GEOPHYSICAL TECHNIQUES FOR SELECTION, ANALYSIS AND MONITORING OF WASTE DISPOSAL SITES

Groundwater contamination from waste disposal sites could be avoided with proper site analysis techniques. One of the major criterions for site selection should be the relative permeabilities at the site. In the case of hazardous waste disposal such as in uranium tailings operations, a waste disposal site should have extremely low permeability with no permeable hydrostratigraphic units included within the sequence which would carry contaminates away from the site. If it is not possible to find a site with these properties, then engineering safeguards must be designed into the waste disposal facility. In many cases, core recovery is not complete. In such cases, geophysical logs can provide a continuous in situ reading of subsurface parameters which affect seepage potential. Geophysical logs can be used as a very effective technology to eliminate the necessity of having to line an impoundment which is a very expensive operation. At other sites, the geophysical logs may indicate that lining is necessary because of the pressure of highly permeable units. This information could save an operator substantial amounts of money in the long run because seepage inhibitors could be designed into the initial impoundment construction. Groundwater contamination from waste disposal operations could be avoided with proper site analysis techniques. Contamination from disposal sites is carried down-gradient within permeable hydrostratigraphic units which can be located and delineated with a combination of drill holes, borehole geophysical logs, and surface geophysics. These same techniques are useful in the assessment and delineartion of existing contaminate plumes and provide cost-effective data for the design of withdrawal wells in the affected area. (Author)
