Designing, Assessing, and Demonstrating Sustainable Bioaugmentation for Treatment of DNAPL Sources in Fractured Bedrock

  title={Designing, Assessing, and Demonstrating Sustainable Bioaugmentation for Treatment of DNAPL Sources in Fractured Bedrock},
  author={Charles E. Schaefer and Craig Lavorgna and Michael D. Annable and Erin B. White},
Abstract : Bioaugmentation was applied to treat the DNAPL sources present in the fracture zones that were targeted for investigation using the partitioning tracer testing. Nine months of active treatment (using groundwater re-circulation with electron donor and nutrient delivery) was followed by a 10-month rebound period. While enhanced dissolution of the DNAPL sources was observed in both the shallow and deep fractures intervals, a greater extent of DNAPL mass removal (approximately 100 ) was… Expand


Bioaugmentation for treatment of dense non-aqueous phase liquid in fractured sandstone blocks.
Results indicate that bioaugmentation may be a viable remedial option for treating DNAPL sources in bedrock with significant dechlorination of PCE and growth of Dehalococcoides spp. Expand
Dense Nonaqueous-Phase Liquid Architecture in Fractured Bedrock: Implications for Treatment and Plume Longevity.
Results confirmed that the partitioning tracer testing was able to identify and quantify low levels of residual DNAPL along flow paths in hydraulically conductive fractures and suggest that the elevated PCE groundwater concentrations observed in the fractures likely are due to the presence of the residualDNAPL sources.

A remediation performance model for enhanced metabolic reductive dechlorination of chloroethenes in fractured clay till.
The model is developed to simulate field observations of a full scale bioremediation scheme in a fractured clay till and thereby to assess remediation efficiency and timeframe and it is demonstrated that dechlorination may be limited to narrow bioactive zones in the clay matrix around fractures and sand stringers.

Biologically enhanced mass transfer of tetrachloroethene from DNAPL in source zones: experimental evaluation and influence of pool morphology.
These laboratory-scale experimental results suggest that biotechnologies may be effective remediation strategies for depletion of source zones within pool transition zones. Expand
Dissolution of an emplaced source of DNAPL in a natural aquifer setting.
Field-scale dissolution of a multicomponent DNAPL (dense nonaqueous-phase liquid) source intentionally emplaced below the water table is evaluated in a well-characterized natural aquifer setting. TheExpand
Bioreactive Barriers: A Comparison of Bioaugmentation and Biostimulation for Chlorinated Solvent Remediation
A side-by-side comparison of bioaugmentation, biostimulation, and a recirculation-only control was implemented in a chloroethene-contaminated aquifer. The objective was to develop a contaminant massExpand
Inoculation of a DNAPL source zone to initiate reductive dechlorination of PCE.
The results of this research indicated that adding dechlorinating cultures may be useful in the application of source zone bioremediation but that dechlorination beyond cis-DCE may be limited to regions downgradient of the source zone. Expand
Field-Scale Evaluation of Bioaugmentation Dosage for Treating Chlorinated Ethenes
A field demonstration was performed to evaluate the impacts of bioaugmentation dosage for treatment of chlorinated ethenes in a sandy-to-silty shallow aquifer. Specifically, bioaugmentation using aExpand
Mass and flux distributions from DNAPL zones in sandy aquifers.
At three industrial sites in Ontario, New Hampshire, and Florida, tetrachloroethylene (PCE) and trichloroethylene (TCE), released decades ago as dense nonaqueous phase liquids (DNAPLs), now formExpand
Microbial activity and distribution during enhanced contaminant dissolution from a NAPL source zone.
Results demonstrate that microbial growth within NAPL source zones is possible, provided that contaminant concentrations remain below levels toxic to the dechlorinating organisms, and that microbialrowth can result in significant bioenhanced NAPl dissolution. Expand
