Northern Water has discovered uranium-bearing minerals in the early phases of water testing at Chimney Hollow Reservoir, a project west of Carter Lake in Larimer County. At Chimney Hollow, it is “naturally occurring in the granitic rock formations that were quarried to supply material for the dam,” according to a June 5 press release from Northern Water. Northern Water is conducting tests and modeling what the extent of the uranium leaching could look like as they begin filling it. Tests will continue over the next several years while Northern Water pursues mitigation strategies, which could include treatment or reduction through significant dilution, according to Stahla.
