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 |
