The Vermont House has approved a bill providing for stricter regulation of toxic substances.

“The bottom line is that Vermonters deserve to know what toxic substances they are exposing themselves and their families to,” said Speaker of the House Mitzi Johnson in a statement on Thursday. “This bill takes a modest but important step to better protect Vermonters, especially our children, from toxic chemicals.”

The bill approved last week, S.103, is a version of a bill introduced last year following the discovery of PFOA contamination of drinking water in wells of Bennington residents.

The House version is a pared-down version of the original 81-page toxic substances regulation bill, which was introduced by Sens. Brian Campion, D-Bennington, and Ginny Lyons, D-Williston, along with eight others, last year. One of the sections, which was cut last year — making individuals and businesses liable for releasing toxic chemicals — was revived this year as S.197, which recently passed the Senate.
