"RALEIGH, N.C. - North Carolina's environmental agency said Sunday it wrongly declared all test results for the arsenic levels in the Dan River as safe for people after a massive coal ash spill."
"A water sample taken Monday, two days after the spill was discovered, was four times higher than the maximum level for people to have prolonged contact, such as swimming, the state Department of Environment and Natural Resources said.
'We made an honest mistake while interpreting the results,' state Division of Water Resources director Tom Reeder said in a statement."
