Microbial Activity during Biodegradation and its Effects on Groundwater Velocity in a Contaminated Aquifer
… and biodegradation in the aquifer. Changes in groundwater velocity associated with biological activity, were measured with point velocity probes (PVPs) arranged into multilevel standpipes and installed into the flow gate. PVP results were compared with electromagnetic wave velocity measurements …

Computational Tools for Improved Analysis and Assessment of Groundwater Remediation Sites
Remediation of contaminated groundwater remains a high-priority national goal in the United States. Water is essential to life, and new sources of water are needed for an expanding population. Groundwater remediation remains a significant technical challenge despite decades of research into this …

Contaminant migration of oil-and-gas drilling fluids within the glaciated sediments of north-central North Dakota
… in and around the two disposal sites to obtain groundwater and pore-water samples. Vertical electrode sounding resistivity profiles were conducted at both sites utilizing 14 electrode spacings down to a depth of 100 feet (30.5 m). Sediment samples were obtained with Shelby tubes for x-ray …

Characterizing Groundwater Discharge from a Cobble Armored Streambed, Alder Creek, Ontario, Canada
Quantifying flow across the groundwater-surface water interface (GWSWIn) is necessary for a detailed understanding of the hydrological connectivity between groundwater and surface water, and for the effective management of water resources in general. Fluxes across the GWSWIn can be used to monitor …

In Situ Oxidation of 1,4-Dioxane with Persulfate-Based Oxidation Activated by Iron Minerals
Groundwater contaminant plumes of 1,4-dioxane (dioxane) and its co-contaminants (chlorinated solvents) have been found at many hazardous waste sites. There is increasing attention paid to the persulfate-based activation method for in situ degradation of organic contaminants due to its high …
