2. Environmental Monitoring Media near nuclear facilities are monitored by the ERE Branch, a non-regulatory program in the NC Radiation Protection Section. The goal is to provide an independent check and confirmation of utility results. Due to size and resource constraints split sample monitoring can occur at only at limited number of sites.

24. Notification On 6/15/07 RPS personnel were notified that tritium had been discovered in water in a manway near the elevated stabilization pond at the Brunswick plant. Brunswick personnel arranged for contractors to sink wells in the shallow, intermediate and deep aquifers at the site. RPS agreed to perform split sampling of ground water with Brunswick personnel.

34. Ongoing Activities Regular sample collection from wells around the stabilization pond continues. RPS staff will conduct split sampling of ground water at sites 24A,19B, and 19C during April,2008. Contacts between RPS and utilities are continuing regarding ground water tritium monitoring projects.

41. Conclusions Performing split sampling as a follow on to existing activities has been possible due to close coordination w/ utility. Agreement of limited set of split samples was generally good based on simple ratios. State involvement assisted local environmental agencies in their information gathering. A limited number of sites may be recommended for inclusion in the State’s routine monitoring program.
