Iron (Fe) is one of the most biochemically active and widely distributed elements important for biota human activities. Fe plays roles in biological chemical processes. redox reactions groundwater have been attracting increasing attention geochemistry biogeochemistry fields. This study reviews recent research into biogeochemical enrichment processes, including reduction, biotic abiotic oxidatio...

Biotransformation of dissolved groundwater hydrocarbon plumes emanating from leaking underground fuel tanks should, in principle, result in plume length stabilization over relatively short distances, thus diminishing the environmental risk. However, because the behavior of hydrocarbon plumes is usually poorly constrained at most leaking underground fuel tank sites in terms of release history, g...

The world experience of using electrical exploration methods in the study technogenic bodies is considered, particular: determining zoning tailings, groundwater migration routes and stability dams. ongoing research demonstrates high efficiency combining geophysics, geochemistry, hydrology. On example mining dumps located on territory Kemerovo region Republic Tyva, achievements interdisciplinary...

A polyphasic approach based on cultivation and direct recovery of 16S rRNA gene sequences was utilized for microbial characterization of an aquifer contaminated with chlorinated ethenes. This work was conducted in order to support the evaluation of natural attenuation of chlorinated ethenes in groundwater at Area 6 at Dover Air Force Base (Dover, DE). Results from these studies demonstrated the...

This study aims to evaluate the hydro-chemical characteristics of Ouargla, Algeria basin groundwaters harvested from Mio Pliocene aquifer. The covered 70 samples; physical parameters, potential hydrogen (pH), and electrical conductivity EC ?S.cm?1 were determined in situ, using a multiparameter; laboratory analysis included dry residuals DR (mg/L), calcium Ca2+ magnesium Mg2+ sodium Na+ potassi...

Please cite this article in press as: Ayotte, J.D., trace elements at water-supply wells. Appl. Geo The effects of human-induced alteration of groundwater flow patterns on concentrations of naturallyoccurring trace elements were examined in five hydrologically distinct aquifer systems in the USA. Although naturally occurring, these trace elements can exceed concentrations that are considered ha...

Since naturally occurring methane and saline groundwater are nearly ubiquitous inmany sedimentary basins, delineating the effects of anthropogenic contamination sources is a major challenge for evaluating the impact of unconventional shale gas development on water quality. This study investigates the geochemical variations of groundwater and surface water before, during, and after hydraulic fra...
