What is a significant risk of not managing leachate properly?

The significant risk of not managing leachate properly is the contamination of water sources. Leachate is the liquid that drains or 'leaches' from a landfill containing various dissolved and suspended materials. If it is not contained and treated adequately, it can seep into nearby soil and waterways, leading to severe pollution. This can impact not only the immediate ecosystem but also the health of local communities due to the potential introduction of hazardous substances into drinking water supplies. Protecting water sources from leachate is crucial for environmental and public health, making proper management vitally important in waste management practices.
