Post-Florence coal ash tests at 1 site yet to raise alarms

RALEIGH, N.C. (AP) — North Carolina environmental officials say sludge washed from buried coal-ash pits by Hurricane Florence’s flood waters hasn’t polluted a neighboring river with heavy metals at levels concerning to human health.
State officials say water samples taken from three sites near Duke Energy Corp.’s closed H.F. Lee power plant in Goldsboro more than a week after Florence hit the state, found arsenic, mercury and three other metals within acceptable levels.
