National News. In
April, Senior Research Scientist David
Feldman testified before the U.S. House of Representatives’
Subcommittee on Water Resources and Environment (Committee on
Transportation and Infrastructure). Feldman
offered testimony regarding proposals for a national Water
Resources Development Act 2002. His recommendations are based on the Southeast
Water Supply Roundtable, a broad stakeholder effort among southeastern
states that addressed water management and precursor to Tennessee’s Interbasin
Water Transfer Act of 2000. In addition, Feldman published “Tennessee’s Inter-basin Water Transfer Act: A
Changing Water Policy Agenda” in Water
Policy: The Journal of the World Water Council 3, 2001. Projects. Senior

and others are performing life-cycle assessments of various lead-based and
lead-free solders. Researchers hope the results of this study, funded by
the U.S. EPA and two trade associations—the IPC (an association
connecting electronics industries) and the Electronic Industries Alliance
(EIA)—will lead to environmentally sound choices for electronic
equipment. Currently, lead-based solders are used to attach components to
circuit boards; this study will examine the environmental impacts of these
and alternative solders in electronic products. Manufacturers helping to
fund the project through the IPC and EIA include Agilent Technologies,
Cookson Electronics, Delphi-Delco, Hewlett Packard, IBM, Intel,
International Sematech, Pitney Bowes, Rockwell-Collins, and Thomson
Consumer Electronics. Gary Davis,

Research Associate Jonathan Overly
have recently completed a report on single-use plates and bowls for Green
Seal, an independent product certifier. The researchers reviewed
environmental data for disposable plates and bowls, prepared a summary
background report, and developed a standard for such foodware. Companies
can review the standard and then submit products, along with production
information, to Green Seal for evaluation. By providing certification for
eligible products, Green Seal helps industry provide quality products
while reducing environmental impacts associated with their manufacture,
use, and disposal. Award. At
the campus honors banquet in April, UT Provost Loren
Crabtree presented a UT “Citation for Professional Promise” award
to graduate student Pedro Sanhueza. Sanhueza,
a WMREI-stipend recipient and Ph.D. candidate in Civil and Environmental Engineering, won the award based on his
grades and professional activities such as publishing and presenting
papers. Honors. At

“Citation for Professional Promise” award to graduate student Pedro
Sanhueza. Sanhueza, who
received a graduate research stipend from EERC affiliate the Waste
Management Research and Education Institute, is a Ph.D. candidate in Civil and Environmental Engineering. Sanhueza won the award based on his grades and professional
activities. Jack Geibig
received his master’s degree in Environmental Engineering this past
semester. Professors Bruce Robinson

coadvisors. After completing his coursework, Geibig
also passed his licensing examination and received his Tennessee

This edition focuses on a recent workshop where students gained experience
in field-laboratory logistics and research deep within South Africa’s
gold mines. Subterranean Science A field trip to
South Africa teaches students that a trip down into the darkness can be
the best way to appreciate the light of science. PULL QUOTE: By engaging undergraduate minority students in unique and multidisciplinary research, Pfiffner and Davis hope to recruit more students into the engineering, biological, and environmental sciences.By
Kris Christen “It
was a real adventure, and I loved the fact that we were getting away from
the lab and actually getting dirty for science,” says Jonesta
Nolan, a senior majoring in chemistry
at the University of Tennessee (UT). Nolan
was one of 13 undergraduate students (five Americans and eight South
Africans) who participated in a five-day field laboratory workshop held in
South Africa last December. The workshop, part of an ongoing U.S. National
Science Foundation (NSF) project to study life in the extreme environment
of South Africa’s gold mines, was organized and coordinated in part by
EERC affiliate the Waste Management
Research and Education Institute (WMREI) to provide undergraduate
minority students in the United States and “previously disadvantaged”
students in South Africa with experience in field laboratory logistics and
research. “What
we’re primarily looking for is whether or not organisms are down there,
what they are, what they do, and whether they have any special metabolic
processes that could be of interest in terms of bio-mining or enzymes for
biotechnological developments,” says Susan
Pfiffner, a research assistant professor in UT’s Department of Microbiology. One
idea is to isolate genetic material, either from environmental samples or
isolated bacteria, that is able to withstand high pHs and high
temperatures, says Kim Davis,
WMREI’s assistant director. “From there, we might genetically modify
other bacteria using these DNA strands or use enzymes from these bacteria
in microbiological processes.” In this way, various waste streams could
be eliminated from manufacturing and mining processes. Before
they entered the Beatrix gold mine near Bloemfontein, students donned
protective gear and weighted themselves down with an array of sampling
equipment. After hiking to their study site, the students collected
fissure water from flowing boreholes and gathered biofilms and rock, air,
and gas samples for further analysis. Students performed some tests on the
spot, checking for pH, temperature, dissolved oxygen, sulfide, iron,
chloride, and ammonia concentrations. “Spot-testing
helps you get a quick check on the geochemistry that’s going on in your
water sample, which gives you an idea of how to culture the organisms
later,” Pfiffner says. Once back in the lab, the students spent the rest
of their time conducting various microbial and molecular analyses for
bacteria in the samples, trying to get an idea of which organisms were
present and their abundance. After performing the analyses, they wrote lab
reports describing what they did, the materials and methods they used, and
their results. By engaging undergraduate minority students in such unique and multidisciplinary research, Pfiffner and Davis hope to recruit more students into the engineering, biological, and environmental sciences. The researchers are applying for another NSF grant to expand the workshop to a six- to eight-week summer session that offers course credit. They also hope to develop an undergraduate exchange program that would bring South African students to the United States. *** |
