Application of a coal-pile drainage model to an industrial/institutional site
This report describes the site selection, field sampling and analysis and mathematical model calibration and verification process used to apply a coal pile drainage model to an industrial/institutional site, e.g., a small storage pile of less than 25 tons. The field program included 10 weeks of monitoring drainage flow, pH, conductivity, precipitation, coal moisture, and pile infiltration rates with the analysis of drainage water for acidity, filterable and nonfilterable residue, sulfate and ten trace metals. The program was performed at Cornell University's steam plant coal pile. Five storms were sampled ranging from 0.62 inches to 1.59 inches of rain. The pH of the runoff was generally in the range of 2.0 to 2.8. In several instances, metals concentrations exceeded New York State Department of Environmental Conservation (NYSDEC) effluent limitations for Class GA waters. The model which has two parts, H20TRC (hydraulic) and TRCCOAL (water quality) was calibrated and verified using the field data. The hydraulic portion was able to predict flows within 12% for large storms. The water quality portion was able to predict within 20% for sulfate and iron loadings but was not as accurate in predicting the acid loading. 21 figures, 13 tables.
