Cooling ponds need liners to prevent water from leaking into the surrounding soil and groundwater. Without a liner, water can seep through the pond's bottom or sides, potentially carrying contaminants from the power plant into the environment. Liners help to contain the water within the pond, ensuring that it stays in place for efficient cooling. This containment is particularly important when the water in the pond may have small amounts of chemicals or minerals from the cooling process.
Liners also prevent erosion and protect the structural integrity of the pond, especially in areas where the soil may be unstable or prone to seepage. The use of liners ensures that the pond operates as designed, reducing environmental risks and ensuring compliance with regulations that protect local ecosystems and water sources.
