A Field Method to Quantify Chlorinated Solvent Diffusion, Sorption, Abiotic and Biotic Degradation in Low Permeability Zones
The objective of this project is to develop and test a field method capable of concurrently quantifying site-specific contaminant diffusion and degradation rates and sorption coefficients in low-permeability zones. The project focuses on developing the method for application to trichloroethene (TCE) contamination in fine-grained sedimentary rocks, where sorption capacity is expected to be significant, reduced iron minerals that promote abiotic degradation are common, and biological activity in the matrix is expected to be minor. USGS and University at Buffalo, Prof. Richelle Allen-King, Principal Investigator, began working together on this project in 2015.
A Comparison of Pump-and-Treat, Natural Attenuation, and Enhanced Biodegradation to Remediate Chlorinated Ethene-Contaminated Fractured Rock Aquifers
The objective of this project is to evaluate and compare chlorinated volatile organic compound removal and destruction from the well-characterized NAWC site by three remediation technologies — Pump and Treat (P&T), Monitored Natural Attenuation (MNA), and Enhanced Bioremediation (EB) — and to better understand the hydrogeologic and biogeochemical mechanisms that control contaminant removal by P&T and destruction by MNA and EB in fractured rock.

Demonstration and Validation of a Regenerated Cellulose Dialysis Membrane Diffusion Sampler for Monitoring Groundwater Quality and Remediation Progress at DoD Sites
This project demonstrated the use of low-cost, regenerated cellulose (dialysis) bag samplers for measuring a broad range of soluble contaminants and other chemical parameters in groundwater and determined the shortest appropriate equilibration period. This research at NAWC has expanded use of diffusion bag sampling to reduce costs at NAWC and other sites in fractured and unfractured media.

Investigating the Sensitivity of Emerging Geophysical Technologies to Immobile Porosity and Isolated DNAPL and Dissolved/Sorbed VOC Mass in Fractured Media
Lee Slater, Rutgers University
This project will determine the sensitivity of two emerging geophysical technologies—nuclear magnetic resonance (NMR) and complex resistivity (CR)—to immobile porosity and contaminant mass in the immobile pore space. This approach will permit both assessment of fine-scale contaminant mass around fractures and geophysical method performance across a range of geological settings from clastic to crystalline fractured rock, spanning the east to west coasts of the United States.

Demonstration of a Fractured Rock Geophysical Toolbox for Characterization and Monitoring of DNAPL Biodegradation in Fractured Rock Aquifers
The objective of this project is to demonstrate a method for characterization and monitoring of dense non-aqueous phase liquid (DNAPL) biodegradation (including free and dissolved phase) in fractured rock aquifers based on a fractured rock geophysical toolbox (FRGT).Information and publications at Rutgers

Development of Flexible Liners for High Resolution Subsurface Characterization
Carl Keller, FLUTe™
One objective of this project is to demonstrate and validate a liner-based method for rapidly measuring hydraulic heads along open boreholes in fractured-rock aquifers. The project is also testing liner-based methods for profiling water quality in the rock matrix in fractured-rock boreholes.
Rapid Assessment of Remedial Effectiveness and Rebound in Fractured Bedrock
Charles Schaefer, CDM Smith (formerly at CB&I, Shaw Environmental)
The overall objective of this project is to develop and evaluate a novel “Push-Push” remedial assessment technique, coupled with compound specific isotope analysis (CSIA), for use as a rapid and cost-effective means to assess the limits of in situ remediation in fractured bedrock systems.

Coupled Diffusion and Reaction Processes in Rock Matrices: Impact on Dilute Groundwater Plumes
The overall objective of this project is to measure and evaluate the impacts of bedrock structure and mineralogy on the persistence and diffusive flux of trichloroethene (TCE) from rock matrices to groundwater. The impact of oxidation fronts (generated naturally or via in situ chemical oxidation) between the fracture and matrix on these processes will be investigated, and TCE dechlorination kinetics via ferrous iron minerals within the rock also will be evaluated.

DNAPL Removal from Fractured Rock Using Thermal Conductive Heating
Carmen Lebrón, Naval Facilities Engineering Command (ret.)
The objective of this project was to demonstrate and validate a DNAPL remediation technique for fractured bedrock sites and to provide Department of Defense remedial project managers and site owners guidance on (1) When does it make sense to attempt aggressive remediation? and (2) What type of performance is to be expected from an aggressive technology application such as thermal conductive heating?

Demonstration and Validation of a Fractured Rock Passive Flux Meter
Kirk Hatfield and Mark Newman, University of Florida
The objective of this project is to demonstrate and validate the fractured rock passive flux meter (FRPFM) as new technology that measures the magnitudes and directions of cumulative water and contaminant fluxes in fractured rock aquifers.
