The book describes the design, construction, and maintenance of innovative ET covers for landfills and waste. The author discusses why several vegetative covers have failed and provides simple, inexpensive solutions. He examines the design and construction of ET covers and other methods, highlighting their differences and successful alternative construction methods. The text contains the first proposed performance measurements for conventional and innovative landfill covers based on the data collected at more than fifty-five sites. This data also provides the basis for an assessment of landfill cover performance, design, and the creation of the site-specific performance criteria presented in the.
