Groundwater pumping is causing rivers and small streams throughout the country to decline, according to a new study from researchers at the Colorado School of Mines and the University of Arizona.

Officials say contaminants are present in groundwater near an electric company's northern Colorado facility, and reports suggest the coal-fired facility may be the cause.

The Daily Reporter-Herald reports staff at the Platte River Power Authority's Rawhide Energy Station in Wellington said Thursday that it is working to find out more information about the toxins' presence.
