What is the minimum height above bedrock that landfill must be located?

Landfills must be located a minimum of 10 feet above bedrock to ensure adequate separation from potential groundwater contamination. This height is critical for several reasons. First, it allows for the installation of proper leachate management systems and drainage to prevent the seepage of contaminants into the water supply. Second, maintaining this distance helps to manage any potential gas emissions and gives a buffer for waste settlement, which is essential for maintaining the integrity of the landfill structure over time. By adhering to this minimum height requirement, environmental health specialists can better protect public health and the surrounding ecological environment from the risks associated with landfill operations.
