Dive Summary:

• More than 100 gallons of water containing radioactive tritium spilled from a discharge pipe at Duke Energy’s Catawba Nuclear Station near Lake Wylie, South Carolina-- the Nuclear Regulatory Commission reported Wednesday. The leak has the potential to affect ground water.
• The leak occurred in a fiberglass discharge pipe from the turbine building sump pump – a half-mile inside the station's grounds, Duke Energy Corp officials said.
• "If you do the calculations on that amount of tritium, it's less than half of the Environmental Protection Agency's drinking water standard," said Roger Hannah, a spokesman for the Nuclear Regulatory Commission's regional office in Atlanta.

From the article:
“Water has stopped flowing through the pipe and the spilled water contained no radioactive isotopes other than tritium, Andresen said. He said it would be some time before officials know exactly how much water was spilled because they must determine the flow, test pump logs and test soil around the underground pipe.”
