(c) "Leachate" is drainage from the waste or fluid resulting from the percolation of liquid through a waste substance (d) "Usable" ground or surface water includes potentially usable water. (e) "Hydraulic continuity" is a condition existing when fluid occupying an interstice of a saturated material is able to move under a head differential to adjoining interstices or surface channels containing fluid; (f) "Capillary fringe" is the partly saturated zone immediately above the water table in which water is held by capillary forces. (g) "Toxic" means lethal, injurious, or damaging to man or other living organisms. includi plants, domestic animals, fish and wildlife . (h) "Active life" is the period .of time required to achieve W stabilization of decomposing waste in a site such that leachate U or the rate of generation of gases is no longer a threat to water quality. e Article 2. Classification of Waste Disposal Sites Z 2510.. Class I Disposal Sites. Class I disposal sites are F. those at which complete protection is provided for all time for the quality of ground and surface waters from all wastes deposited therein and against hazard to public health and wild- z life resources. The followihg , criteria must be met to qualify a o site as Class1: (a) Geological conditions are naturally capable of pre- venting vertical, ,hydraulic continuity between liquids and gases emanating from the waste in the site and usable surface or ground waters (b) Geological conditions are naturally capable of pre- venting lateral hydraulic continuity between liquids and gases emanating from wastes in the site and usable surface or ground waters, or the disposal area has been modified to achieve such capability. (c) Underlying geological formations which contain rock :Fractures or fissures of questionable permeability must be permanently sealed to provide a competent barrier to the movement of 'liquids or gases from the disposal site .
