DANVILLE, Va. - Duke Energy will begin the long process Tuesday of removing the toxic sludge that spilled into the Dan River.
Thousands of tons of coal ash spilled into the river near the Virginia border after a pipe failed beneath a retention pond in February.
Crews will use a park in Danville, Virginia as their staging area and the entire process is expected to last through July.
Duke Energy said the water is safe to drink but environmentalists are concerned about the long-term impact.
