Tell Governor Hochul to stand up and protect our drinking water from PFAS
The federal government is trying to scrap nationwide limits on PFAS in drinking water, which will leave millions of New Yorkers exposed to these toxic chemicals when they turn on the tap. The Governor has the authority to maintain strong limits on PFAS in drinking water. Tell Governor Hochul that we need her leadership to ensure every New Yorker has clean, safe water.
Defend declining eels from deadly dam dangers
Hydroelectric dams pose a significant threat to Hudson River eels, blocking them from critical spawning habitat and sucking them into deadly turbines. Join us in calling for the modification of hydroelectric dams in order to protect this unique and iconic Hudson River species.
