Coal Ash Pond Liner Installer
A coal ash pond liner is a critical environmental safeguard used to contain coal combustion residuals (CCR), commonly known as coal ash. These liners prevent harmful chemicals and heavy metals—such as mercury, arsenic, and lead—from seeping into the surrounding soil and groundwater.

What Is a Coal Ash Pond Liner?
A coal ash pond liner is an impermeable barrier installed at the bottom of ponds used to store coal combustion residuals (coal ash) from power plants. These liners prevent the harmful components in coal ash, such as heavy metals and toxic chemicals, from leaching into the surrounding soil and groundwater.
Why Are Coal Ash Pond Liners Important?
Coal ash pond liners are essential for environmental protection. Coal ash contains hazardous materials like arsenic, mercury, and lead, which can contaminate groundwater and ecosystems if not properly contained. Power plants can safely store coal ash using pond liners and prevent these toxic substances from polluting the environment.
What Materials Are Used for Coal Ash Pond Liners?
Coal ash pond liners are typically made from high-density polyethylene (HDPE), polyvinyl chloride (PVC), or composite liners that combine synthetic and natural materials. These materials are chosen for their durability, chemical resistance, and ability to prevent leaks or seepage.
How Do Coal Ash Pond Liners Help Prevent Water Contamination?
Coal ash pond liners create a secure barrier that traps toxic chemicals and heavy metals within the pond, preventing them from seeping into groundwater or nearby water bodies. This containment is crucial for protecting drinking water supplies, aquatic life, and the broader environment from the harmful effects of coal ash.
Can Coal Ash Pond Liners Be Retrofitted to Existing Ponds?
Yes, coal ash pond liners can be installed in existing coal ash ponds as part of remediation efforts to bring older ponds up to modern environmental standards. Retrofitting a liner into an existing pond helps prevent future leaks and minimizes the environmental impact of coal ash storage.
