Sanitary Landfill Design, Leachate, and Gas Management
Fee: $1,595 / Online / Mar 11 - 12, 2027 / Course Code: 17-0328-ONL27
OVERVIEW
Please note, This instructor-led course has specific dates and times:
This course is held online over 2 days on the following schedule (All times in Eastern Time Zone): 10 am to 6 pm Eastern (Will include the usual breaks)
By the end of this course, you will be able to:
- Evaluate the factors that influence landfill siting, design, operation, and long-term performance
- Assess leachate and landfill gas management strategies to reduce environmental and operational risks
- Apply design principles for liner, cover, collection, and containment systems
- Interpret regulatory and environmental requirements that govern landfill development and operation
- Support landfill management decisions that protect groundwater, surface water, public health, and the surrounding environment
Description
Managing modern sanitary landfills requires balancing operational demands with increasingly stringent environmental, regulatory, and community expectations. Leachate generation, landfill gas migration, groundwater protection, site stability, and long-term environmental performance all present significant challenges throughout a landfill's lifecycle. Failure to effectively manage these risks can result in environmental impacts, regulatory non-compliance, increased operating costs, and public concerns.
This course provides a practical framework for understanding the design and management systems that support safe and effective landfill operations. You will examine the principles that govern landfill siting, containment, leachate collection, gas management, environmental monitoring, and post-closure performance while exploring the factors that influence long-term environmental protection. The course also reviews the regulatory and technical considerations that drive landfill design decisions and operational practices.
Through practical examples and case studies, you will strengthen your ability to evaluate landfill performance, assess environmental risks, support regulatory compliance efforts, and make informed decisions related to landfill design, operation, and environmental management.
