NRMRL MONTHLY REPORT FOR SEPTEMBER 2004
Stephen G. Schmelling, Division Director
TECHNICAL ASSISTANCE
Solvents Recovery Service of New England (SRSNE), Inc. Site,
Region 1: On September 10, Ann Keeley (GWERD) provided
RPM Karen Lumino with review comments concerning a
feasibility study for the Solvents Recovery Service of New
England, Inc. (SRSNE) Site in Southington, CT. In general, the
documents were well done from the standpoint of technical content
and presentation. Issues discussed were the required amount of
electron donor to be injected into the ground water, problems
associated with the introduction of microorganisms into the
subsurface, and the response of indigenous organisms to chemical
oxidation and heat during remediation activities. It was pointed
out that Ann Keeley and others at GWERD have a publication in
this month's issue of Remediation Journal dealing with the effect
of heat and oxidizing chemicals on indigenous microorganisms at
Cape Canaveral.

Macalloy Corporation Site, Region 4: On September 2, Ralph
Ludwig and Steve Acree (GWERD) attended a kick-off meeting in
Charleston, SC, to discuss the initiation of full-scale remediation
activities at the Macalloy Corporation Site. Technical input was
provided on the proposed ground-water remedy involving the
injection of a ferrous iron based reductant into the subsurface.
Potential issues associated with the proposed ground-water remedy
and post-implementation monitoring were discussed as well as
scheduling and sequencing of activities. Also in attendance were
representatives from the South Carolina Department of Health and
Environment, the PRP and contractors, and EPA Region 4.
(R. Ludwig(GWERD)580-436-8603)
Yerington Mine-Anaconda Copper Co. Site, Region 9: During
August 25-26 David Jewett (GWERD) participated in meetings in
Yerington, NV, to discuss issues associated with the Yerington
Mine-Anaconda Copper Co. Site. In addition to a public meeting
on radionuclides in mine wastes, a technical workgroup focused on
a work plan review, BLM radionuclide sampling results, Health
and Safety Plan efforts, subsurface characterization concerns,
ground-water quality issues, and the revision of the community
relations plan. Other participants at the technical meeting included
USEPA Region 9, BLM, Nevada DEP, Yerington Paiute Tribe,
Walker River Paiute Tribe, BP/ARCO, Brown & Caldwell, and
SECOR. Also in attendance were representatives from the City of
Yerington, Lyon County, US Senator Reid's Office, and the local
and national press.

Carson Ground-Water Contamination RCRA Site, Region 9:On September 14, Steven Acree and David Jewett (GWERD), and
Noman Ahsanuzzaman, Mingyu Wang, and Rob Earle (Shaw
Env.) provided RPM Greg Lovato with a review of a proposed
modeling study at the Carson Ground-Water Contamination RCRA
Site in Carson, CA. In general, the description of the study was too
vague in most aspects, including discussions of objectives,
available data, and procedures, to allow a detailed review.
Discussed in detail were a number of issues including the
assumption of pseudo-steady-state flow, general head boundaries,
vertical hydraulic conductivity, calibration data, and model
selection.
(S. Acree(GWERD)580-436-8609/D. Jewett(GWERD)580-436-8560)
Port of Ridgefield Site, Region 10: During August 31 -
September 2, Eva Davis (GWERD) was in Seattle to discuss and
visit the Port of Ridgefield Site where steam injection is being used
for the remediation of creosote at a former wood treatment facility.
An earlier steam injection pilot test at the Wyckoff/Eagle Harbor
Site ran into technical problems associated with the treatment of
recovered chemicals. In addition to discussing the Wyckoff pilot
study report, a site tour of the Port of Ridgefield Site was held
including the steam injection field and above-ground treatment
facilities.

ONGOING RESEARCH
Field Sampling in Elizabeth City, NC. GWERD staff Cynthia Paul, Mary Sue McNeil and Chunming Su conducted an eight-day field sampling trip September 13-21 at the U.S. Coast Guard Center in Elizabeth City, NC. This sampling trip was in support of long term performance of permeable reactive barriers.
MEETINGS AND PRESENTATIONS
Eva Davis (GWERD) attended the 2004 USEPA/NGWA Fractured Rock Conference: State of the Science and Measuring Success in Remediation" September 13-15, in Portland ME. She made a presentation entitled "Steam Injection Into Fractured Limestone at Loring Air Force Base", and was co-author on a presentation entitled "A Simple Analytical Model for Heat Flow in Fractures: Application to Steam Enhanced Remediation Conducted in Fractured Rock."
Michael Brown, Associate Assistant Administrator, ORD, visited GWERD September 23 and made a presentation entitled "Creating Champions". He met with EPA staff to discuss the work done at this center and possible methods of communicating it to the media and the external community.
Donna Vincent Roa, ORD Public Affairs Director, met with several individual scientists September 23-24 to learn more about the work done at GWERD and the possibilities for news articles.
Robert Ford (GWERD) made an oral presentation for USEPA Region 6 in Dallas, TX, on September 30. The title of the presentation, authored by him, was "Monitored Natural Attenuation for Inorganic Contaminant Remediation in Ground Water."
COMMUNITY OUTREACH
GWERD staff Garmon Smith, David Walters and John Wilson gave fifteen Boy Scouts from Troop 13 a tour of the center on September 27. The visit satisfied part of their requirement to earn a merit badge.
