Lead, chromium, arsenic, zinc, cadmium, copper, and mercury are the most common metal contaminants found on remediation project sites (US EPA, October, 2000). Cyanide is a common inorganic contaminant as well. Metal concentrations in excess of established health guidelines have been shown to create significant health risks to humans. ...
Water from three existing wells combines together with an average uranium concentration of over 40 ug/L, exceeding the EPA MCL of 30 ug/L. ...
In conclusion, H. verticillata biomass showed good potential as an adsorption material for the removal of uranium contaminants in aqueous solution. ...
Problem/Task: The groundwater in this region is contaminated with natural uranium, often above the EPA maximum contaminant level of 30 ppb uranium. ...
Low–grade uranium ore is mined and processed in India since the early 1970s. To adhere to the regulatory compliance monitoring of external gamma level, radon and long–lived alpha activity of ore dust is carried out in uranium mines. Apart from this, surface contamination is also monitored in radiologically important areas of ore processing plant. ...
Problem/Task The groundwater in this region is contaminated with natural uranium, often above the EPA maximum contaminant level of 30 ppb uranium. ...
The concentrations of the analysed elements (Sc, Mn, Co, Ni, Cu, Zn, Ga, Y, Cd, In, Tl, Pb, Th, U) were measured using ICP–MS in each sequential extraction step (exchangeable, reducible, oxidation and residual) and after a total digestion procedure.Keywords: fractionation, trace elements, soils, ICP–MS, Kazakhstan, uranium, soil contamination, environmental ...
Challenge In 2003 an area behind the hot cells in Building 2026 at the Oak Ridge National Laboratory (ORNL) was flooded with highly contaminated liquids when a liquid low level waste pipe became clogged. The main contaminants of concern are uranium and plutonium. Transferrable contamination levels are in the 1,000,000 ...
The community water system has a raw water uranium concentration of 118 parts per billion well above the EPA maximum contaminant level of 30 parts per billion. The uranium treatment system is rated for a maximum design flow of 200 gpm. ...
Bioremediation of uranium was investigated in microcosm experiments containing contaminated sediments from Oak Ridge, Tennessee to explore the importance of electron donor selection for uranium reduction rate and extent. ...
The biogeochemistry related to iron- and sulfate-reducing conditions influences the fate of contaminants such as petroleum hydrocarbons, trace metals, and radionuclides (i.e., uranium) released into the subsurface. An understanding of these processes is imperative to successfully predict the fate of contaminants during bioremediation scenarios. A ...
