Since the contaminated water tank experienced 300m3 leakage, high level of radioactive water Tritium has been measured in groundwater taken near the groundwater bypass wells. Tepco plans to discharge the pumped up water from those wells without filtration. (cf, [Tritium spread] 310,000 Bq/m3 of Tritium detected in the forest of downstream from 300m3 leakage tank [URL]) Regardless of the radiation measurements beside the wells, Tepco’s vice president Aizawa stated they still don’t think radioactive material reached groundwater bypass wells on 9/25/2013. He commented when they detect high level of radioactive material from groundwater bypass well, they would have to take countermeasures. However none of the details about the countermeasures were announced.
