Summary:Total isolation of wastes in humid areas can not possibly be achieved. Some migration of leachate from wastes buried in the ground will always occur. Performance standards must be supplied by regulations which are applicable on a site-by-site basis rather than rigid criteria for site selection and design. Several factors should be taken into consideration when designing performance standards. These factors should include the categories, segregation, degradation and toxicity of the wastes; the hydrogeology of the site, which governs the direction and rate of contaminant transport; the attenuation of contaminants by geochemical interactions with geologic materials; and the rate of release of unattenuated pollutants to the surface or to the groundwater. An adequate monitoring system is a prime consideration. This monitoring system should test the extent to which the operation of the site meets performance standards and should provide sufficient warning if pollution problems are going to appear so that remedial steps can be taken in time. Over the past few years there has been a trend away from numerous, small disposal sites and toward fewer and larger sites. In essence the size of a disposal site should be based on the attenuation capacity of the geologic material, which has a finite, though generally not well-defined limit. For those wastes which are slowly degradable, engineering sites with leachate-collection systems appear to be only a temporary solution, as the leachate collected will also require final disposal.
