> New Documents and Web Resources

DNAPL Website. EPA's Office of Superfund Remediation and Technology Innovation
has released a website that compiles available information related to the cleanup of
dense nonaqueous-phase liquids (DNAPLs) at hazardous waste sites. This initial
phase addresses the most common DNAPL contaminants: chlorinated ethenes (e.g.,
tetrachloroethene and trichloroethene) and multi-component wastes (creosotes, coal

tars, and heavy oils). Future expansion may include ethers, halogenated alkanes,
polychlorinated biphenyls, and other chemicals that form DNAPLs. With the primary
focus on source zone cleanup, information is provided for available remediation
technologies, such as bioremediation, in situ flushing and oxidation, and thermal
processes. EPA will maintain the website by adding new resources as they become
available. The website was developed in response to a recommendation of the EPA
Ground Water Task Force (www.awtf.ciu-in.ora'). which identified a need for the creation of a
comprehensive compilation of DNAPL resources. View and use at http://www.ciuin.ora/DNAPL.

Brownfields Technology Primer: Vapor Intrusion Considerations for
Redevelopment (EPA 542-R-08-001). This primer is designed for land revitalization
stakeholders concerned about vapor intrusion, including property owners,
municipalities, and real estate developers. It provides an overview of the vapor
intrusion issue and how it can affect redevelopment. It also summarizes techniques for
quickly and cost effectively assessing the potential for vapor intrusion, as well as
techniques for mitigating it. The topics covered will familiarize stakeholders with
options for addressing vapor intrusion to help them communicate with their project
contractors and consultants (March 2008, 48 pages). View or download at

EPA Office of Research and Development Land Research Program. This site
provides information on the innovative science solutions being developed by the
program to preserve the nation's land, restore contaminated properties, and protect
public health from exposure to environmental contaminants. The site includes a
description of the program, fact sheets, science topic experts, links to ORD technical
support centers, research publications, research accomplishments, and links to tools,
models, and information. View and use at http://www.epa.aov/ord/irp/.

Procedures for the Derivation of Equilibrium Partitioning Sediment Benchmarks
(ESBs) for the Protection of Benthic Organisms: Compendium of Tier 2 Values for
Nonionic Organics (EPA 600-R-02-016). This equilibrium partitioning sediment
benchmark (ESB) document describes procedures to derive concentrations for 32
nonionic organic chemicals in sediment which are protective of the presence of
freshwater and marine benthic organisms. The equilibrium partitioning (EqP) approach
was chosen because it accounts for the varying biological availability of chemicals in
different sediments and allows for the incorporation of the appropriate biological effects
concentration. This provides for the derivation of benchmarks that are causally linked to
the specific chemical, applicable across sediments, and appropriately protective of
benthic organisms (March 2008, 75 pages). View or download at

Enhanced Attenuation: Chlorinated Organics (EACO-1). This report was produced
by the Interstate Technology and Regulatory Council (ITRC). Many sites with
chlorinated organic contamination in groundwater have gone through extensive
remedial evaluations and actions. The remedial alternatives for many of these sites
include high-energy treatments such as pump-and-treat systems. After years of
operation, the effectiveness of these high-energy processes has begun to diminish
without remedial objectives being met. Other more effective remedial alternatives need
to be implemented; however, there is a lack of guidance available to regulators and the
environmental community regarding how and when to transition these sites to
lower-energy remedial alternatives and eventually to monitored natural attenuation
(MNA). To answer this need, the ITRC Enhanced Attenuation: Chlorinated Organics
(EACO) Team developed this guidance, which includes a protocol to assist in a smooth
transition (or a bridge) between aggressive remedial actions and MNA (April 2008, 109

pages). View or download at http://www.itrcweb.ora/Documents/EACO-1 .pdf .
