Coal Combustion Residuals in Receiving Lake Ecosystems: Trophic Transfer, Toxicity, and Tracers
… fields in the context of freshwater pollution by coal-fired power plant (CFPP) effluents, which contribute to the largest point source of environmental pollution in the United States and comprise a substantial threat to receiving ecosystems. CFPPs discharge the by-products of coal combustion, …

Geochemical and Isotopic Characterization of Coal Combustion Residuals: Implications for Potential Environmental Impacts
<p>Coal fired power plants are ubiquitous in the United States and most developed countries around the world, providing affordable electricity to consumers. In the US, approximately six hundred power plants generate 136 million tons of Coal Combustion Residuals (CCRs) annually, encompassing fly …

Engineering Characteristics of Coal Combustion Residuals and a Reconstitution Technique for Triaxial Samples
Traditionally, coal combustion residuals (CCRs) were disposed of with little engineering consideration. Initially, common practice was to use a wet-scrubbing system to cut down on emissions of fly ash from the combustion facilities, where the ash materials were sluiced to the disposal facility and …

Identifying water contamination from fossil fuel development using geochemical and isotopic fingerprints
… associated with the storage and disposal of coal combustion residuals, oil sands process-affected water, and oil and gas wastewater, as well as leaking of methane to groundwater in areas of hydraulic fracturing. In addition, contamination of water resources from natural (geogenic) sources has …

Radioactivity of Fossil Fuel Waste Products and Associated Environmental Implications
… activities of NORM have been measured in coal combustion residuals (CCRs) generated from coal combustion and oil and gas wastewater (OGW) drawn from both conventional and unconventional oil and gas producing wells. This dissertation characterizes the radioactivity associated with CCRs and …

Flow Behavior of Granular Soil and Impounded Fly Ash Slurries
… of an embankment dam around mine tailings and coal ash slurry impoundments typically results in a fast-moving flow of toxic waste that can carry for several miles with disastrous consequence. The most recent catastrophic tailing-dam failure took place on 25 January 2019, at Brumadinho, Brazil, …
