The Vermont Yankee nuclear plant has finished testing a former drinking water well to make sure it hasn't been contaminated with radioactive tritium.

The well supplied the plant until it was closed in 2010. It was the closest drinking water supply to where tritium had been found.

The Brattleboro Reformer reports that plant officials said no tritium or gamma-emitting radioactive materials were detected in a sample taken last month.
