Those elevated H-3 concentrations are outliers relative to tritium concentration results reported for other intermediate wells. The licensee stated that semi-permeable geological layers are less robust in this specific area beneath the pond and are believed to be a contributing factor to the observed elevated H-3 concentration results.
FYI as a follow-up, this is a schematic provided by the licensee regarding the underlying geological substrates and the location of the various aquifers in this area. We will continue to focus on the results for this intermediate well (19b) results as a potential problem which could lead to contamination of the intermediate aquifer.
