Special USTfields Announcement
On July 1, 2002, the U.S. EPA announced the selection and funding
of forty new USTfields pilots. The USTfields Initiative was created by
the Office of Underground Storage Tanks (OUST) to address
brownfields sites with petroleum contamination from underground
storage tanks (USTs). Brownfields are idle or underutilized facilities
or properties that are actually or perceived to be environmentally
contaminated. USTfields are abandoned or underused industrial and
commercial properties where redevelopment is complicated by real
or perceived environmental contamination from underground storage
tanks. Each pilot was awarded up to $100,000 of Leaking
Underground Storage Tank (LUST) Trust funds to assess and clean
up petroleum-contaminated sites. See more information on the
USTfields program and the forty new pilots at http://www.epa.aov/oust/ustfield .
Upcoming Live Internet Seminars
Remediation System Evaluation and Optimization of Pump and
Treat Projects - July 16. The objective of this presentation is to
enhance current understanding of the Remediation System
Evaluation (RSE) process and optimization tools available to site
managers of pump and treat systems. RSEs aim to improve the
efficiency of operation and maximize the remedy's effectiveness by
identifying ways to reduce O&M costs, shorten closure time, verify
clear goals and exit strategy, and assure equipment is adequately
maintained. Pump and treat systems have been operating for two
decades and this experience has led to large gains in knowledge
and understanding. For more information and to register, see or

New Documents
Ground Water Sampling Guidelines for Superfund and RCRA
Project Managers (EPA 542-S-02-001). This document provides
sampling guidelines primarily for ground-water monitoring wells
which have a screen or open interval with a length of ten feet or less
which can accept a sampling device. A summary of current and/or
recommended ground-water sampling procedures is provided.
These guidelines were developed by the Superfund/RCRA Ground
Water Forum and incorporate comments from ORD, Regional
Superfund hydrogeologists, and others. These guidelines are
applicable to the majority of sites, but are not intended to replace or
supersede regional and/or project-specific sampling plans. These
guidelines are intended to assist in developing sampling plans using
the project-specific goals and objectives (May 2002, 53 pages). View

Proven Alternatives for Aboveground Treatment of Arsenic in
Groundwater (EPA 542-S-02-002). This issue paper, developed for
EPA's Engineering Forum, identifies and summarizes experiences
with proven aboveground treatment alternatives for arsenic in
groundwater, and provides information on their relative effectiveness
and cost. The four technologies included in the report are
precipitation/coprecipitation, adsorption, ion exchange, and
membrane filtration. The report describes the theory and operation
of each technique, available project-specific performance and cost
data, and limitations. The report also discusses special
considerations for retrofitting systems to meet the lower arsenic
drinking water standard (maximum contaminant level or MCL) of 10
ug/l (June 2002, 63 pages). View or download at http://clu-in.org/techpubs.htm .

Perchlorate Screening Study: Low Concentration Method for
the Determination of Perchlorate in Aqueous Samples Using Ion
Selective Electrodes. This report was prepared by the US Army
Corps of Engineers for EPA under the EPA Measurement and
Monitoring Technologies for the 21st Century (21M2) initiative (see
http://clu-in.org/21m2). The project resulted in a field method to
measure perchlorate concentration in ground water. The method,
which uses an ion selective electrode, has a method reporting limit
of 15 |jg/L and a detection limit of 3 |jg/L. The California advisory
level for perchlorates is 18 |jg/L. The method is subject to some
interference from bromide, chloride, and nitrate (October 2001, 172
pages). View or download at http://clu-in.org/techpubs.htm .
Role of Background in the CERCLA Cleanup Program (OSWER
9285.6-07P).	This document, produced by EPA's Office of Solid
Waste and Emergency Response (OSWER) clarifies the U.S. EPA
preferred approach for the consideration of background constituent
concentrations of hazardous substances, pollutants, and
contaminants in certain steps of the remedy selection process, such
as risk assessment and risk management, at Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA
or "Superfund") sites. To the extent practicable, this document may
also be applicable to sites addressed under removal actions and
time-critical actions. In general, the presence of high background
concentrations of hazardous substances, pollutants, and
contaminants found at a site is a factor that should be considered in
risk assessment and risk management (April 2002, 15 pages). View

Risk Assessment Guidance for Superfund, Part D (Publication
9285.7-47).	RAGS Part D complements the guidance provided in
Parts A, B, C, and E and presents recommended approaches to
standardize risk assessment planning, reporting, and review. Part D
guidance spans the CERCLA remedial process from project scoping
to periodic review of the implemented remedial action, approach
consists of three basic elements: Use of Planning Tools, Continuous
Involvement of EPA Risk Assessors, and Information Transfer to a
National Superfund Risk Data Repository (December 2001, 250
pages). Download in sections at http://www.epa.aov/superfund/proarams/risk/raasd/tara.htm .

VOC Off-Gas Treatment Technologies Database. This online
resource was developed by the Naval Facilities Engineering Service
Center. This system assists site managers in choosing options for
VOC Off-gas Treatment. It includes technologies that are emerging,
developing and mature. It also includes a cost estimator that

In Situ Enhanced Source Removal (EPA 600-C-99-002). This
report was produced by the EPA National Risk Management
Research Laboratory. The objective of this report is to document
research findings that suggest remedial objectives are technically
achievable in a reasonable time frame. The program demonstrated
in the field the effectiveness of emerging technologies using side by
side comparisons in controlled experiments. The performance of
each approach was compared to "pump-and-treat" technology to
normalize the variability at the site. The first site selected for
evaluation was Operable Unit 1, Hill Air Force Base, Utah, USA. To
view the report, see http://www.epa.aov/ada/research/src remed2.html . The report is also
available on CD ROM, contact Kay Cooper at (580) 436-8651 or fax

Surfactant-Enhanced Aquifer Remediation (SEAR) Design
Manual (TR-2206-ENV). This report was published by the Naval
Facilities Engineering Service Center. This design manual is
intended to provide background information and specific guidance for
technical personnel who would like to evaluate and apply in situ
surfactant flooding or surfactant-enhanced aquifer remediation
(SEAR) at sites contaminated with dense nonaqueous-phase liquid
(DNAPL) such as chlorinated solvents. This volume covers feasibility
issues and design aspects of the technology and the second volume
(Implementation Manual) will cover field implementation including
system setup and operations (April 2002, 112 pages). View or

data management at large industrial sites. This report provides
summary information from the workshop (May 2002, 43 pages).
