  • Natural Attenuation

    Introduction: Natural subsurface processes such as dilution, volatilization, biodegradation, adsorption, and chemical reactions with subsurface materials are allowed to reduce contaminant concentrations to acceptable levels. Natural attenuation is not a 'technology' per se, and there is significant debate among technical experts about its use at hazardous waste sites. Consideration of this ...

  • Innovative approach to unforeseen site conditions – case study

    The Crater Resources Quarry 3 Remediation site was a former limestone quarry that was later used as a disposal site for Waste Ammonia Liquor (WAL) generated by the coke making facility at a steel mill. The WAL contained water, ammonia, and small amounts of various hydrocarbons formed during the coking process. Coking operations shut down by the mid 1980's and discharge into the quarry ceased. The ...

  • Natural Attenuation in Soils

    Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...
