Waste Containment System Design Seminar
Sept. 15 and 16
8 AM – 3 PM ET
Understanding the Critical Role of Geosynthetic Materials
Waste Containment System Design “Digging Deeper into Geosynthetic Design Through the Assessment of Surface and Subsurface Flow, Available Technical Support Documents, and Concepts to Enhance Electrical Resistivity Testing”
Location: Crowne Plaza Hotel, Syracuse, New York
701 E Genesee St, Syracuse, NY 13210
About this 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. This seminar will also denote where significant documents and current practice information can be found to educate and support the work effort of geosynthetic users. The cost of many of these documents are free or of little cost to the user. Based on these documents, there will be a discussion regarding Construction Quality Assurance (CQA) testing, frequency, timing and expected quality of test results. Finally, there will be a review of design considerations that increase the effectiveness of Electrical Resistivity Testing of liner systems and discuss the dynamics of construction water trapped in the secondary leachate collection and removal system in order to effectuate better construction outcomes.
Key Seminar Elements
The seminar has been developed to provide participants with an overview of the latest environmental regulatory requirements relevant to the design, specification and construction of double-lined landfills as required under New York State’s recently revised Landfill Regulations, 6 NYCRR Part 363.
Starting with “Darcy’s Law”, the participants will be shown how the principles of surface and subsurface flows impacts the design process and how these pathways change over time. Although this discussion of flow pathways will mainly be reviewed within the landfill closure design applications, it will be shown that this same train-of-thought is applicable to some bottom liner design details. Examples and case histories will show the long-term impacts of various landfill closure design elements.
The participants will be shown where valuable technical information can be found to support their professional engineering design and CQA services. These documents are either free to the user or a minimal cost to the user (e.g. ASTM, GSI, IGS, etc.). There will be discussion on specific areas of ASTM standards and how this knowledge (along with knowledge of geosynthetic manufacturing) impacts factors-of-safety, CQA testing requirements and scheduling of tests prior to construction.
The participants will also be shown how specific sections of ASTM standards can impact the design engineer’s understanding of the test results. Digging deeper into the methods of manufacturing geosynthetic products and understanding how these materials are tested can allow for a greater understanding of the limitations and quality of the test results, and in some cases be used to better inform the design engineer and ensure a successful design outcome.
Participants will be provided with design considerations that increase the effectiveness of Electrical Resistivity Testing for liner defect location. Case studies from sites in New York State will be used to illustrate key concepts. Recent research on the dynamics of construction water in the leak detection layer will be presented, which shows that sustained flow from the leak detection layer can be caused by construction water drainage rather than by leakage through the primary geomembrane. This discussion includes how to distinguish leakage through the primary geomembrane from construction water flow and also how to prevent it.
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.
PE Professional Development Hours (PDH)
There will be 13 PDHs offered for New York State professional engineering continuing education credits for participating in this unique technical learning event. Attendance for the full duration of this Seminar is required to receive the 13 PDH credits.
