Comparison of transport effects of perfluorinated and hydrocarbon surfactants on environmental co-contaminants
… Najee Simmons The use of groundwater as drinking water justifies efforts for the prevention and remediation of groundwater contamination by environmental pollutants. The inclusion of hydrocarbon surfactants (HCSs), at high concentrations, in a groundwater system has been …

Laboratory and Field Studies Directed toward Accelerating Arsenic Remediation at a Major US Superfund Site in New Jersey
… sites. Remediation of As contaminated groundwater by conventional methods, i.e. pump and treat (P&T), can be impeded by slow desorption of As from Fe and Al (hydr)oxides in aquifer solids. Through experimentation at different physical scales (grain, bench, and field scale), the …

Biosorption of uranium and its effect on uranium transport in groundewater
… as a remediation method for uranium-contaminated groundwater at U.S. Department of Energy sites with promising results. Although transport models have been improved to include variations in geochemical concentrations, reductive microbial processes, and adsorption of uranium to minerals, they do …

Laboratory denitrification using sediments from the Elk Valley Aquifer
<p> An experiment was conducted to determine if a decrease in the content of sulfides related to denitrification could be measured in the laboratory using sediments of the Elk Valley Aquifer in eastern North Dakota. The experiment entailed analyzing sediments for sulfides and solid organic carbon …
