Title	Offsite Notification Due to Tritium in Onsite Water Samples
Event Description	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. The air-wash is no longer routed into the storm drains, which eliminated the main source of the tritium into the storm drain system. On March 6, 2008, an ongoing investigation determined that tritium levels in excess of NEI voluntary reporting criteria present in an onsite shallow groundwater well (i.e., ESS-2C), resulted from a condition not previously reported. Though elevated levels of tritium for each incident are most likely a result of the same source (i.e., effluent routed in the storm drain system,) subsequent investigations indicate that the storm drain piping may allow an inadvertent pathway to groundwater in close proximity to ESS-2C. The monitoring well ESS-2C is well within the boundaries of the site owner controlled area and there is no indication that tritium has migrated into any drinking water. The following agencies will be updated on the status of the onsite tritium samples and informed of the pending press release: State Officials, City of Southport, Brunswick County, NEI, INPO, and ANI. The Licensee notified the NRC Senior Resident Inspector.
