Abstract Major challenges exist in delineating bedrock fracture zones because these cause abrupt changes geological and hydrogeological properties over small distances. Borehole observations cannot sufficiently capture heterogeneity systems. Geophysical techniques offer the potential to image processes between boreholes. We used three‐dimensional cross borehole electrical resistivity tomography ( ERT ) a 9 m (diameter) × 15 well field high‐resolution flow transport fractured mudstone...
Transport of a nonionic surfactant (Triton X-100) at aqueous concentrations less than 400 mg/L through trichloroethene-contaminated sand-and-gravel aquifer Picatinny Arsenal, NJ, has been studied series laboratory and field experiments. In the laboratory, batch column experiments were conducted to quantify rate amount Triton X-100 sorption sediments. field, solution was injected into 26.5 L/min for 35-d period. The transport monitored by sampling analysis groundwater six locations...
This report describes a reconnaissance study of estuarine bed-sediment quality conducted June–October 2013 in New Jersey and York after Hurricane Sandy October 2012 to assess the extent contamination potential long-term human ecological impacts storm. The study, funded through Disaster Relief Appropriations Act (PL 113-2), was by U.S. Geological Survey cooperation with Environmental Protection Agency National Oceanographic Atmospheric Administration. In addition presenting...
Bioaugmentation is a promising strategy for enhancing trichloroethylene (TCE) degradation in fractured rock. However, slow or incomplete biodegradation can lead to stalling at byproducts such as 1,2-dichloroethene (cis-DCE) and vinyl chloride (VC). Over the course of 7 years, we examined response groundwater microbial populations bioaugmentation test where an emulsified vegetable oil solution (EOS®) dechlorinating consortium (KB-1®), containing established dechlorinator Dehalococcoides...
Abstract The U.S. Geological Survey's New Jersey and Iowa Water Science Centers deployed ultraviolet‐visible spectrophotometric sensors at water‐quality monitoring sites on the Passaic Pompton Rivers Two Bridges, Jersey, Toms River River, North Raccoon near Jefferson, to continuously measure in‐stream nitrate plus nitrite as nitrogen ( NO 3 + 2 ) concentrations in conjunction with continuous stream flow measurements. Statistical analysis of vs . discharge during storm events found...
Field studies were conducted under an induced gradient in a trichloroethene (TCE)-contaminated aquifer at Picatinny Arsenal, NJ, to study (a) the rate-limited desorption of TCE from sediments water and (b) effect surfactant (Triton X-100) on transport TCE. Clean was injected into contaminated for 206 day. Triton X-100 added 36-day period (days 36−71 start clean injection). The field examined by observing concentrations these two solutes four monitoring wells 3−9 m injection wells. These data...
Abstract The ability of diffusion samplers constructed from regenerated cellulose dialysis membrane and low density, lay flat polyethylene tubing to collect volatile organic compounds inorganic ions was compared in a laboratory study. Concentrations vinyl chloride, cis ‐1, 2‐dichloroethene, bromochloromethane, trichloroethene, bromodichloromethane, tetrachloroethene collected by both types reached equilibrium with the concentrations these test solution within three days. bromide iron seven...
Abstract A mass balance is formulated to evaluate the mobilization of chlorinated ethene compounds (CE) from rock matrix a fractured mudstone aquifer under pre‐ and postbioremediation conditions. The analysis relies on sparse number monitoring locations constrained by detailed description groundwater flow regime. Groundwater modeling developed site characterization identified fluxes formulate CE in volume exposed injected remediation amendments. Differences into out identify total mobilized...
Field characterization of a trichloroethene (TCE) source area in fractured mudstones produced detailed understanding the geology, contaminant distribution fractures and rock matrix, hydraulic transport properties. Groundwater flow chemical modeling that synthesized field information proved critical for designing bioremediation area. The planned involved injecting emulsified vegetable oil bacteria to enhance naturally occurring biodegradation TCE. showed injection will spread amendments...
Abstract The flowpath dependent approaches that are typically employed to assess biodegradation of chloroethene contaminants in unconsolidated aquifers problematic fractured rock settings, due difficulties defining discrete groundwater flowpaths such systems. In this study, the variation potential for with depth was evaluated a aquifer using two independent lines field evidence: (1) presence three biochemical prerequisites [electron donor(s), electron acceptor(s), and chlororespiring...

The U.S. Geological Survey and cooperators are studying chlorinated solvents in a fractured sedimentary rock aquifer underlying the former Naval Air Warfare Center (NAWC), West Trenton, New Jersey. Fractured-rock aquifers common many parts of United States highly susceptible to contamination, particularly at industrial sites. Compared 'unconsolidated' aquifers, there can be much more uncertainty about direction rate contaminant migration processes factors that control chemical microbial...
Abstract Significant microbial reductive dechlorination of [1,2 14 C] cis ‐dichloroethene (DCE) was observed in anoxic microcosms prepared with unamended, fractured rock aquifer materials, which were colonized situ at multiple depths two boreholes the Naval Air Warfare Center (NAWC) West Trenton, New Jersey. The lack significant corresponding water‐only treatments indicated that chlororespiration activity primarily associated core material. In these unamended microcosms, highest shallow...
Abstract The relative precision and accuracy of sampling analysis methods for the determination trace concentrations volatile organic compounds (VOCs) in ground water were compared. Samples collected from a well containing nanogram‐per‐liter (ng/L) to microgram‐per‐liter (μg/L) levels VOCs.

The dunes and the wetlands along southern shore of Lake Michigan are underlain by a complex aquifer system composed unconsolidated glacial, lacustrine, eolian deposits. Surficial dune, beach, glacial lacustrine sands compose an extensive surficial aquifer. underlying drift contains three major confined sand aquifers. Potentiometric hydrochemical data consistent with conceptual model in which regional intermediate flow systems, recharged end moraines south dune-beach complexes, discharge into...
