From vtdigger.org:
Low levels of the radioactive isotope tritium have been found in two monitoring wells on the Vermont Yankee compound over the last two weeks.
Though the source of the contaminated water has not yet been identified, officials say it could be coming from a new leak, possibly from pipes buried in soil near the radioactive waste treatment building, where radioactive fluids are treated and stored. As part of the new probe, an Entergy hydrogeologist will be sharing data with experts from New Hampshire, Vermont, Massachusetts and the Nuclear Regulatory Commission on Feb. 10.
The two monitoring wells that have tested positive for very low concentrations of tritium (between 1,000 and 9,000 picocuries per liter, well below the EPA standard of 20,000 pc/L) are located 200 feet and 100 feet, respectively, from tritium contamination that was discovered at the nuclear power plant a little more than a year ago.
