have come up with some of the distinct signatures of each of these applications, which chemicals are used for any particular application.”
