    An example of the potential use of a template site would be to generate first approximation costs for comparing different dense nonaqueous-phase liquid (DNAPL) treatment and removal technologies. Figure shows a plot plan for a sample template site used to compare costs for cleanup of a DNAPL spill of kg (1, lbs) of perchloroethylene. The removal was achieved by in situ chemical oxidation with Fenton's reagent that was injected into the subsurface through an array of injection wells. The removal of the DNAPL at Kings Bay has lowered the estimated time for site remediation from 35 years or more (with the previous pump-and-treat system) to approximately 5 years, and lowered.

[Dennis G Grubb; Nicholas Sitar. DNAPLs: Technologies for Characterization, Remediation, and Containment Chlorinated hydrocarbons are among the most common pollutants in groundwater and soils at Department of Energy (DOE) sites (Riley et al., ), as well as other contaminated sites across the United States (Pankow and Cherry, ).

DNAPL Site Remediation. Many technologies have been developed for source and plume treatment, all with specific advantages and limitations.

Selecting a treatment technology requires evaluating several factors, including technical site features (e.g., geology, hydrogeology, and contaminant levels), regulatory requirements, sustainability, and community stakeholder interests. The report includes 7 projects addressing cleanup of soil and groundwater using in situ bioremediation technologies, 4 case studies focusing on soil vapor extraction for treatment of halogenated volatile compounds, and 3 reports covering in situ soil and groundwater treatment using chemical oxidation/reduction technologies.

These DNAPL serve as persistent sources of dissolved phase contamination and are a major impediment to successful and cost-effective cleanup of sites.

Commonly used pump-and-treat remediation systems have not been effective in removing DNAPL from these subsurface source areas or in restoring down-gradient contaminated groundwater. This reference book published by Springer to help engineers and scientists better understand dense nonaqueous phase liquid (DNAPL) contamination of groundwater and the methods and technology used for characterization and remediation.

One of the mechanisms for the evaluation of innovative field-scale technologies for hazardous waste remediation is the Superfund Innovative Technology Evaluation (SITE) Program. The SITE Program is currently investigating approaches for the in situ treatment of contaminated sites.

The research includes innovative technologies for clean up of. Abstract. Contaminated sites can pose a significant risk to public health and the environment. Many different insitu or ex-situ remediation technologies have been developed throughout the years to mitigate the risk imposed by soil contamination.

These technologies may be contaminant and site by: There are two primary zones at DNAPL sites, the source zone and the plume zone. Remediation strategies for DNAPL sites can be divided into two categories: source removal or treatment and contaminated plume cleanup.

The main objective of source remediation is to reduce the mass, volume, or mobility of by: 5. On thermally enhanced remediation of DNAPL contaminated sites M. van Zutphen, Th.
