Background Document on Bottom Liner Performance in Double-Lined Landfills and Surface Impoundments

摘要

The background document presents and discusses in detail the data on performance of bottom liners for hazardous waste landfills and surface impoundments and discusses in detail as described in the 'Notice of availability of information and request for comments' published in the Federal Register on April 17, 1987 (12566-12575). The document presents data comparing the performance of compacted soil and composite bottom liners with respect to: (1) leachate collection efficiency; (2) leak detection capability; and, (3) leakage both into and out of the bottom liner. The document contains a significant bibliography of literature related to the performance of liners.
