Feds reach $5.15B settlement over mining cleanup

FLAGSTAFF, Ariz. (AP) — For decades, uranium ore was mined from the Lukachukai Mountains of northeastern Arizona, providing Navajos with much-needed employment but leaving behind a legacy of death and disease on the reservation.

Uranium waste was thrown over the mountainside and carried by rain across the remote but scenic land used by hikers, anglers, medicine men and Navajo shepherds. The roughly 50 mine sites were eventually abandoned without cleaning up the contaminated waste.
