Landfill sites should be located at least how far from streams, lakes or other surface bodies of water?

The guideline for locating landfill sites is designed to protect water bodies from potential contamination that can occur from waste materials. Generally, a distance of at least 200 feet from streams, lakes, or other surface bodies of water is recommended to mitigate the risk of leachate—liquid that drains or 'leaches' from a landfill—impacting these water sources. This distance is seen as adequate to ensure that any potential pollutants have time to naturally attenuate or are buffered away from direct entry into the water systems.

Establishing a buffer zone at this distance enhances environmental safety and is a common practice in waste management regulations to safeguard aquatic ecosystems and drinking water sources. By maintaining this minimum distance, regulatory frameworks aim to minimize the risk of groundwater contamination and ensure that any leachate is effectively managed before it can reach nearby water bodies. This practice helps to uphold public health standards and protect the environment.
