Preliminary geology of the northwestern portion of Canyon County, Idaho. Technical report 200510 Item Info

The U.S. Environmental Protection Agency (EPA) promulgated a rule on 1217/2000 that requires a maximum contamirtant level (MCL) compliance at a concentration of zero pCiIL for radionuclides in community water systems. The Idaho Department of Environmental Quality (IDEQ) adopted this rule effective on 3/15/2002. Clearly, the source and distribution of water-born radiation must be well understood in order to effectively implement these new regulations. A number of ground-water quality problems exist within Canyon County, including locally elevated levels of radionuclides, naturally occurring concentrations of arsenic, agriculturally caused nitrate loading, and thermal water. Sampling by IDEQ has revealed strongly elevated levels of radiological constituents in ground water near Caldwell. The geographic extent of this problem is not fully known, and the source of the radionuclides not understood. IDEQ requested that the Idaho Water Resources Research Institute (IWRRJ) develop the first phase of a multi-year study that will result in an understanding of the geological sources and distribution of radionuclides that affect ground water as well's a hydrogeological characterization of aquifers in the study area. This report summarizes results from the geological portion of this initial study. This study was undertaken to aid in understand the source and distribution of elevated radionuclides in ground water in northeastern Canyon County. Our objective is to provide DEQ with information regarding radionuclide distribution, concentration in ground water.
