Definition(s)
Treatment Zone
Treatment Zone―the soil profile in a land treatment cell that is located wholly above the saturated zone and within which degradation, transformation, or immobilization of E and P Waste constituents occurs. The treatment zone is subdivided as follows.- Waste Treatment Zone (WTZ)―the active E and P Waste treatment area consisting solely of the E and P Waste solids applied to a land treatment cell during the application phase, exists entirely above grade (original cell bottom), and whose actual depth depends on the solids content of the E and P Waste applied. For monitoring purposes the WTZ represents the 0-24" depth increment.
- Upper Treatment Zone (UTZ)―the E and P Waste/native soil (original cell bottom) interface in a land treatment cell where some disturbance occurs as a result of E and P Waste treatment/manipulation. For monitoring purposes, the UTZ represents the 24-36" depth increment.
- Lower Treatment Zone (LTZ)―the zone beneath the UTZ in a land treatment cell from approximately 36-54" (or to the top of the subsurface drainage system) which remains undisturbed throughout the life of a land treatment cell.
