Description:
Concern is rising over emissions of hazardous chemicals to the subsurface from waste management facilities, encompassing treatment, storage, and disposal of waste. The study of barriers used in engineering these facilities against release includes examination of geo-membrane liners (Gms). A test system has been developed that allows a uniquely comprehensive approach to applying comprehensive load, displacement, and fluid head; all simultaneously and individually adjustable. The membrane is tested and exposed in a manner more reflective of field conditions than in other tests reported in the literature. It remains to make use of these capabilities to reveal new information concerning waste-liner compatibilities. This work explores the interactions of high density polyethylene liner material with fuel, solvent, metal-containing, and TCLP-type leachate wastes, correlating modulus data from stress-strain and cyclic testing with differential scanning calorimetry and ultraviolet spectrophotometry. The ability to test a range of waste-liner interactions in a reasonable period of time, and in a manner that has direct relevance to field conditions, may yield findings that have increased significance in design activities.Publications and Presentations:
