Use of Chemical and Isotopic Signatures to Distinguish Between Uranium Mill-Related and Naturally Occurring Groundwater Constituents at the Bluewater Disposal Site
… areas soil, stream sediments, surface water and groundwater. The Bluewater mill, a predominant mill within the GMD, disposed of tailings in unlined tailings piles causing widespread groundwater contamination. This study utilized Uranium-234/Uranium-238 (234U/238U) isotopic ratios in conjunction …

Distribution and Probable Sources of Nitrate in the Seymour Aquifer, North Central Texas, USA
… the spatial variability of nitrate and related groundwater constituents in 30 counties above the Seymour Aquifer, analyze temporal patterns of nitrate pollution, identify probable sources of pollution, and recommend water development strategies to minimize exposure to nitrate and reduce future …

Groundwater redox conditions at a petroleum contaminated site, Kuils River, South Africa : pathways for BTEX biodegradation
… of the hydrocarbons is taking place. Groundwater samples taken from 32 monitoring wells were analysed for NO₃-,NH₄+, Mn²+, Fe²+, SO₄²-, and ΣH₂S. Portable electrodes were used to make field measurements of electrical conductivity, redox potential, and pH. The variation and distribution …

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 …

The geochemistry of radioactive waste disposal
… of competing cations, typical of inorganic groundwater constituents, depended on: (1) Ni/Co:Mn+(Mn+ = competing cation) ratio, (2) nature of M^n+, (3) total solution ionic strength. The presence of organic material in groundwater is well documented, but its effect on cation sorption has not …

In-situ photocatalytic remediation of organic contaminants in groundwater
… reactor design, Honeycomb, for in-situ groundwater remediation. Photocatalysis, typically a pseudo first order advanced oxidation process, is initiated via the illumination of UVA light on the catalyst, i.e. titanium dioxide (TiO2). In the presence of oxygen, highly reactive oxidising …
