Brunswick previously reported detection of … Brunswick previously reported detection of tritium in excess of Nuclear Energy Institute (NEI) reporting criteria on June 13, 2007, i.e., EN 43420, as a result of water samples taken from an onsite shallow groundwater well (i.e., ESS 1BC) near the Storm Drain Stabilization Pond (SDSP). As previously indicated in EN 43420, the storm drain system routes tritiated water into the SDSP. Overflow from the Turbine Building air-wash system was identified as the primary contributor to the effluent of the storm drain system.
