Examination of dissolved uranium concentrations in regional shallow groundwater relative to Operable Unit 8 of the Denver Radium Superfund Site

A radium industry existed between about 1914 and 1920 in Denver, Colorado, with operations located along the South Platte River. Sites associated with that industry were contaminated with radium and uranium processing residues and were incorporated into clean-up efforts as Operating Units (OUs) of the Denver Radium Superfund Site. Concentrations of uranium exceeding the U.S. Environmental Protecti

Over a third of groundwater in USA public-supply aquifers is Anthropocene-age and susceptible to surface contamination

The distribution of groundwater age is useful for evaluating the susceptibility and sustainability of groundwater resources. Here, we compute the aquifer-scale cumulative distribution function to characterize the age distribution for 21 Principal Aquifers that account for ~80% of public-supply pumping in the United States. The aquifer-scale cumulative distribution function for each Principal Aquif

Characterization of and temporal changes in groundwater quality of the Upper Black Squirrel Creek Basin, El Paso County, Colorado, 2018–20

In 2018–20, the U.S. Geological Survey, in cooperation with Upper Black Squirrel Creek Ground Water Management District, sampled 48 wells for Phase III of a multiphase plan investigating groundwater quality in the alluvial aquifer of the Upper Black Squirrel Creek Basin (UBSB), El Paso County, Colorado. Results for samples collected from October to December each year were used to assess spatial an

Data supporting management of thermal springs –Steamboat Springs, Colorado

The U.S. Geological Survey (USGS), in cooperation with the city of Steamboat Springs and the Tread of Pioneers Museum, is undertaking a geologic, hydrologic, and geochemical study to better understand the sources of water to hot springs and the possible effects of land use change and human activities on the chemistry and sustainability of springs.

Actionable Science

The Colorado River Basin Pilot Project is exploring new approaches for the USGS to answer complex earth systems questions identified in partnership with stakeholders, which cannot be answered through a single discipline approach. Science coproduction is a method where scientists, managers, policy makers, and other stakeholders first identify specific decisions to be informed by science, and then...

Integrated Science Approach

The USGS has a long history of delivering science and tools to help decision-makers manage and mitigate effects of drought. The timing is critical for the USGS to consolidate its diverse expertise into a single landscape-scale effort to rapidly provide integrated transdisciplinary, targeted data, tools, and models required by decision makers in the Basin. This initiative unifies USGS expertise...
