KINGSTON, Tenn. — Federal data shows arsenic levels more than 100 times the acceptable amount in a river near a massive coal ash spill in East Tennessee.
The U.S. Environmental Protection Agency has said water samples from near the spill were above federal maximums for contaminants. Data released Friday showed total arsenic levels in one sample were 149 times the maximum level.
The data also showed that samples taken near the Kingston water treatment plant _ which is upstream from the spill site _ were found to be within the federal limits, except for thallium.
A retention pond burst at the Kingston Steam Plant last month, spreading more than a billion gallons of sludge. The plant is run by the Tennessee Valley Authority, the nation's largest government-owned utility.
