(IDAHO FALLS) – The U.S. Geological Survey says the Snake River Plain has experienced a big increase in nitrate levels. Local News 8 reports that the positively-charged ions are found predominantly in fertilizer, and can seep into groundwater during periods of increased run-off. They say nitrate levels quadrupled between 1993 and 2005, and are still on the rise. Officials encourage individual testing of wells to determine whether your drinking water is at a high-risk level.
