          HIGHLIGHT/
          HIGHLIGHT/ OF THE JPRING 2OO4 TECHNICAL JUPPORT PROJECT (T/P) MEETING
For their Spring 2004 meeting, EPA's Technical Support Project (TSP) teamed for the first time with the National
Association of Remedial Project Managers (NARPM) Annual Training Conference in Miami Beach, May 24-28. The
three forums of the TSP—the Engineering, Federal Facilities, and Ground Water Forums—participated in NARPM's
plenary sessions as well as the technical sessions and training. About a dozen forum members also served as instructors
for the training. Through their participation at NARPM, the TSP hoped to foster stronger ties with RPMs to further their
goal of improving technical outreach and transfer within the regions. During the Tuesday morning plenary session, Rich
Steimle (OSWER), Headquarters' point of contact for the TSP, provided an overview of TSP to conference participants.
This overview included how to contact the Office of Research and Development's (ORD) Technical Support Centers for
technical assistance as well as updates on forum activities, such as the development and availability of technical issue
papers. Mavis Kent (Michigan DNR),  a state representative to the Ground Water Forum, summarized the work of the
Interstate Technology and Regulatory Council (ITRC) on technical guidance, training, and conferences (http://
www.itrcweb.org). The forums also met individually in business sessions to discuss current and future forum activities.
This newsletter highlights these activities.  For more information on the topics highlighted, please contact your regional
TSP representative listed at the end of this newsletter.

                                site-specific experiences with
                                delineating DNAPL source areas. A wide
                                range of sites were represented. Sites
                                were contaminated with a variety of
                                chlorinated solvents and creosote and
                                included both known and unknown
                                source areas—from small to large and
                                shallow to deep. The subsurface
                                geology at the sites ranged from
                                uniform to complex and from
                                unconsolidated deposits to fractured
                                bedrock formations. A variety of
                                characterization and treatment methods
                                were implemented at these sites with

     Next Meeting

     The Fall 2004 TSP meeting is tentatively scheduled for the week of
     October 18th in Sacramento, California. The theme of this meeting likely
     will be California's list of Emerging Contaminants in Drinking Water,
     which include perchlorate, 1,4-dioxane, and arsenic. Presentations
     would include treatment technologies for these contaminants, and field
     trips will be arranged to McClellan Air Force Base and Aerojet General
     Corporation to view ground-water remediation projects for TCE,
     radiological contaminants, and perchlorate. If you are interested in
     participating in this meeting, contact your regional forum representative
     listed at the end of this newsletter.

for Source Depletion? (EPA/600/R-03/
143), which is now available on the
web at http://www.epa.gov/ada/pubs/
reports.html. The report suggests that
source depletion is justified if the
source is less than 20 feet deep, less
than 0.1 acre, and the value of the
property is greater than $lM/acre.
Source depletion may also be justified if
remedial action objectives other than
MCLs are acceptable to all parties. The
report concludes that the source cannot
always be cleaned up to MCLs, but
there may be other reasons to address
the source zone.

Dave Jenkins (Region 4)  reported on
the success  of using Color Tec
colorimetric gas detector tubes for
assessing the presence of TCE in soil
cores, while drilling wells at an
electroplating site in Florida. The
screening  test was used to determine
the best depths to set monitoring well
screens. To  screen a sample.
investigators filled a 40-mL vial one-
third full of soil and one-third full of
distilled water. The vial was placed in a
hot water  bath for  30 minutes. A
vacuum pump was used to extract air
from the headspace through a needle
and into the detector tube. A color
change in the reagent indicated the
presence of TCE. The Color Tec tubes
are also sensitive to DCE and vinyl
chloride, but the tubes will
underestimate the presence of
chlorinated VOCs if BTEX are present
in the sample. Field experiments
showed that chlorinated VOCs could
be detected using the  Color Tec tube
directly in the RotoSonic sample bag
in a manner similar to screening a
RotoSonic-drilled core with a PID or
FID. This method allows the
investigator to keep up with progress
of the drill rig. Furthermore, it reliably
shows zones where chlorinated VOCs
are not detected (reportedly down to 8
ppb),  and  can detect the most
contaminated vertical segment in a
plume. Dave's abstract and Power
Point® file will be posted soon on the
TSP's website at www.epa.gov/tio/tsp/
meetings.htm.

Andy Grassland (Region 2) provided
an update on the Ground Water
Forum's efforts to create a database of
Superfund and RCRA sites where low
detection level analyses for 1,4-dioxane
have been conducted. With data from
almost all of the regions, the database
currently contains 53 sites in 17 states.
The forum  discussed appropriate next
steps and concluded that it should: 1)
pass the information to interested
parties at EPA Headquarters and in the
states;  and 2) prepare a short writeup
that can be  used in the regions to
increase the awareness of this
emerging issue.

Ken Lovelace (Headquarters/OSRTI)
announced that the Ground Water Task
Force,  a workgroup established under
EPA's "One Cleanup Program," has
posted two  option papers for review on
their website  (http://gwtf.clu-in.org/
papers/default.cfm#options): 1)
Cleanup Goals Appropriate for
DNAPL Source Zones; and 2) Ground
Water Use,  Value and Vulnerability as
Factors in Setting Cleanup Goals. He
asked that the Ground Water Forum
and other interested parties to review
the option papers to determine whether
or not the papers comprehen-sively
identify the issues of national
stakeholders (described in the
"problem statements" section) and
which options they would prefer the
Agency to pursue to address these
issues.  The  task force will compile
comments (due July 31st) and develop a
set of recommendations to OSWER
management.

Federal Facilities Forum

The Federal Facilities Forum
conducted a regional "roundup" of hot
issues affecting federal facilities in each
EPA region. Renee Wynn then updated
the forum on  recent activities and
strategies implemented by the Federal
Facilities Restoration and Reuse Office
(FFRRO) to address these issues.
               [continued on page 3]

performance-based RODs, privatized
cleanup, FUDS, emerging
contaminants, and the Department of
Energy's Risk-Based End State
Initiative.

Stacie Driscoll (Region 3)
demonstrated a proposed streamlined
format for CERCLA RODs, which has
been presented to the Streamlining
Task Force for future consideration at
federal facilities. The format is
explained in a new manual, which is
accompanied by a navigable CD-ROM
containing the streamlined ROD with
links to reference documents for
further information. In addition to
being archived on CD-ROMs, RODs
developed in the new format can also
be web-based. Stacie raised the
possibility of streamlining other
documents, such as remedial action
construction closeout reports.

The Federal Facilities Forum discussed
plans to write an issue paper on
perchlorate contamination. The issue
paper, which will be drafted by Tetra
Tech, will focus on the treatment of
perchlorate (both in-situ and ex-situ
techniques), but will also touch on the
general chemistry of perchlorate  and
the appropriate analytical methods. The
target completion date for the issue
paper is Fall 2004.


Engineering Forum

Mike Gill (Region 9's ORD Hazardous
Substance Technical Liaison)
announced that the latest Engineering
Forum Issue Paper, Introduction  to
Energy and Production at Waste
Cleanup Sites (May 2004, EPA 542-S-
04-001), will be available on
www.cluin.org on July 1st. The paper.
which will help RPMs apply an energy
efficiency approach to waste site
cleanups, features descriptions of
cleanups at four sites: two sites
involving energy conservation/
reduction and two sites involving
energy production. There are plans for
a follow-up  software tool to
accompany the  issue paper. This tool
will be a web-based energy calculator
that allows RPMs to estimate energy
use at site cleanups. The calculator is
applicable to 13 different cleanup
technologies.

The Engineering Forum is pushing
ahead with its plans to update the
Remedial Design/Remedial Action
Handbook (June 1995, EPA 540/R-95/
059).  Once funding for the project is
lined  up, forum members plan to
update the handbook to better
accommodate the more recent "One
Cleanup Program" concept. The
updated handbook will use program-
neutral language to provide a general
scheme for design and construction
concepts, while providing web-based
references to reach  specific program
requirements.

Dave  Reisman (EPA National Risk
Management Research Laboratory
[NRMRL] in Cincinnati) reported that
NRMRL is updating five previously
published Engineering Bulletins on
bioremediation, remediation of PCBs.
in-situ chemical oxidation, mining
issues, and in-situ soil remediation.
Once  NRMRL and the Engineering
Forum have reviewed the updated
bulletins, they will make them available
for external review before final
publication.
     New Members

     The TSP is always seeking new
     members to participate in
     activities of the Ground Water,
     Engineering, and Federal
     Facilities Forums. If you are
     interested, please contact  your
     regional TSP representative or
     a forum co-chair listed at the
     end of this newsletter. A
     complete list of contact
     information is available at
     www. epa. go v/tio/tsp/
     member.htm.
Ed Mead (U.S. Army Corps of
Engineers) indicated that the Screening
Data Collection Paper he is developing
with the Engineering  Forum is ready
for a final review. The paper, which is
also being developed  into an ASTM
guide, will help RPMs to select and
obtain the required physical and
chemical treatment process design data
at contaminated sites  early  in the
investigation stage. The paper contains
tables summarizing what data to
collect for in-situ and ex-situ soil and
water treatment technologies, as well
as the corresponding  field and
laboratory analytical methods.
