Solid and hazardous waste landfills are required by federal, state, and/or local regulations to cover waste materials prior to or as part of final closure. These final covers are only one element of landfill systems, which may include a liner or multiple liners, the actual waste material, a cover, run-on and run-off control features, security, groundwater monitoring networks, and settlement monitoring markers. This training course was developed to provide tools and resources when considering the application of alternative final landfill covers. Alternative final covers (AFCs) may be used on bioreactor landfills, conventional landfills, or other types of landfills. Types of AFCs are asphalt covers, concrete covers, capillary barrier covers and evapotranspiration (ET) covers. This training course and associated guidance documents focus on ET covers and the decisions associated with their successful design, construction, and long-term care.
