Section 4 <br />Potential for Rock to be Toxic-Forming <br />Leaching Potential: The potential for the development rock to generate toxic leachate was <br />evaluated using MWMP testing and evaluation of the volume of percolation that would be <br />expected from the piles. The MWMP testing indicates that the rock could release dissolved <br />constituents into pore water within the pile. However, detailed analyses of percolation from <br />the piles using water balance estimates and unsaturated flow modeling indicates that <br />generation of significant quantities of leachate from the piles is unlikely. These analyses <br />show that water infiltrating into the piles would be expected 1':o be removed by evaporation <br />in the and environment present at the Sunday Mines Group. <br /> <br />• <br />Cm 5-2 <br />T164985-0enison Mines\Task Order 3 • DMO Sampling and Analysis Plan\Task 3.12 Soil, Ore, Rock Data Assessment RepomSunday Rock R3porafinal repon\ReportWinal Sunday Minns Group Soil Ore Rock <br />Data Assessment Report_051509.dx
