Idaho's Department of Environmental Quality reported today that samples of drinking water collected from across the state are no longer showing detectable amounts of radiation.
On March 22, the U.S. Environmental Protection Agency detected rainwater in Boise with radiation levels at 242 picocuries per liter. The levels of iodine-131 in the water samples were blamed on the radiation from the Fukushima Daiichi nuclear disaster.
In the wake of the discovery, the DEQ had been testing water samples from Boise, Fruitland, Horseshoe Bend, McCall, Weiser and 13 other towns throughout the state. Since its recent samples registered "nondetectable" iodine amounts, the DEQ will return to its regularly scheduled routine sampling.
