Evaluation of a Horizontal Well
Background: Air Sparging Air sparging is an in-situ remediation technology where air is injected into the saturated zone of an aquifer. It is an alternative to conventional ex-situ pump and treat systems for remediation of contaminated ground water. It is necessary to understand the pattern of air flow that will occur in the subsurface in order to determine the optimal placement, number, and ...

Bioaugmentation is a cost-effective and sustainable remediation alternative
Selecting a remediation alternative that is compatible with the natural soil and ground water conditions is not only a more sustainable approach, but leads to significant savings. Comparison between bioaugmentation and other remediation methods in the five recognized sustainability criteria demonstrates the advantages of bioaugmentation. While this paper is nota complete quantitative analysis, it ...
