A watershed-scale approach to tracing metal contamination in the environment
Stanley E Church
1996, Conference Paper
IntroductionPublic policy during the 1800's encouraged mining in the western United States. Mining on Federal lands played an important role in the growing economy creating national wealth from our abundant and diverse mineral resource base. The common industrial practice from the early days of mining through about 1970 in the...
