DNAPL Remediation: Selected Projects Where Regulatory Closure Goals Have Been Achieved (PDF) (900K, 52 pp, About PDF)

Order EPA 542-R-09-008

The purpose of this paper is to highlight sites where dense nonaqueous phase liquid (DNAPL) source reduction has been demonstrated as an aid in meeting regulatory cleanup goals. The presence of DNAPL in the subsurface can serve as a long-term source of dissolved contaminant plumes in groundwater, making it more difficult to reach regulatory closure. However, once the DNAPL source is addressed, residual groundwater plumes may be more amenable to treatment, including less aggressive techniques such as monitored natural attenuation (MNA) or bioremediation. This paper updates the document, DNAPL Remediation: Selected Projects Approaching Regulatory Closure, prepared in 2004 by providing more recent information on technologies and on five additional selected sites at which DNAPL source reduction technologies were applied.

The U.S. Environmental Protection Agency (EPA) Principles for Greener Cleanups outline the Agency?s policy for evaluating and minimizing the environmental 'footprint' of activities undertaken when cleaning up a contaminated site. Use of the best management practices (BMPs) identified in EPA's series of green remediation fact sheets can help project managers and other stakeholders apply the principles on a routine basis, while maintaining the cleanup objectives, ensuring protectiveness of a remedy, and improving its environmental outcome. Almost 495,000 releases of petroleum from federally regulated underground storage tanks (USTs) have been reported to EPA as of September 2010. Of these, over 93,000 UST site cleanups remain. The Association of State and Territorial Solid Waste Management Officials (ASTSWMO) estimates that cleaning up UST system releases costs the states approximately $700 million each year, in addition to federal expenditures under the Leaking Underground Storage Tank (LUST) Trust fund and costs paid by responsible parties. Use of green remediation BMPs to remediate these sites can help minimize the environmental footprint of cleanup activities and improve corrective action outcomes. The practices for UST cleanups are intended to complement rather than replace federal requirements for corrective actions (40 CFR Part 280, subpart F). The practices also may enhance state-administered UST programs, which have state-specific corrective action requirements.

The U.S. Environmental Protection Agency (EPA) Principles for Greener Cleanups outlines the Agency's policy for evaluating and minimizing the environmental 'footprint' of activities undertaken when cleaning up a contaminated site. Use of the best management practices (BMPs) recommended in EPA's series of green remediation fact sheets can help project managers and other stakeholders apply the principles on a routine basis, while maintaining the cleanup objectives, ensuring protectiveness of a remedy, and improving its environmental outcome. Historically, approximately one-quarter of Superfund source control projects have involved soil vapor extraction (SVE) to remove volatile organic compounds (VOCs) sorbed to soil in the unsaturated (vadose) zone. Air is extracted from, and sometimes injected into, the vadose zone to strip VOCs from the soil and transport the vapors to ex situ treatment systems for VOC destruction or recovery. Air sparging (AS) involves injection of air into contaminated groundwater to drive volatile and semivolatile contaminants into the overlying vadose zone through volatilization. SVE is commonly implemented in conjunction with air sparging to remove the generated vapor-phase contamination from the vadose zone.

Pilot Project to Optimize Ground Water Remediation Systems at RCRA Corrective Action Facilities: Summary Report and Lessons Learned (PDF) (242K, 26 pp, About PDF)

EPA Publication Number: EPA 542-R-04-018

Based on previous success with conducting independent optimization evaluations at Fund-lead pump and treat sites (i.e., those sites with pump and treat systems funded and managed by Superfund and the States), the EPA Office of Superfund Remediation and Technology Innovation (OSRTI) and the Office of Solid Waste (OSW) commissioned a study to pilot similar evaluations at facilities subject to corrective action under the Resource Conservation and Recovery Act (RCRA). During 2003 and 2004, independent evaluations were performed at five RCRA facilities by an independent EPA contractor. The Remediation System Evaluation (RSE) process developed by the U.S. Army Corps of Engineers was used. For each of the five sites, the RSE process included a review of site documents, a site tour to interview site stakeholders, and preparation of an RSE report. The RSE reports provided site background, summarized the findings from the site visit, and provided recommendations.

Pilot Project to Optimize Ground Water Remediation Systems at RCRA Corrective Action Facilities: Summary Report and Lessons Learned (PDF) (123K, 26 pp, About PDF)

Order EPA 542-R-06-001

Following the success with conducting independent optimization evaluations at Superfund-financed pump and treat (P&T) sites, the U.S. EPA Office of Solid Waste (OSW) and the U.S. EPA Office of Superfund Remediation and Technology Innovation (OSRTI) sponsored independent optimization evaluations in 2003 and 2004 at five facilities with pump and treat (P&T) systems regulated under the Resource Conservation and Recovery Act (RCRA). The Remediation System Evaluation (RSE) process developed by the U.S. Army Corps of Engineers was used. Based on the positive results of these RSEs and the consideration that many sites would receive a similar benefit from a streamlined RSE with a lower cost, OSRTI and OSW commissioned a new pilot study to develop and pilot a streamlined RSE process (or 'RSE-lite') that reduces the evaluation cost relative to a full-scale RSE. Four sites were selected by the EPA OSRTI and OSW to receive RSE-lites based on nominations provided by EPA project managers. Upon completion of the draft RSE-lite reports, one of the four sites was selected to receive a site visit and additional analysis to convert the RSE-lite into a full-scale RSE.

Terrestrial Carbon Sequestration: Analysis of Terrestrial Carbon Sequestration at Three Contaminated Sites Remediated and Revitalized with Soil Amendments (PDF) (5.1MB, 56 pp, About PDF)

Order EPA 542-R-10-003

This paper provides EPA's analysis of the data to determine carbon sequestration rates at three diverse sites that differ in geography/location, weather, soil properties, type of contamination, and age. The first site, located at high elevation in Leadville, Colorado, suffered from contamination due to mining. The site was amended with biosolid cakes, biosolids pellets, biosolid compost, and limestone starting in 1998. The second site, located in Stafford County, Virginia, had highly reduced, high-sulfur soils resulting from construction activities for an airport at the site. When exposed to air, these soils rapidly acidified, causing acid runoff that contaminated local streams. The site was amended with biosolids in 2002. The third site, Sharon Steel, is located at the border of Pennsylvania and Ohio and was contaminated through the application of by-products associated with manufacturing steel. At Sharon Steel, soil amendments were applied as part of a field demonstration project in 2008.
