Coal Ash

Working for the US Department of Energy National Energy Technology Laboratory, Frontier GeoSciences has developed several methods for assessing Coal Combustion Products (CCPs), including fly ash and flue gas desulfurization (FGD) solids and slurries. These tests were designed to mimic specific end uses for CCPs in order to better understand the potential mobility of mercury and other trace metals from CCPs into the environment.

Testing Available for CCPs
Test	Procedure	Final Use
Volatilization - low temp	40°C for 30 days	Soil fill / Landfill
Volatilization - mid temp	190°C for 60 min	Asphalt / Wallboard
Volatilization - high temp	1200°C for 5 min	Cement
Microbial Methylation	Batch reactor with D. propionicus	Soil fill / Landfill / Impoundment
Chemical Leaching	Tumbling, pH 4.2 with H₂SO₄ and HNO₃	Simulates precipitation/ runoff from any use

By taking advantage of our expertise in this area, you can:

Assess the impact of mercury control technology on CCP quality
Determine potential impacts to your CCP market
Monitor your end product for trace metal mobility
Identify environmental impacts of coal ash ponds
Prevent future liabilities relating to trace metals impacts
