This report (Contract No. H0122070) describes the results of a two- phase investigation to identify sources and causes of mine water pollution in northern Idaho. The first phase effort examined the occurrence and production of acid water at the Bunker Hill Mine, utilizing a water-monitoring network that extended throughout the mine. The report shows that low ph water was formed in those mine areas containing lead-zinc ore rich in pyrite and that water movement in the mine was important both in the production of acid and also in transportation of heavy metals. The second phase evaluated water movement characteristics in an abandoned tailings pile and the resultant impact on the hydrologic environment. Initial data indicated (1) the existence of a ground-water mound under the pond and (2) the transfer of ions from the tailings pile to the surrounding ground-water system. The report is of special interest to the mining industry of the Coeur d'Alene District of Idaho and of general interest to persons concerned about pollution associated with mining.
