ACKNOWLEDGEMENTS AND DISCLAIMER Geosyntec Consultants This detailed technical report was prepared by Geosyntec Consultants and funded by Waste Management, the largest waste management company in North America. Geosyntec Consultants would like to acknowledge the assistance of Waste Management in providing access to their databases, landfill information, and technical personnel. Geosyntec comprehensively reviewed the technical and peer-reviewed literature in order to provide an up to date evaluation of the regulatory oversight, engineering design, active management, routine maintenance, and long-term monitoring requirements associated with the modern managed solid waste landfill. The findings and conclusions of this report characterize the state-of-practice in terms of the systems and controls routinely implemented by the solid waste industry to protect the environment. However, this report is not intended as a substitute for thorough engineering and technical research with respect to any specific site and may not be relied upon for that purpose.
