California on Wednesday became the first state in the nation to require water suppliers who monitor a broad class of toxic “forever chemicals” to notify customers if they’re present in drinking water. That could include sites from Los Angeles International Airport to military bases across the desert to refineries and other industry in low income neighborhoods.

Gov. Gavin Newsom signed AB 756, authored by Assemblywoman Cristina Garcia, D-Bell Gardens, late Wednesday with no fanfare.
