In recent years, deep-well disposal has been the subject of much discussion and criticism. Of the latter, some has been justified as a result of misapplication, but most has been unwarranted. Nevertheless, a fear factor has been aroused concerning deep-well disposal which is unjustified if the technique is properly applied and operated. Unfortunately, the public has confused the misapplication of the technique with the technique itself.

Deep-well disposal is not advanced as a cure-all for problems related to waste-liquid disposal. Its use is relatively limited considering the wide divergence in chemical composition of wastes. However, if installations are properly conceived, constructed, and operated, and are installed in a suitable geologic setting, they can fulfill a need without creating other problems such as can occur with waste-retention basins, incineration, or possibly even with sludge disposal. At the least, the deep-well method removes the waste from the biosphere.

Because the capacity of potential receiving formations is enormous, but finite, unrestricted deep-well disposal should not be allowed. The use of a formation for this purpose in any specific area should be controlled. Control in this context includes the awarding of permits and the delineation of factors such as acceptable injection rates and pressures, materials of construction, and such tests and monitoring facilities as can be justified to insure the utility and safety of the installation.

If expertise on these matters does not exist in the state, then it should be empowered to employ such experts on a consulting basis or to use the services of experienced government agencies, such as the U.S. Geological Survey or others. In any case, the equitable application of reasonable regulations can operate only to the benefit of all.
