In addition to the hazards of tritium, harmful Cobalt-60 and Zinc-65 radioisotopes have been detected in groundwater at Vermont Yankee nuclear power plant. According to the Rutland Herald,  Co-60 levels are 130 times higher than federal reportable levels, while the Zn-65 levels are over 8 times higher than federal reportable levels. Tritium concentrations in a test well just 30 feet from the Connecticut River are higher than EPA Safe Drinking Water Act limits allow, and tritium concentrations in a radioactive waste trench are even in violation of NRC's lax groundwater standards. Meanwhile, Entergy Nuclear Vermont Yankee has hired a Washington, D.C. law firm to investigate allegations, and do damage control, concerning top ENVY officials providing false testimony under oath to state officials regarding the presence of buried pipes at Vermont Yankee that carry radioactive liquids.
