Message #109: March 2006

Welcome to TechDirect! Since the February 1 message, TechDirect
gained 318 new subscribers for a total of 24,452. This March issue of
TechDirect kicks off our tenth year keeping you informed of new
developments related to contaminated site clean-up. The growth in
subscribers suggests that we are on target. If you feel the service is
valuable, please share TechDirect with your colleagues. Anyone
interested in subscribing may do so on CLU-IN at	. All

previous issues of TechDirect are archived there. The TechDirect
messages of the past can be searched by keyword or can be viewed
as individual issues.

The purpose of TechDirect is to identify new technical, policy and
guidance resources related to the assessment and remediation of
contaminated soil, sediments and ground water.

Mention of non-EPA documents or presentations does not constitute
a U.S. EPA endorsement of their contents, only an acknowledgment

ITRC Site Investigation and Remediation for Munitions
Response Projects - March 14. This training provides an
introduction and overview of the processes, tools, and techniques
used in investigation and remediation. These concepts are illustrated
using an example munitions response site. Major steps in each
process are identified and key regulatory considerations discussed.
This training also identifies additional sources for more detailed
information on key aspects of investigation and remediation. State
regulators and others who need to understand the general
processes involved in these critical aspects of the munitions
response process will benefit from this training. For more information

and to register, see http://www.itrcweb.org Of http://clu-in.org/studio .

ITRC Design, Installation and Monitoring of Alternative Final
Landfill Covers - March 16. This training focuses on
evapotranspiration (ET) covers and the decisions associated with
their successful design, construction, and long-term care. For more
information and to register, see httn://www.itrcweh.om or http://clu-in.org/studio .

Revegetation and Restoration of an Oil Contaminated Wetland
in Northern New Jersey - March 30. This presentation will attempt

to show that a carefully supervised cleanup followed by a
scientifically driven monitoring program can be effective in removing
oil from a sensitive wetland habitat using the Green Pond Oil Spill
Removal project as the prime example. A monitoring program for
determining the success of the revegetation/restoration effort was
conducted. Species composition and productivity measurements
were an integral part of the parameters to measure the progress of
the effort to determine comparability between the remediated site
and undisturbed wetlands. The presentation will incorporate all that
has been learned from the removal activity in terms of How Clean is
Clean as applied to an oil contaminated fresh water wetland. This
information should be useful for decision makers, responders, and
consultants alike when faced with remediating disturbed or
contaminated habitats. For more information and to register, see

ITRC Constructed Treatment Wetlands - April 4. This course,
developed by the Interstate Technology and Regulatory Council
(ITRC), is based on Technical and Regulatory Guidance for Treating
Storm Water and Wastewater Using Constructed
Treatment Wetlands (WTLND-1). It describes the physical, chemical,
and biological mechanisms operating in wetlands treatment
systems, the contaminants to which they apply, the characteristics of
sites suitable to treatment in this fashion, and relevant regulatory
issues. For more information and to register, see h»n//wwwitrnwRhnm or

ITRC Perchlorate: Overview of Issues, Status, and Remedial

Options - April 6. Improved analytical methodology has increased

the known extent of perchlorate contamination in the U.S. A variety

of remediation technologies are currently commercially available and

being used for perchlorate remediation. This training,

based on ITRC's Perchlorate: Overview of Issues, Status, and

Remedial Options (PERC-1), explains why perchlorate is a hot topic

in the environmental community including up-to-date information on

sources, occurrences, toxicity and exposure,

regulatory status and remediation alternatives. For more information

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 (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 (December 2005, 26 pages). View or download

Characterization, Design, Construction, and Monitoring of
Bioreactor Landfills (ALT-3). This report was published by the
Interstate Technology and Regulatory Council (ITRC). It is intended
primarily for decision makers associated with the plan development,
review, and implementation of bioreactor landfills. The decision
makers include, at a minimum, regulators, owners/operators, and
consultants. This document focuses on the decisions and facilitating
the decision processes related to design, evaluation, construction,
and monitoring associated with bioreactor landfills (February 2006,

111 pages). View or download at http://www.itrcweb.ora/Documents/ALT-3.pdf .

Report on Results of the 2004-2005 Double-Blind Laboratory
Evaluation Program. During 2004 and 2005, the Massachusetts
Department of Environmental Protection (MassDEP) conducted a
large double-blind laboratory evaluation study, involving 19
commercial laboratories that provide the majority of analytical
support services to parties assessing and cleaning up hazardous
waste sites in Massachusetts. A double-blind study is one in which a
laboratory is unaware that they have been sent samples that contain
known concentrations of contaminants. The study was undertaken
by MassDEP as part of a multi-year/multi-component data
enhancement effort, in order to obtain a direct, real world sense of
data quality and reliability in its waste site cleanup program
(December 2005, 30 pages). View or download at

website are collected using information from technical journals,
conference proceedings as well as information obtained from
technology vendors and site managers. The project profiles contain
information about relevant site background, the types of
contaminants treated, type of vegetation used, phytotechnology
mechanisms, planting date, project size, location, cost, monitoring
and performance results, as well as points of contact and references.
This website can be used as a networking tool (each profile has a
contact) to provide past solutions and lessons learned to new sites
with similar contaminants and climate. See

Technology News and Trends - February 2006 (EPA
542-N-06-001). Technology News and Trends is a periodic
newsletter focusing on advancements in remediation and
characterization technologies. This issue features articles on a
pilot-scale bioreactive permeable reactive barrier wall that removed
metals from a groundwater plume within a year; a project where
zero valent iron (ZVI) clay soil mixing treated DNAPL at 35 foot
depth; electrical resistive heating removed 48 tons of PCA DNAPL in
six months; and thermochemical processes converted contaminated
sediment into clean construction material (February 2006, 6 pages).

Identity and Distribution of Residues of Energetic Compounds
at Military Live-Fire Training Ranges (ERDC TR-05-10). This
report was published by the U.S Army Corps of Engineers Engineer
Research and Development Center. A series of field sampling
experiments was conducted at 27 military firing ranges in the United
States and Canada to provide information on the identity and
distribution of energetic munitions constituents. Different types of
ranges were studied, including hand grenade, antitank rocket,
artillery, bombing, and demolition ranges. Both firing points and
impact areas were studied. Energetic compounds (explosives and
propellants) were determined and linked to the type of munition used
and the major mechanisms of deposition (November 2005, 69

pages). View or download at http://www.crrel.usace.armv.mil/librarv/pub06fvo.htm .
