Journal ArticleDOI
In situ measurements of volatile aromatic hydrocarbon biodegradation rates in groundwater
TL;DR: Biodegradation rates and patterns were measured using an in situ microcosm in a crude-oil contaminated aquifer near Bemidji, Minnesota and isomer-specific degradation patterns were compared to observations from a multi-year study conducted using data collected from monitoring wells along a flowpath in the contaminant plume.
Journal ArticleDOI
Fluid budgets at convergent plate margins: Implications for the extent and duration of fault-zone dilation
TL;DR: In this paper, the authors used numerical models to investigate the long-term partitioning of expelled fluids between diffuse flow and flow along connected high-permeability fault conduits.
Journal ArticleDOI
Decadal surface water quality trends under variable climate, land use, and hydrogeochemical setting in Iowa, USA
Christopher T. Green,Barbara A. Bekins,Stephen J. Kalkhoff,Robert M. Hirsch,Lixia Liao,Kimberlee K. Barnes +5 more
TL;DR: In this paper, surface water quality was analyzed in 10 major Iowa Rivers and several decades of concentration and flow data were analyzed with a statistical method that provides internally consistent estimates of the concentration history and reveals flow-normalized trends that are independent of year-to-year streamflow variations.
Journal ArticleDOI
Natural attenuation strategy for groundwater cleanup focuses on demonstrating cause and effect
TL;DR: In the 20 years since cleanup of contaminated groundwater has been a high priority in the United States, recognition of both the scope of the problem and the technical difficulties involved has grown steadily Estimates of the number of hazardous waste sites where groundwater may be contaminated vary between 300,000 and 400,000 nationwide [NRC, 1994].
Journal ArticleDOI
A mass balance approach to investigating geochemical controls on secondary water quality impacts at a crude oil spill site near Bemidji, MN.
G.-H. Crystal Ng,Barbara A. Bekins,Isabelle M. Cozzarelli,Mary Jo Baedecker,Philip C. Bennett,Richard T. Amos +5 more
TL;DR: The results show that oil constituents other than BTEX, including n-alkanes and other aromatic compounds, play significant roles in plume evolution and secondary water quality impacts, and underscores the importance of non-aqueous phases.
