NRMRL MONTHLY REPORT FOR NOVEMBER 2005
Stephen G. Schmelling, Division Director
TECHNICAL ASSISTANCE
Ash Landfill, Seneca Army Depot, Region 2: On
November 18, Ralph Ludwig (GWERD) provided RPM
Julio Vasquez with a review of preliminary first-round
ground-water sampling results for a system of three mulch-
based biowalls at the Ash Landfill, Seneca Army Depot,
Romulus, NY. The biowall system is designed to
biologically treat TCE and its by-products through
reductive dehalogenation reactions. The first round results
were found to be too preliminary and inconclusive with
regard to system performance although indicator
parameters such as EH, alkalinity, sulfate and nitrate
concentrations within the biowalls, relative to up-gradient
locations, suggested reducing conditions had been
established. Vinyl chloride data was not presented and it
was suggested that this data be included in future
presentations.

Fike/Artel Superfund Site, Region 3: On October 14,
John Wilson (GWERD) provided RPM Katherine Lose
with review comments on two reports pertaining to in-situ
aerobic-based remedial technologies at the Fike/Artel
Superfund Site in Nitro, WV. Concerns were expressed
about the interpretation presented for some of the results
such as bromide tracer studies. Problems were also cited
with the monitoring well configurations, particularly with
respect to screens locations. Comments were offered with
respect to attempts to biodegrade the major contaminants of
concern and the delivery of oxygen and nutrients to ground
water containing the contaminants. A case history and
results of a similar treatability study conducted by GWERD
at another location were provided.

Hollingsworth Solderless Terminal Site, Region 4: In a
continuing technical assistance effort at the Hollingsworth
Solderless Terminal Site in Ft. Lauderdale, FL, Scott
Huling (GWERD) and Bruce Pivetz (Dynamac) provided
RPM Galo Jackson with review comments on a report
describing the operation and results of an in-situ enhanced
bioremediation pilot test. Potassium lactate was injected to
provide a substrate for microorganisms to create an
environment suitable for reductive chlorination. In the
November 22 response, it was noted that concentrations of
chlorinated compounds increased in many of the
monitoring wells by one to four orders of magnitude,
possibly due to the mobilization of previously undetected
contamination by the recirculation system. The persistence
or degradation of DCE and VC was not clear since only
one set of post-injection analytical results was in the report.
In addition, some observed geochemical changes during the
lactate injection and recirculation system operation were
unexpected, specifically, increases in DO and ORP.

ONGOING RESEARCH
Field Sampling at Minebank Run, MD. During November, Paul Mayer and Russell Neill (GWERD) completed the first post-restoration field sampling trip at Minebank Run, MD.
MEETINGS AND CONFERENCES
Chunming Su (GWERD) made a poster presentation, co- authored with Ralph Ludwig (GWERD), entitled "A mixed chemical reductant solution for treating hexavalant chromium in a chromite ore processing solid waste" at the Soil Science Society of America Annual MeetingNovember 6-10 in Salt Lake City.
Bart Faulkner (GWERD) attended the American Water Resources Association 2005 Annual Water Resources Conference in Seattle, WA, November 7-10. He made an oral presentation of an extended abstract entitled "Use of electrical resistivity probe for determination of hyporheic flow." Co-authors are Victor Murray (Shaw Environmental) and Sam Hobson (Oklahoma State University).
Elise Striz (GWERD) attended the Mid-Atlantic Stream Restoration Work Group Second Annual Conference at Berkley Springs, WV, on November 8-9. She presented an update on the Mine Bank Run stream restoration research project entitled, "An Evaluation of Stream Restoration Effectiveness in an Urban Watershed", which was co- authored with Paul Mayer (GWERD), Peter Groffman (IES), and Edward Doheny (USGS).
Paul Mayer and Steve Reynolds (GWERD) attended the annual Society for Environmental Toxicology and Chemistry Meeting held November 14-18 in Baltimore, MD. Paul Mayer made a presentation entitled "Effects of stream restoration on ground water nitrate at Minebank Run, an urban stream in the Chesapeake Bay watershed", which was co-authored by Elise Striz (GWERD), Peter Groffman (IES), Edward Doheny (USGS), and R. Shedlock. Steve Reynolds made a presentation entitled "Riparian buffer width, vegetative cover, and nitrate removal effectiveness: A review of current science and regulations", co-authored by Paul Mayer, Marshall McCutchen, and Tim Canfield (GWERD). A presentation by Edward Doheny (USGS) entitled "Pre-restoration geomorphic and sediment conditions of Minebank Run, Baltimore County, Maryland" was co-authored by Paul Mayer.
Robert Ford (GWERD) gave a platform presentation entitled "The Influence of Ground Water-Surface Water Interactions on Sediment Characteristics and Metal Accumulation at a Contaminated Site" at the 26th Annual Meeting (North America) of the Society of Environmental Toxicology and Chemistry on November 16 in Baltimore, MD. Co-authors for this presentation included Richard Wilkin and Frank Beck (GWERD), Kirk Scheckel (LRPCD), and Patrick Clark (TTSD). The presentation described results from a field study to determine the fate of arsenic, lead, and zinc following discharge of contaminated ground water into surface water downgradient from the Industri-Plex Superfund Site (Region 1).
Paul Mayer (GWERD) gave two invited talks to the Baltimore County Department of Environmental Protection Chesapeake Bay Program in November. The presentation entitled "Stream ecosystem restoration as a means of reducing nitrogen pollution entering Chesapeake Bay" was co-authored by Elise Striz (GWERD), Peter Groffman (IES), S. Kaushal, and Edward Doheny (USGS) and made to the Baltimore County Department of Environmental Protection and Resource Management in Towson, MD. His second presentation was entitled "Stream ecosystem restoration as a means of reducing nitrogen pollution entering Chesapeake Bay" and had the same co-authors. It was presented to the Chesapeake Bay Program in Annapolis, MD.
SPECIAL EMPHASIS PROGRAM NEWS
In recognition of National American Indian Heritage Month, the Special Emphasis Program celebrated the month by inviting Governor Bill Anoatubby of the Chickasaw Nation to speak to GWERD. He focused on the contributions the Chickasaw Nation has made to its people and Chickasaw Enterprises. The mission is to enhance the overall quality of life for the Chickasaw people. They are accomplishing this by providing wellness and nutrition centers, seniors programs, cultural centers, children's villages, tutoring and job search training, summer camps, housing, and other programs. A video, "An Enduring Nation", chronicled the nation's history from when its territory included Kentucky, Tennessee, Alabama, and Mississippi, prior to the nation's removal to Oklahoma.
