Message #49: March 2001
Welcome to TechDirect. March 2001 marks the fourth anniversary of
TechDirect. Over the last 48 months, I have tried to sift through and
identify the technical and policy resources that help you do your
work. While I am sure not everything in TechDirect that comes
across your desk is directly helpful, I continue to hope that you find
something useful in every message. TechDirect started in late
February of 1997 with about 1200 subscribers. I am very happy that
so many people are finding this a useful resource. Since the
February 1 message, TechDirect has 259 new subscribers for a total
of....10,161. I strive to make TechDirect current and relevant. If I fail
to do that, let me know. If you feel the service is valuable, please
share TechDirect with your colleagues. Anyone interested in
subscribing to TechDirect may do so on CLU-IN athttn://ciu-in.om/techdirect. All
48 previous TechDirect messages are archived there.
Mention of non-EPA documents or presentations does not constitute
a U.S. EPA endorsement of their contents, only an acknowledgment
that they exist and may be relevant to the TechDirect audience.

CLU-IN Studio Update. Five environmental response videos,
produced by the U.S. EPA Environmental Response Team (ERT),
have been added to the CLU-IN Studio site at hHD://d»-in.0m/st»di0. The

New Documents
NATO/CCMS Pilot Study Evaluation of Demonstrated and
Emerging Technologies for the Treatment of Contaminated
Land and Groundwater (Phase III): 2000 Annual Report (EPA
542-R-01-001). This document reports on the second meeting of the
Phase III Pilot Study. The Phase III study focuses on technologies for
soil and groundwater cleanup and addresses the issues of
sustainability, environmental merit and cost effectiveness and on
new emerging remediation techniques (January 2001, 246 pages).

weeks at (800) 490-9198 or (513) 489-8190 or fax to (513) 489-8695.
NATO/CCMS Pilot Study: 2000 Special Session - Decision
Support Tools (EPA 542-R-01-002). This report covers material
presented and discussed at at a special session on decision support
tools at a conference sponsored by the NATO Committee on the
Challenges of Modern Society in Wiesbaden Germany in June 2000.
The report contains nine papers on different aspects of decision
support tools that exist for remediation related activities. It also
contains a paper that captures the discussions from the closing
session of a European conference on decision support issues
(January 2001, 128 pages). View or download at http://clu-in.org/techpubs.htm .

Data Quality Objectives Process for Hazardous Waste Site
Investigations (EPA 600-R-00-007). This document, published by
the EPA Office of Environmental Information, is based on the
principles and steps developed in Guidance for the Data Quality
Objectives Process (QA/G-4) (EPA, 1994b) but is specific to
hazardous waste site investigations. This guidance is also consistent
with Data Quality Objectives Process for Superfund: Interim Final
Guidance (EPA, 1993) and Soil Screening Guidance: User's Guide
(EPA, 1996a). Although this document focuses on EPA applications,
such as site assessments under the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA) and the
Resource Recovery and Conservation Act (RCRA), this guidance is
applicable to programs at the state and local level (January 2000,
143 pages). View or download at http://clu-in.org/techpubs.htm .

of Metal Contaminated Soils (SFIM-AEC-ET-CR-99022). This
report was published by the U.S. Army Environmental Center and
the DOD Environmental Security Technology Certification Program
(ESTCP). This report provides an overview of the current
developmental status of electrokinetic remediation for metals
contaminated soils. Concerns with its in situ application and issues
that require further investigation are identified. The results of a field
demonstration conducted at Naval Air Weapons Station (NAWS)
Point Mugu are presented to illustrate the concerns with the in situ
application of this technology at its current stage of development
(July 2000, 30 pages). View or download at

Statistical Estimation and Visualization of Ground-Water
Contamination Data (EPA 600-R-00-034). This report, published by
the U.S. EPA National Risk Management Research Laboratory,
presents methods of visualizing and animating statistical estimates of
ground water and/or soil contamination over a region from
observations of the contaminant for that region. The primary
statistical methods used to produce the regional estimates are
nonparametric regression and geostatistical modeling (kriging). A
method is proposed for estimating the total amount of contaminant
present in a region (August 2000, 59 pages). View or download at
http://www.epa.aov/ada/download/reports/epa 600 rOO 034.pdf . For a hard copy, contact Kay
Cooper at (580) 436-8651 or fax (580) 436-8503.
Physical and Chemical Factors Affecting Contaminant
Hydrology in Cold Environments (ERDC/CRREL TR-00-21). This
report, produced by the U.S. Army Corps of Engineers, surveys
some of the physical and chemical effects of cold temperatures that
should be considered when developing a contaminant-transport
model. This discussion begins with a working definition of cold
regions for the purpose of contaminant hydrology modeling: an area
with appreciable frozen ground and with a substantial fraction of the
annual precipitation falling as snow. The chemical thermodynamics
of geochemical solutions below 0 Centigrade is reviewed. Particular
attention is placed on the physical -chemical properties of ice and
liquid water at subzero temperatures. Finally, models that estimate
the liquid water content and hydraulic conductivity of frozen ground
are discussed (December 2000, 37 pages). View or download at

Frozen Soil Barriers for Explosives Containment (ERDC/CRREL
TR-00-19). This report was produced by the U.S. Army Corps of
Engineers. The specific objectives of this work were to test the
efficacy of frozen barriers to restrain movement of RDX, TNT, and

picric acid through soils; test the concept of leaching contaminated
soils above a frozen barrier as a method for soil cleanup; and
compare the mobility and stability of explosives in an aged,
field-contaminated soil versus a freshly contaminated soil

The Tri-Service Site Characterization and Analysis
Penetrometer System-SCAPS: Innovative Environmental
Technology from Concept to Commercialization
(SFIM-AEC-ET-TR-99073). This report, published by the U.S. Army
Environmental Center, summarizes the development, field
demonstration and regulatory acceptance activities associated with
the SCAPS technologies that are used to detect, identify and
quantify subsurface contamination in soil and groundwater (January
2000, 48 pages). View or download at http://aec.armv.mil/prod/files/scaps99073.pdf .
CLU-IN's Site Characterization Pages Get a Make-over! Clu-ln's
Site Characterization section now splits the entries into two broad
categories: Technology Tools and Educational Materials.
Technology Tools offers information related directly to selection and
application. For example, the Field Analytical Technologies
Encyclopedia (FATE) is offered, and links to related pages
developed by other government agencies. Programs that specialize
in developing and evaluating new site characterization technologies
are featured, and links to sources of methods for implementing the
tools. The Educational Materials section provides background
information and guidance relevant to supporting and implementing
smart site characterization. It also includes papers that discuss the
policy implications of using innovative techniques and sections on
Brownfields, systematic planning, quality assurance, dynamic work
plans, statistics, and sampling considerations. Case studies illustrate
how these ideas have been applied in the real world, and share
lessons learned as site characterization practice undergoes this
modernization trend toward faster, cheaper, more accurate, site
investigations. See http://www.clu-in.org/char1 .cfm .
ETV Call for Technologies!! The Environmental Technology
