Interchange of pollutants between groundwater and mineral strata as applied to waste chemical dumps and 'in situ' coal gasification sites. Completion report, 1 October 1979-30 September 1980
The overall objective of this research was to study the interchange of pollutants between minerals and groundwater produced as leachate from waste chemical dumps and as a by-product of in situ (underground) coal gasification. Particular emphasis was placed upon the development of methods to evaluate the chemical interaction between contaminated groundwaters and specific solids so that these methods could be applied to specific situations which other investigators might need to study. Of particular importance was the development of methods to obtain chemical data which in turn can be used to provide meaningful bases for modelling groundwater contamination. Water contaminated by vapor from laboratory-simulated in situ coal gasification was employed as a model polluted water. The solids used to sorb organics from this waster were subbituminous coal, non-activated coal char, activated coal char, and coal ash.
