2019 Robert G. Hennes Lecture/April Seattle ASCE Geotech Meeting

ABSTRACT

The lecture will briefly review several U.S. waste fill stability failures that occurred during the timeframe of the early 1980s to mid-1990s, that being the period during which modern landfill engineering materials and design approaches first emerged in response to governmental regulations, and the lessons learned during that period. Notwithstanding those lessons, waste fill failures continue to occur. Several failures from the current decade are reviewed and it is concluded that 20 to 30 years after the earlier timeframe, facility owners and the geotechnical practitioners designing those facilities are re-learning the earlier lessons, while at the same time there are new lessons to learn related to evolving waste streams and operating practices at many U.S. facilities. The lecture will conclude with an evaluation of the current state of practice for U.S. landfill design, construction, and operation, and several recommendations to improve the practice.
