Two water utilities in Tennessee have tested positive for high levels of lead, but Tennessee environmental regulators say the findings are likely due to sampling errors.
Tennessee Department of Environment and Conservation spokeswoman Kelly Brockman said that two of the state's 504 utility districts have been deemed to be out of compliance with water quality rules. The two utilities in question include an East Tennessee agency serving a community of about 3,700 people northeast of Knoxville. The other is a factory with about 35 employees with its own water source in West Tennessee.
Brockman says four out of 20 initial samples exceeded the lead action level. When those 20 samples were taken again, plus an additional 20, she says that all of the samples came back below the action level.
