Parallel In Situ Screening of Remediation Strategies for Improved Decision Making, Remedial Design, and Cost Savings

  title={Parallel In Situ Screening of Remediation Strategies for Improved Decision Making, Remedial Design, and Cost Savings},
  author={Rolf U. Halden and Kristin McClellan and Tomasz Kalinowski},
Abstract : This report summarizes the development and demonstration of a new tool for remedial design, the in situ microcosm array (ISMA). It may serve potential end users as a general guide on how to utilize the ISMA technology in the design and interpretation of in situ feasibility studies. Before in situ remediation can be implemented at a hazardous waste site, bench-scale or fieldscale feasibility studies are required. These are typically conducted in static batch-bottle microcosms, while…

Performance of the In Situ Microcosm Technique for Measuring the Degradation of Organic Chemicals in Aquifers

An in situ microcosm (ISM) consists of a stainless steel cylinder isolating about 2 L of the aquifer and is equipped with valves allowing for loading and sampling from the ground surface. During the

Assessing the correlation between anaerobic toluene degradation activity and bssA concentrations in hydrocarbon-contaminated aquifer material

The assessment of biodegradation activity in contaminated aquifers is critical to demonstrate the performance of bioremediation and natural attenuation and to parameterize models of contaminant plume

A Device for In Situ Determination of Geochemical Transport Parameters 2. Biochemical Reactions

Chemical and biological reaction rates are required in estimating migration rates of many reactive contaminants in ground water, and as input data for mathematical models. Reaction rates must be

Activity and Diversity of Sulfate-Reducing Bacteria in a Petroleum Hydrocarbon-Contaminated Aquifer

The combination of push-pull tests with molecular methods provided valuable insights into microbial processes, activities, and diversity in the sulfate-reducing zone of a PHC-contaminated aquifer.

Single‐Well, “Push‐Pull” Test for In Situ Determination of Microbial Activities

A single‐well, “push‐pull” test method is proposed for the in situ determination of microbial metabolic activities in ground‐water aquifers. The method consists of the pulse‐type injection (“push”)

Molecular Assessment of Inoculated and Indigenous Bacteria in Biofilms from a Pilot-Scale Perchlorate-Reducing Bioreactor

This study demonstrated the feasibility of post hoc analysis of frozen biofilms following completion of field remediation studies and revealed that FISH was more sensitive than RISA profiling in detecting possible survivors from the initial inoculum.

Bacterial community analysis of shallow groundwater undergoing sequential anaerobic and aerobic chloroethene biotransformation.

The study shows that bacterial community structure is related to groundwater geochemistry and that Alphaproteobacteria are enriched in locales where cis-DCE removal occurs and is shown to coincide with oxygen influx in hydrocarbon-containing groundwater near the source area.
