Description:
This effort involved the organization and statistical analysis of a large amount of data characterizing over 300 surface and underground coal mines and quantification of the pre- and post-treatment quality of their wastewaters. Only existing data, supplied to Hittman Associates by EPA, was utilized in this evaluation. The study objective was to determine whether the data supported the development of a separate Effluent Guidelines subcategory for coal-mining point source discharges to differentiate between eastern and western coal mining activities. An extensive effort was required to convert the data into a computerized format which would allow for expeditious statistical analysis.
