2012 Berea College Research Symposium

The Berea Undergraduate Research Symposium (BURS), held each fall the same weekend that the Berea College Trustees visit campus, is an opportunity for the students and faculty to share research work with each other as well as these important campus visitors. This has been organized by the science programs in the past but participation is open to all members of the college community. In recent years we have structured the symposium with both talks and poster presentations as well as a plenary session.
The program for Fall 2012 will be held on Friday, October 5th. The 2012 BURS will start in the afternoon with student oral presentations, continue with student poster presentations, and and with a plenary talk by Paul Brown, a former scientist at the National Institutes of Health.
We generally start at 2:30 PM with two simultaneous oral presentation sessions (15 minutes each) in rooms 101 and 106 of the Science Building. The sessions are grouped by theme as much as possible. The poster session starts at 3:30 and is held in the lobby of the science building with posters from various fields (previous posters from chemistry, biology, physics, psychology, sociology, education, African American Studies, economics, industrial arts, computer science, physical education & health, and mathematics). All students who pursued substantial research projects over the previous year are encouraged to present their research.
We have been hosting the BURS since 2001 and have records of participants going back to 2007 online (see links to the left).
Students and faculty interested in attending or participating in the 2019 BURS should either contact Jay Baltisberger or Anes Kovacevic of the chemistry program. Alternatively a student may elect to register online via the link on the Chemistry department web server.

Characterization of disinfection byproduct (DBP) formation potential within the Ashokan watershed: Effects of filtered and unfiltered chlorinated water samples

Ivan Titaley
Mentor: Megan Ferguson
Performed at State University of New York at New Paltz
Chlorination of water containing dissolved organic carbon (DOC) can result in the formation of harmful halogenated compounds known as disinfection byproducts (DBP). The formation potential of DBP was characterized in the Ashokan Watershed. The issue of DBP is of particular interest due to the fact that the city of New York does not filter its drinking water. Since parts of the Ashokan Reservoir watershed have high turbidity, these sediments could affect the fate of DOC. Filtered, unfiltered-settled and unfiltered-shaken sample treatments were used to model filtered, settled down, and turbid water conditions in the Ashokan reservoir, respectively. Samples were taken at sites along the Warner, Stony Clove, and Esopus creeks as well as at the beginning of the aqueduct leaving the reservoir. Water samples were collected and chlorinated to model actual water supply. The chlorinated water was analyzed with UV-Visible spectroscopy to determine the extent of total halogenations and the amount of unused chlorine. Aliquots of the samples were further extracted with pentane and methyl tert-butyl ether (MTBE) and run on GC/MS to quantify chloroform (CHCl3) and haloacetic acids (HAA), respectively. The majority of both chloroform and HAA results indicated less than limit of quantization for the chlorinated water samples—regardless of whether the sample was filtered, unfiltered-settled or unfiltered-shaken. Of those that did have significant DBP signals, unfiltered-settled water samples tend to have higher DBP formation compared to filtered water samples, albeit still lower than Environmental Protection Agency (EPA)’s 0.08 mg/L maximum contaminant level goal (MCLG). The results are as hypothesized because there are more DOC concentrations in the unfiltered water samples, which could lead to high DBP potential formations.
