Abstract
The present invention is a method of preventing water from leaching solid waste sites by preventing atmospheric precipitation from contacting waste as the water flows through a solid waste site. The method comprises placing at least one drain hole through the solid waste site. The drain hole is seated to prevent waste material from entering the drain hole, and the solid waste site cover material is layered and graded to direct water to flow toward the drain hole and to soil beneath the waste site.
Claims19
A method of preventing leaching of solid waste sites having a top and a bottom, comprising:
- (a) placing at least one drain hole extending from a first portion near the top of the solid waste site, through the solid waste site, to a second position substantially below the solid waste site,
- (b) sealing the perimeter of each drain hole, and
- (c) directing percolating water toward each drain hole and beneath the solid waste site.
A solid waste site having a top and bottom, said solid waste site protected from leaching, comprising:
- (a) at least one drain hole extending from a first position near the top of the solid waste site, through the solid waste site, to a second position substantially below the solid waste site, and
- (b) a cover which is water permeable in a first direction and substantially water impermeable in a second direction perpendicular to the second direction, said cover being sloped toward said drain hole.
