A cover system is provided for waste sites and environmental closures, in which the cover system comprises a synthetic grass and an impermeable geomembrane that can be applied without the use of heavy earthwork equipment as temporary or final cover to control odors, erosion, gas migration and contaminate migration. The invention allows installation on very steep slopes and does not require the use of an extensive anchoring system to resist wind uplift or slope failure.

What is claimed is: 1. A cover system for waste sites, wherein the cover system comprises: A. a synthetic grass which comprises a composite of at least two geotextiles tufted with synthetic yarns; and B. an impermeable textured geomembrane which is comprised of a polymeric material, wherein the cover system is used in the absence of a vegetative soil support top cover and wherein the textured geomembrane is used with a synthetic drainage component. 2. A cover system as defined by claim 1 wherein the impermeable geomembrane is selected from the group consisting of high density polyethylene, very low density polyethylene, linear low density polyethylene or polyvinyl chloride. 3. A cover system as defined by claim 2 wherein the impermeable geomembrane is comprised of linear low density polyethylene. 4. A cover system as defined by claim 2 wherein the impermeable geomembrane is comprised of high density polyethylene. 5. A cover system for waste sites, wherein the cover system comprises: A. a synthetic grass which comprises a composite of at least two geotextiles tufted with synthetic yarns; B. an impermeable textured geomembrane which is comprised of a polymeric material; and C. a drainage system comprising a synthetic drainage component, wherein the cover system is used in the absence of a vegetative soil support top cover. 6. A cover system as defined by claim 5 wherein the impermeable geomembrane is selected from the group consisting of high density polyethylene, very low density polyethylene, linear low density polyethylene or polyvinyl chloride. 7.
