The levels of the radioactive isotope tritium in a monitoring well at the Pilgrim nuclear power plant have dropped significantly since they were found to have exceeded federal drinking water standards on July 7.
The Nuclear Regulatory Commission said a level of 6,870 picocuries per liter of tritium was found in a monitoring well on July 15, compared with 25,552 picocuries per liter on July 7.
The federal maximum standard for drinking water is 20,000 picocuries per liter. Although the well is more than two miles from the nearest drinking water source, Entergy Corp. officials have stepped up their efforts to trace the source of the elevated tritium. Entergy, the plant’s owner, has noticed elevated levels of tritium since it first installed the well in the spring.
