In this blog, we will focus on filter press dewatering and wastewater treatment solutions for coal ash. Coal fly ash is produced as a byproduct from the burning of coal in coal-fired power plants. It is one of the largest types of industrial waste generated in the U.S. There are literally hundreds of unlined coal ash ponds in the United States and, unfortunately, the contaminants from the ponds are leaking into waterways & groundwater, putting our nation’s drinking water supplies at risk.

Proper Coal Ash Treatment Solutions Are Needed To Address Potentially Toxic Contaminants in Coal Combustion Residuals
According to Earthjustice, an environmental law organization, coal ash – also known as Coal Combustion Residuals (CCRs) – is linked to serious human health problems.
Coal ash contains toxic contaminants like mercury, cadmium, and arsenic and without adequate coal ash remediation & proper wastewater management, these contaminants can pollute our waterways and groundwater, threatening our precious drinking water supplies and contributing to potential short-term & long-term human health issues. Long-term exposure to CCRs, for instance, may potentially lead to cardiac arrhythmias, kidney damage, liver damage, and various cancers.
Did You Know that in the United States there are literally hundreds of leaking coal ash ponds (or unlined sludgy basins) – typically next to coal-fired power plants. Such ponds, each typically spanning many acres, are often located close to communities and water bodies.
Based on the industry’s own data, more than 95% of the coal ash ponds in the United States are unlined.
Readers of this blog may well be aware of the large coal ash spills near Kingston, TN (2008) and Eden, NC (2014) which caused significant environmental & economic damage to waterways and communities. The TN incident spilled over a billion gallons of coal fly ash slurry. There were ~40 deaths and 250+ illnesses related to the cleanup, the largest industrial spill in US history.
Strengthening Protections: Ensuring Safe Disposal of Coal Ash Act
The EPA Administrator signed the Disposal of CCRs from Electric Utilities Final Rule on December 19, 2014 and it was published in the Federal Register in April 2015. This Rule finalized regulations to provide a comprehensive set of requirements for the safe disposal of CCRs from coal-fired power plants. Beginning in 2018, coal-fired electric utilities were required to publicly and transparently report groundwater monitoring data based on the CCRs Residuals Rule.
Currently, there is legislation recently introduced in the House of Representatives, Ensuring Safe Disposal of Coal Ash Act, to further strengthen the protections outlined in the 2015 Coal Ash Rule. This builds upon the CLEAN Future Act.
