Water pollution potential of snowfall on spent oil shale residues.
NTIS: PB 210 930 Available for Reference At Bureau Libraries 1972; :1-53
The concentration and composition of totally dissolved solids were determined both in surface runoff water and in water which had percolated through a bed of the residue. An empirical equation was developed to predict the concentration of the runoff water as a function of independent parameters. A tendency for saturation of the residue to occur during a period of snowmelt was revealed. The effects of this saturation on the residue were also considered. An overland-flow water quality model was developed and successfully applied to runoff resulting from rainfall and snowfall on oil shale retorting residue. The surface water runoff from snowfall on oil shale residue has less water pollution potential than the runoff from rainfall. The concentration of dissolved solids in the runoff was a function of the cummulative volume of runoff per unit width, the porosity of the oil shale retorting residue, the soil moisture content, the snowmelt rate, and the fraction of the snowmelt water that is runoff.
