Modeling Leachate Contamination and Remediation of Groundwater at a Landfill Site

Leachate contamination of an aquifer from a landfill sitewas simulated using the groundwater flow and transport model SUTRA developed by the U.S. Geological Survey. The model calibration was performed by spatially adjusting the hydraulic conductivity in order to capture the measured hydraulic head spatial variation and then by adjusting the dispersivity and porosity match the measured chloride ...

Case study - Groundwater remediation of a contaminated site using enhanced anaerobic bioremediation

Chlorinated solvents are a common threat to drinking water sources throughout the United States. While handling and disposal practices today are more closely regulated and monitored, this has not always been the case. With dry cleaners using tetrachloroethene (PCE) and industrial manufacturing facilities commonly using a variety of solvents from trichloroethene (TCE) to methylene chloride, past ...

Failure of Magnesium Peroxide to Remediate Petroleum Hydrocarbon-Contaminated Sites (PDF)

Researchers promote magnesium peroxide as a viable method to aerobically bioremediate petroleum hydrocarbons and restore groundwater quality. Suppliers claim that dissolved oxygen released in the saturated zone promotes biological growth for degrading a wide range of hydrocarbons dissolved in water and sorbed onto soil particles. Yet, staff with the CaliforniaRegional Water Quality Control Board, ...

An investigation and remediation of TNT contaminated soils.

An investigation and remediation of TNT contaminated soils and wastes was conducted at the Apache Powder Superfund Site in Cochise County, Arizona during 1999 and 2000. TNT contamination was most likely the result of salvage operations of World War I munitions. Characterized by a steep hillside and arroyo cutting through the wastes, the site offered challenges of stability, access, health and ...

Spolchemie site remediation and NanoRem field site application

Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the ...
