Hydrogeochemistry of the gold deposits of the Baley district

Questa baseline and pre-mining ground-water quality investigation. 25. Summary of results and baseline and pre-mining ground-water geochemistry, Red River Valley, Taos County, New Mexico, 2001-2005

“…Most mine sites have no direct or reliable information regarding ground-water quality, although many surface-water samples have been analyzed for acid and metal contaminants. Documented ground-water chemistry (not just the water chemistry of mine water discharged to the surface) affected by mining operations include midwestern lead-zinc mines of the United States (Playton and others, 1980;Parkhurst, 1987;Toran, 1987), coal mines in Illinois and Appalachia (Booth, 2002;Brady and others, 1998), mines in Europe, South America, Russia, and South Africa (Goleva, 1977;Vartanyan, 1988;Fernández-Rubio, 1999;Younger and Robins, 2002;Younger and others, 2002).…”
