The Power Plant Toxics Measurements Database: Chemical Composition Information for the Electric Power Industry
For decades, power companies and other stakeholders have measured the toxic chemical content of the wastes from fossil-fuel power plants, but staff turnover can lead to loss of institutional memory regarding these measurements. To provide access to these data, EPRI created and maintains the Power Plant Toxics Measurements Database, an online resource with more than […]

Brine Encapsulation Laboratory Study: Ash Conditioning Compared to Engineered Encapsulation Strategies
Encapsulation is a process that binds waste materials into a form that minimizes their release into the environment. This report describes results of a laboratory study of five mix designs for wastewater encapsulation, including physical properties, mineralogical data, and environmental performance.

Field Evaluation of On-Line Selenium Analyzers for Monitoring Treated Flue Gas Desulfurization Wastewater
With more stringent U.S. Environmental Protection Agency limits on selenium in power plant flue gas desulfurization wastewater, it is desirable to monitor concentrations on a continuous or semi-continuous basis. Several vendors are commercializing selenium monitoring devices but field experience is limited. In this study, EPRI installed and operated two selenium analyzers—one from Aqua Metrology Systems […]
