TLDR
In monitoring the remediation of hydrocarbon-contaminated ground water by natural attenuation, subtle concentration changes in observation well data from the anoxic zone may be diagnostic of depletion of the intrinsic electron-accepting capacity of the aquifer.About:

Offshore oil spill response practices and emerging challenges.
TL;DR: The emerging challenges in cold and harsh environments are reviewed with recommendations due to increasing risk of oil spills in the northern regions from the expansion of the Arctic Passage.
Journal ArticleDOI
Depth-resolved quantification of anaerobic toluene degraders and aquifer microbial community patterns in distinct redox zones of a tar oil contaminant plume
TL;DR: This work characterized microbial community distribution across a high-resolution depth profile of a tar oil-impacted aquifer where benzene, toluene, ethylbenzene, and xylene degradation depends mainly on sulfate reduction and suggests that this biogeochemical gradient zone is a hot spot of anaerobic toLUene degradation.

Natural attenuation and enhanced bioremediation of organic contaminants in groundwater.
Kate M. Scow,Kristin A. Hicks +1 more
TL;DR: An area of intense scientific and practical interest is the biogeochemical and microbial processes determining the success of natural attenuation, biostimulation and/or bioaugmentation treatments for organic contaminants in groundwater.
Journal ArticleDOI
The relationship of total dissolved solids measurements to bulk electrical conductivity in an aquifer contaminated with hydrocarbon
TL;DR: In this paper, the authors investigated the vertical distribution of bulk conductivity, TDS, and specific conductance in groundwater, and concluded that biodegradation processes can impact both electrolytic and surface conduction properties of contaminated sediments and these two factors can account for the higher bulk conductivities observed in sediments impacted by hydrocarbon.

Biogeophysics: A new frontier in Earth science research
Estella A. Atekwana,Lee Slater +1 more
TL;DR: A recent review of the field of biogeophysics focuses on geophysical interrogation of microbial processes, including direct detection of microbial cells and biofilm formation, microbial metabolic by-products, microbe-mediated redox processes, and biogeochemical and microbemineral transformations as mentioned in this paper.

Statistical Methods for Environmental Pollution Monitoring
TL;DR: In this paper, the authors proposed three-stage sampling: simple random sampling, two stage sampling and three stage sampling, and two-stage and double sampling, respectively, to estimate the mean and variance from censored data sets.

Oxidation of aromatic contaminants coupled to microbial iron reduction
Derek R. Lovley,Mary Jo Baedecker,Debra J. Lonergan,Isabella M. Cozzarelli,Elizabeth J. P. Phillips,Donald I. Siegel +5 more
TL;DR: It is shown that in aquatic sediments, microbial activity is necessary for the oxidation of model aromatic compounds coupled to Fe(III) reduction, providing the first example of an organism of any type which can oxidize an aromatic hydrocarbon anaerobically.

Alternatives for Ground Water Cleanup
TL;DR: A 19-member committee of leaders in environmental engineering, hydrogeology, epidemiology, environmental economics, and environmental policy has written an ambitious book that broadly addresses the groundwater remediation problem as mentioned in this paper.

Crude oil in a shallow sand and gravel aquifer-III. Biogeochemical reactions and mass balance modeling in anoxic groundwater
Mary Jo Baedecker,Isabelle M. Cozzarelli,Robert P. Eganhouse,Donald I. Siegel,Philip C. Bennett +4 more
TL;DR: In this paper, the degradation of hydrocarbons affects the concentrations of oxidized and reduced aqueous species in the anoxic part of the contaminant plume that developed downgradient from the oil body.

The geochemical evolution of low-molecular-weight organic acids derived from the degradation of petroleum contaminants in groundwater
TL;DR: The geochemical evolution of low-molecular-weight organic acids in groundwater downgradient from a crude-oil spill near Bemidji, Minnesota, was studied over a five-year period (1986-1990).
