ALBANY, N.Y. (AP) — Claims over industrial chemicals that leached in the groundwater and soil along the St. Lawrence River since the 1950s, polluting tribal land downstream and harming wildlife, were settled Wednesday under a nearly $20 million agreement that includes money for environmental restoration and health and cultural programs for the affected tribe.

The settlement between Alcoa Inc., the St. Regis Mohawk tribe and state and federal officials involves discharges from two factories in Massena that released byproducts including potential carcinogens, damaging the environment and the downstream Akwesasne reservation along the Canadian border.
