Radiation detected in groundwater at Exelon's Peach Bottom nuclear plant | 19 June 2015 | Radiation at levels above industry safety thresholds was detected in groundwater at Peach Bottom Atomic Power Station [Delta, PA], according to an Exelon report to the Nuclear Regulatory Commission. Exelon, the company that owns and operates the power plant, reported that on April 17, a groundwater monitoring well detected tritium -- a radioactive isotope -- at 37,700 picocuries per liter. Neil Sheehan, Nuclear Regulatory Commission spokesman, said Exelon has to report any level of tritium in excess of 20,000 picocuries per liter, the EPA-endorsed threshold for safe [sic] levels in drinking water.
