Abstract: Landfills are notorious polluters of groundwater. The Eighty Acre
Landfill in Bemidji, Minnesota is part of the Minnesota Pollution Control
Agency’s Closed Landfill Program. Its four acres of fill hold an estimated
87,000 cubic yards of waste, primarily yard trimmings and boiler ash. A
previous magnetic survey of the site at twenty meter intervals showed that
magnetic field variations can delineate the landfill’s boundaries and also
revealed a magnetic anomaly in the landfill’s southwest corner. A later EM conductivity survey confirmed the existence of this anomaly. To better
define the anomaly, we conducted a magnetic gradient survey of the landfill
over a 100m X 110m grid, measuring at ten meter intervals. This higher
measurement density better defines the location and geometry of the anomaly
and provides information on the vertical gradient of the magnetic field. This
information will lead to a more accurate interpretation of the
anomaly’s source.

Abstract:The purpose of this experiment is to compare the effectiveness
of commercial water filters and their ability to filtrate out contaminants,
but exclude fluoride. Studies indicate safe concentrations of fluoride are
beneficial to teeth and bone health. The water filters will be commonly
available recognized brands. The water samples will be analyzed on an Ion
chromatograph to determine the concentrations of contaminants before and
after filtration. Other water types that will be analyzed include: tap water,
well water, city water, bottled water, spring water, and distilled water. Upon
comparison of these results it should be clear whether or not the commercial
water filters are effective or not.

Abstract: Three students formed a design company consisting of a Creative
Director, Production Manager and Budget Manager. The student design
company researched and designed a promotional campaign for a customer/
company’s product or service. The visual campaign includes the following: a
12 or 16 page full color catalog of products/services; a full color “quick starthow
to use” instructional brochure/flyer/booklet; a 4 to 6 panel full color
promotional brochure with die cut for promoting specific product or service’s
features through a specific distribution method; two 15” x 35” full color 1
sided promotional panels for the products/services that could be used in a
store or table display exhibit. Prototypes of each print component will be on
display in Bridgeman Gallery BN140. Students’ research documentation will
be summarized in a “Creative Brief” which includes the Project Summary/
Background, Audience Analysis, Goals/Objectives, Communication Strategy,
Job Specifications, Production Estimates and Budget with Timelines
for production.
