• EPA’s MCL for I-131 in drinking water is 3 pCi/L. This level was set to be protective over a 70 year period of continuous intake at that level. A slight increase over this level for a short period would not necessarily cause a public health concern. If a water system is found to have levels higher than the MCL for a sustained period of time, the water system administrators would likely explore options for how to lower the levels. This could include finding alternate sources or additional treatment.
