Assessment of Ground and Surface Water Effects Around Coal and Mineral Storage Areas

摘要

The project investigated the impacts of coal and mineral storage piles on both ground and surface water quality. Ten coal and mineral stockpile sites (5 coal and 5 mineral--phosphate, lead, copper, iron, and uranium) across the country were visited to determine the actual impact of coal and mineral stockpiles on water quality. A series of leaching experiments was conducted in which drainage from the 10 coals and minerals was controlled and monitored to survey the extent to which storage piles release toxic ions to ground and surface waters. Pollution abatement techniques were reviewed in three generic treatment examples applied to lead-zinc ore, eastern coal, and uranium ore stockpile leachate.
