Experimental monolayer evapotranspiration cover systems were installed in 1997-98 over mine tailings at the Morenci mine in the semi-arid southwestern United States. Test plots were constructed on the tailings dam sideslope to examine effects of cover treatments on vegetation and net infiltration flux into the tailings.
Reclamation field studies were designed at the Phelps Dodge Morenci Mine in Arizona to evaluate the benefits of biosolids, cattle impact, and other treatment variables on soil-capped tailings.
