Remediating explosive-contaminated groundwater by in situ redox manipulation (ISRM) of aquifer sediments.
In situ chemical reduction of clays and iron oxides in subsurface environments is an emerging technology for treatment of contaminated groundwater. Our objective was to determine the efficacy of dithionite-reduced sediments from the perched Pantex Aquifer (Amarillo, TX) to abiotically degrade the explosives RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine), HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7...
متن کاملArsenic Contaminated Groundwater and Its Treatment Options in Bangladesh
Arsenic (As) causes health concerns due to its significant toxicity and worldwide presence in drinking water and groundwater. The major sources of As pollution may be natural process such as dissolution of As-containing minerals and anthropogenic activities such as percolation of water from mines, etc. The maximum contaminant level for total As in potable water has been established as 10 µg/L. ...

ii I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. Abstract Arsenic is a known carcinogen, causing cancers of the skin, lungs, bladder and kidney. Current research suggests that drinking water is the mo...
متن کاملinvestigation of in-situ remediation of benzene and mtbe-contaminated groundwater by chemical oxidation using stabilized zero-valent iron nanoparticles (case study: southern tehran aquifer)
contaminated groundwater by gasoline spill is a worldwide environmental problem. gasoline contains methyl tert-butyl ether (mtbe) and benzene, which are the chemicals of concerns (cocs) among the gasoline components. mtbe is highly water soluble and has a low henry’s law constant and low soil adsorption co-efficient. therefore, mtbe can easily move through the soil and then accumulate, distribu...
متن کاملCase Study of Ex-situ Biological Treatment of Perchlorate-contaminated Groundwater
Groundwater in certain areas at Longhorn Army Ammunition Plant (LHAAP) (Texas) contains volatile organic compounds (VOCs) and perchlorate from past operations at the site. Groundwater from a Burning Ground and Landfill is currently being remediated by pumping the water from an interceptor collection trench system to the surface, removing VOCs and metals in an ex-situ treatment process, and disc...
