Environmentalists question safety of state’s weed-killing program

It is easy to see that the state Department of Transportation has finished up its annual half-million-dollar weed-spraying program for the summer.

You can tell by 3-foot-wide swaths of dried, brown vegetation along 5,000 miles of guardrails, sound barriers and center medians on Connecticut highways and secondary roads.

“The weeds, grass and vegetation grows back the next season,” said Adam Boone, who heads the DOT’s herbicide program. “It minimizes the manual labor needed to control growth.”

The DOT stresses that its crews are well-trained and the chemicals are safe, and the state Department of Energy and Environmental Protection approves the method.

The environmental community, however, is not so sure about the safety.
