WRD Geochemical Studies at the Norman Landfill
|
Understanding subsurface transport and biodegradation of contaminants in leachate from the Norman Landfill is applicable to forecasting the fate of contaminants released from the 1000s of landfills near rivers across the Midwest. An aspect of evaluating degradation and attenuation reactions requires evaluation of the abundance and reactivity of phases in alluvium contacting the leachate. Ferric oxides and sulfate minerals are reactive constituents in the alluvium that affect terminal electron accepting processes. In addition, clay minerals and carbonates influence the composition of leachate through cation exchange and water-rock reactions. This study will characterize the composition, mineralogy, and reactivity of solid phase constituents of the alluvium down gradient of the landfill. The information will be shared with microbiologists, aqueous geochemists, hydrologists, and other scientists conducting research at the site to collaboratively develop a comprehensive understanding of important processes and their implications for contaminant transport. |
