National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Natural Attenuation Capacity of Santa Cruz Area Rocks to Partition Mobile Solutes from In situ Leachate.

PB92166586

Publication Date	1992
Personal Author	Marozas, D. C.; Paulson, S. E.; Callahan, T. J.
Page Count	60
Abstract	The U.S. Department of Interior, Bureau of Mines is conducting research on the capacity of natural fluid/rock interactions to attenuate major and trace elements at the Santa Cruz In Situ Copper Mining project site. This report presents results from a series of experiments designed to quantify the changes that natural reactions will cause in the composition of mining leachate with time. Several different rock types in the Santa Cruz area were tested and the effect of rock type on attenuation was evaluated. Calculated experimental attenuation coefficients are presented as a method of quantifying attenuation capacity. Geochemical reactions that can cause subsurface attenuation of various leachate constituents are also discussed.
