| event text = On Monday, August 13, 2012, analyses of samples taken from groundwater inleakage to the Nine Mile Point Unit 1 (NMP1) Screenhouse building confirmed the presence of tritium at concentrations of approximately 32,000 to 44,000 picocuries per liter (pCi/l). This discovery was made during the conduct of the site's ongoing groundwater monitoring program. These concentrations are above the 30,000 pCi/l threshold for voluntary reporting for a non-drinking water pathway, as indicated in Nuclear Energy Institute (NEI) 07-07, Industry Ground Water Initiative - Final Guidance Document. | | event text = On Monday, August 13, 2012, analyses of samples taken from groundwater inleakage to the Nine Mile Point Unit 1 (NMP1) Screenhouse building confirmed the presence of tritium at concentrations of approximately 32,000 to 44,000 picocuries per liter (pCi/l).

These test results do not indicate any threat to public health or safety, since the building inleakage is not a drinking water source, and there is no indication that tritium has migrated off the Nine Mile Point site in the groundwater. Nine Mile Point Nuclear Station, LLC, is continuing an investigation to identify the source of tritium and implement a corrective action plan. | These test results do not indicate any threat to public health or safety, since the building inleakage is not a drinking water source, and there is no indication that tritium has migrated off the Nine Mile Point site in the groundwater.
