Hydrogeochemical investigations of historic mining districts, central western slope of Colorado, including influence on surface-water quality
Geochemical analysis of mine dumps, mill tailings, mine drainage, and surface waters indicate contamination from these historic mines is generally less than that asserted or suggested by some geochemical models |

Hydrogeochemical investigation of the Standard Mine vicinity, upper Elk Creek basin, Colorado
Ground- and surface-water samples were collected in order to characterize the local ground-water flow system, determine metal concentrations in local ground water, and understand factors controlling the discharge of metal-rich waters from the mine. |

Geochemical results from stream-water and stream-sediment samples collected in Colorado and New Mexico
Data from a study intended to explore how well the chemical analysis of water and sediment in an area reflects that of the rock from which the sediments are eroded and through which the water flows. |

Spring runoff water-chemistry data from the Standard Mine and Elk Creek, Gunnison County, Colorado, 2010
Periodic sampling of water during the spring of 2010 was carried out to understand the range and timing of variation in pH and metal concentration, and help evaluate variation in water quality during spring runoff. |
