What is the primary concern regarding leachate in landfill management?

The primary concern regarding leachate in landfill management is the contamination of water supplies. Leachate is the liquid that percolates through waste and comes into contact with it, resulting in the dissolution of various substances, including harmful chemicals and pathogens. If leachate is not managed properly, it can infiltrate the surrounding soil and groundwater, posing significant risks to both drinking water sources and aquatic ecosystems.

Contamination of water supplies is especially critical because it can lead to serious public health issues, such as exposure to toxic substances and diseases. Ensuring that leachate is adequately treated and contained is essential for protecting environmental health and maintaining the safety of water resources. Effective leachate management practices, such as utilizing liners, leachate collection systems, and treatment technologies, are vital to mitigate these risks.
