Title Development of a Protocol and a Screening Tool for Selection of DNAPL Source Area Remediation.
Publication Date May 2012
Media Count 44p
Personal Author N/A
Abstract Multiple technologies have been developed and applied over the past few decades for remediation of chlorinated solvents in the subsurface. The remediation of solvents in the form of dense non-aqueous phase liquids (DNAPLs) is particularly challenging. Factors such as geology, geochemistry, hydrogeology, the composition and distribution of the DNAPL, as well as the presence and absence of other contaminants, play a role in technology selection and performance. To date, despite a multitude of reviews on several individual technologies, no comprehensive studies have been completed that illustrate which technologies generally work best under specific site conditions and desired remedial outcomes or goals. The primary objective of the project was to develop a user-friendly screening tool that can be utilized by decision makers during the remedial technology selection or evaluation process to: (1) Evaluate potential technology performance at a particular site; (2) Evaluate potential technology performance in different geological strata at a complex site; (3) Aid in the selection of feasible technologies for a particular site based on desired performance metrics; and (4) Reduce the uncertainty of estimating and predicting remedial outcomes and implementation costs at DNAPL source zone sites.
