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
Synoptic water-quality and benthic macroinvertebrate sampling at 14 stream sites to characterize the quality of surface water in the watershed on a seasonal and spatial basis, as well as to assess the effects of wetlands on water quality.
Geochemical analysis of stream waters and sediments in mountainous areas immediately west of Denver, Colorado, to evaluate the concentration and distribution of uranium-bearing acid drainage originating from historical mines
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.
Multi-element geochemical analysis of host rock, ore, mine waste, flotation-mill tailings, slag, stream sediments, creek and adit waters, and leachates of mine waste and mill tailings.
Geochemical analysis of water samples to provide a pre-reclamation assessment of seasonal variations of acid and metal concentrations in Knight's Branch help evaluate the reclamation project.
Sampling procedures, analytical methodologies, and results to assess the potential for mine waste and drainage to have an adverse impact on aquatic ecosystems, on drinking- water supplies, and to human health
Summary of data obtained from field sampling of mine tailings and waste rock and water and sediment in regional springs and tributaries that drain from the mine area into Bear Creek. Ground-water springs are also potential sources of mercury here.
