List of buried piping released

From the Brattleboro Reformer:

Two weeks ago, Yankee revealed a test well on site showed elevated levels of tritium in groundwater. The monitoring well showed levels of tritium ranging between 14,000 and 28,100 picocuries.

The source of the tritium has not yet been determined, but it was during the initial investigation that regulators learned there was in fact buried piping in use at the power plant.

Last week, during a search for the source, Yankee engineers discovered more than 200 gallons of contaminated water in a 40-foot-long pipe trench in the plant’s radiation waste building.

The water was found to be contaminated with up to 2 million picocuries per liter of tritium, 13,000 picocuries per liter of cobalt-60 and 2,460 picocuries per liter of zinc-65.

The Environmental Protections Agency’s drinking water limit for cobalt-60 is 100 picocuries per liter and for zinc-65 is 300 picocuries per liter.
