Hydrologic and geochemical data and models supporting integrated evaluation of the Captain Jack Superfund Site, Boulder County, Colorado

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-01-21T00:00:00Z
This child item of the data release contains geochemical and environmental-tracer model inputs, outputs, model results, and a full model archive (model code). Dataset includes environmental-tracer concentrations, modeled recharge conditions (water temperature, excess air), resulting estimated groundwater residence times, and geochemical modeling simulations of aqueous speciation and water-rock interaction. This dataset supports an integrated hydrogeochemical investigation of solute sources, groundwater recharge processes, and groundwater flow in the vicinity of the Captain Jack Superfund Site, Boulder County, Colorado. Data were collected by the U.S. Geological Survey in cooperation with the U.S. Environmental Protection Agency.
