Please see the attached sample data work book. The IP-2 FSB leak area water volume collected and activity concentrations are essentially consistent with data from previous samples. No note worthy changes in activity or volume collected are evident.

A new work sheet "Monitor_Well" has been added to track sample data from site monitoring wells. C)f note, is the tritium activity level 2.1 2E-4 uCVmLi reported in MW-i 11 in the IP-2 Transformer yard.

Confirmiatory samples will be taken tomorrow. A portion of the initial sample is being analyze by the site Chemistry group. JAF is analyzing another aliquot from the initial sample volume. Additional sample points lave been identified and samples will be acquired from those points. A CR has been generated and the NRC has been notified.
