"The full report presents a description of the magnitude and distribution of copper dump leaching, the design and operation of leaching facilities, the potential for environmental impact, and management practices that can be used, to minimize environmental releases. The information contained in the report was obtained through searches of published and unpublished literature and through contact with knowledgeable individuals involved in the dump leaching industry. Ten leaching operations were visited to acquire firsthand knowledge and site-specific information. Seepage frqm leach dumps and process solution collection systems is the most significant potential mechanism for the release of contaminants. These solutions have low pH and high concentrations of metals and total dissolved solids (TDS). Ground-water impacts have been documented. The application and efficiency of standard waste management practices at dump leach operations are site specific and are limited by the magnitude of these facilities."
