Michael Houlihan is a Senior Principal Engineer based in Maryland with more than 35 years of experience focused on industrial and municipal waste management, waste containment system design, geotechnical engineering, environmental remediation, revitalization of impaired properties, construction engineering, and litigation support, including expert-witness work. 


His recent projects include closing and remediating coal-ash disposal sites at electric-power generating stations; permitting and designing the 20-year expansion of the Cherry Island Landfill in Wilmington, Delaware; redeveloping the 2,000-acre Fresh Kills Landfill in New York City; and designing green infrastructure for stormwater management and reuse in Washington, DC. 

Mike leads projects and committee work related to landfill alternative cover technologies, disaster debris management, and long-term use of landfills. A key focus of his practice over the past several years was developing and applying approaches for containment, closure, and remediation of coal combustion residuals from electric power production.

To advance the state of the practice, Mike evaluates and applies innovative waste management technologies, serves on technical and policy committees evaluating landfill bioreactor and alternative cover technologies, and contributes to technical and regulatory guidance for the Interstate Technology Regulatory Council (ITRC) Alternative Landfill Technologies Workgroup.

In addition, he actively develops approaches to provide very-long-term care for impacted sites. He collaborates with regulators, planners, developers, and industry workers to develop analytical approaches to redevelop impaired properties while protecting human health and the environment. The results of the initial phase of Mike's work, which was performed for the Environmental Research and Education Foundation (EREF) study and titled "Evaluation of Post-Closure Care at MSW Landfills," was released in September 2006.
