The licensee preliminarily Identified one residential location directly north of Faltan Pond to have detectable tritium (1,150 pci/I). Furthermore, the licensee drove new wells (depth of 12 feet) north of the Faltan Pond and preliminarily reported tritium concentrations between (4,200 - 6,200 pcI/L). Nearby residential wells (SOUTHWEST of Faltan Pond) have not shown any tritium above normal background. However, the licensee detected elevated levels of tritium (as high as approximately 33,700 picoturies per liter) in monitoring wells in a vacant development immediately offsite. The licensee continues to monitor and to develop plans for remediation, with Region III inspection oversight. Region III has also sent split samples from some offsite wells to the NRC's contract laboratory for independent analysis.
