Cynthia Nixon tore into Gov. Cuomo on Wednesday over the state’s handling of contaminated drinking water in upstate Hoosick Falls.

“You can bet if this was a town that was in Westchester near New York City — a town with a lot of wealthy people donating to politicians’ campaigns — this would have been addressed a lot sooner,” the actress said at a meeting with residents of the town.

Nixon said the administration should have been “trumpeting it from the tallest hills” that residents “don’t drink the water — it’s poison,” when it learned that cancer-causing perfluorooctanoic acid had reached dangerous levels.

Cuomo spokesman Rich Azzopardi responded:

“Our commitment to the Hoosick Falls community has been unwavering and will remain so until the job is done.”

Earlier Wednesday, Nixon told TV host Wendy Williams that she supports legalizing pot.

“I’m absolutely for the legalization of marijuana. Let’s capture some of that revenue,” Nixon said.

Asked about the marijuana remark in Hoosick, Nixon blamed state Republicans for holding up legalization and argued that people of color are disproportionately punished for “something white people do with impunity.”

About the governor’s claim that she is using her fame as an actress, Nixon said that when Cuomo first ran, he was a celebrity for being the son of former Gov. Mario Cuomo.
