Recent research has expanded our understanding of the suitability of waste disposal in various hydrogeologic settings. Although more research is needed, our knowledge can provide a basis for preparing guidelines for action that will protect ground water from waste disposal practices. It is impossible, however, to prevent accidental spills, unlawful dumping, and ground‐water contamination or pollution resulting from some old, unregulated waste disposal practices. Therefore, more than 170 case histories of subsurface contamination or pollution were studied to evaluate the effectiveness of remedial action in different geologic environments. The case studies indicate that the severity and extent of ground‐water contamination is determined by (1) the hydrogeologic setting, (2) the nature of the contaminant, and (3) the effectiveness of regulatory action. Industrial wastes are the most common sources of ground‐water contamination. The most serious incidents are those that pollute or threaten water supplies and those that cause a fire or explosion. Once ground water is contaminated, remedial action is time consuming and expensive. Each incident must be handled as a separate problem. Although prompt action is essential to limit contamination and minimize remedial action, no strategies have been established for rapid response to contamination or pollution problems. Ground‐water contamination will continue, but its impact can be reduced. The role of hydrogeologists in regulatory agencies should be strengthened to provide proper evaluation of potential sources of contamination and to aid in remedial action when ground water is contaminated. Cooperative efforts to develop strategies will ensure proper handling of future emergencies.
