Description:
This report describes a study of water pollution levels that result from coal stockpiles maintained outdoors. A representative source was defined to characterize the pollution levels. Effluent data was obtained by placing coals, collected from various regions in the U.S., under a rainfall simulator. Drainage samples were analyzed for water quality parameters, organic and inorganic substances, and pollutants covered by effluent limitations. Coal drainage effluent concentrations, rates, and factors were determined. Hydrologic relationships were used to calculate the diluted concentrations entering a waterway. The ratio of this level to water quality criteria was determined as an indication of the potential environmental impact.
