"EDEN, N.C. – An environmental group Thursday challenged Duke Energy’s assurances that drinking water from the Dan River in North Carolina and Virginia remained safe despite a massive spill of toxic coal ash that released a deluge of murky gray sludge into the river Sunday."

"A record-number of people lost their power across the region thanks to a significant ice storm and power officials warn it could be days before everyone has their electricity back."

"ON THE DAN RIVER, N.C. — Canoe guide Brian Williams dipped his paddle downstream from where thousands of tons of coal ash has been spewing for days into the Dan River, turning the wooden blade flat to bring up a lump of gray sludge."

"SAN JOSE, Calif.—The attack began just before 1 a.m. on April 16 last year, when someone slipped into an underground vault not far from a busy freeway and cut telephone cables."
