Update on the Waste Containment System Design Seminar 2020

Events | July 24, 2020 | By:

Due to the COVID-19 pandemic, we have decided to transition this year’s seminar to a virtual format. We will still deliver the same content as the in-person event and the same great materials will be available to all those who attend. Stay tuned for further details regarding the virtual event.


“Understanding the Critical Role of Geosynthetic Materials

About the Seminar

This technical training opportunity has been developed to provide attendees with a deeper working knowledge of surface and subsurface flows of stormwater impinging on landfill closures. This discussion will go beyond slope stabilization using the infinite slope formula. Various design approaches and details will be discussed to show how they either hinder or promote the long-term stability of the soil cover.

Who Should Attend?

Landfill design engineers, construction supervisors, landfill owners and operators, regulatory agency staff and public works and municipal engineers will all benefit from this seminar. This seminar is uniquely developed to benefit both the experienced as well as newly hired practitioners in the field of waste containment design and construction.


Principal instructor: Robert (Bob) Mackey, P.E. BCEE, principal, S2L Incorporated. Mackey is a past chair of ASTM D35 Committee on Geosynthetics with 35+ years of solid waste facility design experience. He is a former adjunct professor at the University of Central Florida, ASCE continuing education course instructor and ABET program evaluator for civil/environmental engineering programs.

Electrical leak detection instructor: Abigail Gilson, P.E., senior engineer, TRI Environmental Inc. has more than seventeen years of diverse civil engineering experience and is a registered civil engineer in multiple states including New York, where she resides. She spent the first part of her career as a containment facility design engineer and joined TRI in 2012 to focus solely on the implementation and innovation of electrical leak location technologies. She has more than fourteen years and 160 million square feet of electrical leak location experience. Her contribution to the field of electrical leak location includes numerous published technical papers, educational seminars, presentations worldwide, and chairing the ASTM committee for the recent revisions and additions to the ASTM Standard Guide and Practices.

Regulatory instructor: Robert Phaneuf, P.E., assistant director of New York State’s Department of Environmental Conservation’s Division of Materials Management, has worked in the field of solid waste management in a regulatory oversight role for more than 40 years. Phaneuf’s primary duties have included formulation of statewide solid and hazardous waste management policy and regulation including supervision of technical and administrative evaluations of applications to construct and operate solid and hazardous waste management facilities throughout New York State. Since 1988, Phaneuf has been a key member of the division’s rule-making team for the state’s solid waste management regulations.
