Geochemistry of an Abandoned Landfill Containing Coal Combustion Waste: Implications for Remediation, and flow regime (continuous flow vs. episodic wetting/drying) on effluent chemistry. Results indicated that the fluid composition (e.g., pH, redox, elemental composition) was closely associated to dissolved and/or gaseous oxygen content and wetting regime. Given these conditions, the use of a dry

Rare Earth Elements in Fly Ashes as Potential Indicators of Anthropogenic Soil Contaminations the higher end of the concentration range whereas, the concentrations of middle rare earth elements (MREE) (Sm and Eu) and heavy rare earth elements (HREE) (Lu) were closer to the lower end of the observed range for North American fly ashes. The concentrations of REE did not show any significant e

Potential Use of Fly Ash to Remove Cadmium from Aqueous Systemsmarginally increased with increasing amount of adsorbent used. Fitting of Cd adsorption data for the full range of metal concentrations was described by a Freundlich model with a moderate correlation coefficient (r = 0.63) while the adsorption phenomena was described well by Langmuir isotherms at mo

Arsenic Speciation in a Fly Ash Settling Basin Systemoportion of amorphous Fe, amorphous Al and amorphous aluminosilicates in depth sectioned samples of a sediment core taken from the ash basins. The concentration of As solubilized by these extractants was also measured. Surface water As concentrations were low with an average of 13 and 3 μg 1. determ

The soil monoliths represented upper solum horizons of an Alfisol and a Mollisol with contrasting macroporosity and organic carbon content. The soil colloids were fractionated from low ionic strength Bt horizons of Alfisols with montmorillonitic, mixed, and illiti

Second season data using a monoculture of corn showed no significant stimulation or inhibition of biomass, in contrast to findi
