Story summary

The University of Chicago Pritzker School of Molecular Engineering and Argonne National Laboratory developed a portable PFAS detector for water.
The device identifies PFAS at 250 parts per quadrillion, far faster than weeks-long traditional methods.
The U.S. Environmental Protection Agency has proposed new limits for two toxic PFAS, PFOA and PFOS.
The technology aims to address the challenge of PFAS detection and elimination.
