This child item of the data release contains groundwater-level elevation and water-quality data, both collected by contractors to U.S. Environmental Protection Agency (EPA) and later furnished to U.S. Geological Survey (USGS), and water-quality data collected by USGS during 2020. The USGS sampling and analysis resulted in a diverse dataset including major and trace elements, rare earth elements (REE), stable isotopes, radiogenic isotopes, and environmental tracers. This diverse dataset aids in providing a complete hydrologic and geochemical conceptualization of the processes occurring in the mine workings and adjacent groundwater and serves as an example of applications to other sites.

U.S. Geological Survey (USGS) in cooperation with the U.S. Air Force Civil Engineering Center conducted short-term aquifer tests at 11 wells to estimate hydraulic properties in the Fountain Creek alluvial aquifer, in El Paso County, Colorado. Data were collected in July 2019 over three days. Single-hole pumping and recovery tests were completed at five wells, and multiple single-hole displacement (solid slug) tests were conducted at all 11 wells. This data release contains water-level data collected at various time intervals (0.25 seconds, 0.5 seconds, and variable during a manual test with a stopwatch) and well-discharge rates for the aquifer tests in comma separated value (CSV) files for the 34 tests analyzed....

Short-term aquifer tests were conducted to estimate hydraulic properties in an alluvial aquifer. Tests included eight single-hole pumping and recovery tests and three slug tests (in a single well). These investigations were conducted in the Wet Mountain Valley, in Custer and Fremont Counties, Colorado. The U.S. Geological Survey (USGS) conducted aquifer tests in May, 2019. These aquifer tests inform the conceptual understanding of the valley-fill aquifer and serve as primary inputs to the numerical groundwater-flow model. Testing was completed in cooperation with the Upper Arkansas Water Conservancy District. This data release contains raw data from aquifer tests, water-level and pumping discharge rate measurements,...

The Captain Jack Superfund site near Ward, Colorado hosts extensive interconnected underground mine workings, which drain via the Big Five Adit. Drainage from the adit has historically been acidic with elevated concentrations of metals. In 2018 the U.S. Environmental Protection Agency (EPA) utilized a subsurface remediation strategy consisting of the installation of a hydraulic bulkhead within the workings to preclude drainage out of the mine. To understand the processes occurring during water impoundment within the mine workings, the U.S. Geological Survey (USGS), in cooperation with EPA, completed water-quality sampling and analysis during 2020 as water was impounded within the mine workings. The USGS sampling...

The U.S. Geological Survey (USGS) used an analytic-element method (AEM) modeling approach to quantitatively understand groundwater dynamics at the Captain Jack Superfund Site, located in Boulder County, Colorado. The Captain Jack Superfund Site hosts extensive interconnected underground mine workings.The U.S. Environmental Protection Agency has instituted a remedial strategy of impounding water within the mine workings behind a hydraulic bulkhead in May 2018. The AEM is a grid-less modeling framework where multiple hydrologic stressors may be superimposed upon one another, resulting in a prediction of the bulk system response. This screening-level model could be used for evaluation of boundary conditions, hydraulic...
