Catalytic Converters
Contaminate Roadsides
Although catalytic converters reduce the carbon monoxide and hydrocarbons
produced from the combustion of a gasoline engine, they are also distributing
platinum group elements (PGEs) -- such as platinum, palladium, and rhodium
-- along roadways. Platinum is an allergen. The effects of exposure to
palladium and rhodium are unknown. As part of a two-year project, a University
team is investigating whether or not PGEs dispersed along roadways are
entering groundwater supplies or the food chain.
A team of University researchers led by Clive
R. Neal, associate professor
of civil engineering and geological sciences, has presented data indicating
that automotive catalytic converters distribute platinum-group elements
(PGEs) -- such as platinum, palladium, and rhodium -- as far as 50 meters
from the roadsides on which the vehicles travel. They are now in the
process of examining whether the PGEs dispersed by the devices could
enter groundwater supplies or the food chain.
The team -- Neal; Charles F. Kulpa, professor and chair of the Department of
Biological Sciences; and James C. Ely, research associate in the Department of
Civil Engineering and Geological Sciences -- has received a two-year grant from
the American Chemical Society to study the environmental impact of the PGEs.
They will be testing food crops for the uptake of the elements to determine the
extent of penetration. They will also be assessing the economic benefit of “mining” the
PGEs.

REU Program Focuses on Three Themes
Funded in part by the National Science Foundation and sponsored by the
Department of Civil Engineering and Geological Sciences, the eight-week
Research Experiences for Undergraduates (REU) program focused on three
areas for 2002 -- the development of water resources in Third World
countries such as Benin, Chile, Haiti, and Honduras; structural engineering
and analysis; and the development and operation of small community
mentoring centers.
At the end of the program students participated in a forum in which they
shared their experiences through 15-minute presentations. The keynote
speakers were Scott Tyler, director of the Hydrological Sciences Program
at the University of Nevada-Reno, and Michael Campana, director of the
Water Resources Program at the University of New Mexico. Tyler discussed
his work in the mountains of northern Chile, while Campana described
his efforts in Honduras.
The REU program provides undergraduates from across the United States
the opportunity to work with professional engineers, faculty, and other
students on collaborative, multidisciplinary teams. While many of the
students come from Notre Dame, a significant number are from other institutions.
Among the schools represented in the 2002 program were Princeton University,
the University of California-Los Angeles, Michigan Technological University,
the University of New Mexico, Taylor University, the University of Virginia,
and the University of Nevada-Reno.

Faculty
Member Called to Active Duty
Jeffrey W. Talley, an assistant professor in the College of Engineering,
was deployed to the Middle East in February 2003. “Although he
was unable to give us details while he was gone,” says Peter
C. Burns, Massman Chair of the Department of Civil Engineering and
Geological Sciences, “he checked in with us periodically, so
we knew he was okay. And, members of our staff sent care packages to
him to show our support of his efforts and concern for his safety.”
Talley, who returned home in July, is a lieutenant colonel in the United
States Army Corps of Engineers (USACE). He is chief of operations for
the 416th Engineer Command, which means he is responsible for all engineering
missions within the southwest Asia theater. His job during the Iraqi
conflict was to organize and control all of the theater Army engineering
missions throughout Kuwait and Iraq.
Typical design-and-build assignments for his troops included roads, airfields,
base camps, buildings, bridges, enemy prisoner of war camps, water and
wastewater treatment plants, and environmental baseline surveys of areas
impacted by the war. In addition, he and his troops were instrumental
in supporting humanitarian assistance to the Iraqi citizens by returning
water and electrical service to numerous Iraqi cities.
Because he specializes in the treatment of contaminated groundwater,
soils, and sediments, Talley was called on to assist in various environmental
assessment and remediation efforts of different environmental sites in
Kuwait and Iraq. Talley also provided environmental assistance to Task
Force Restore Iraqi Oil (RIO) at those oil fields destroyed by the former
regime. A faculty member since 2001, he has been been in the Army, serving
in active and reserve capacities, for 21 years.
The USACE is made up of approximately 35,000 civilians and 700 military
men and women. They are biologists, engineers, geologists, hydrologists,
natural resource managers, and scientists. The mission of the corps is
to provide “quality, responsive engineering services to the nation
including: planning, designing, building, and operating water resources
and other civil works projects; designing and managing the construction
of military facilities for the Army and Air Force; and providing design
and construction management support for other defense and federal agencies.”
The corps began in 1775 when the Continental Congress authorized the
first chief engineer to build fortifications at Bunker Hill. In 1802
the corps was stationed at West Point and constituted the nation’s
first military academy. With the founding of West Point in 1866, the
corps began a tradition of military and civil works that has continued
to the present. Today, the corps is organized into eight national divisions
and 41 districts throughout Asia and Europe.
It provides a wide variety of services ... from disaster relief and electrical
power generation and distribution to national water resource planning
and ship building management.
