MANSFIELD, PA— Four Mansfield University Chemistry students, along with two MU faculty members and one former faculty member, collected water samples and performed well water quality analysis in Tioga County, PA through a grant from the Tioga County Commissioner’s Office this summer.Students Emily Edwards, Martin Holdren, Joseph Mandeville and Megan Terrel, supervised and assisted by Professor Shaker Ramasamy, Assistant Professor Michele Conrad, both from the Department of Chemistry and Physics, and Paul Wendel, now on the faculty in the Department of Education at Otterbein University, OH, were involved in the project.
“With the rise in number of natural gas fracking sites in the Tioga County, it is important to monitor the well water quality over the course of the fracking process,” Conrad said.
The water quality study involved the Mansfield students collecting water samples from homeowners across the Tioga County and analyzing the water at no cost to the homeowners. A total of 82 well water samples were collected.
Water quality samples were collected at the same sites in previous years to monitor the pH, specific conductivity, barium and strontium. High levels of the two elements, barium and strontium, can be indicative of contamination from gas drilling.
This phase of the study incorporated substantially more analytes, as follows: ten cations (boron, barium, calcium, chromium, iron, potassium, magnesium, manganese, sodium and strontium), three anions (chloride, bromide, and sulfate), methane gas, pH, specific conductivity, and alkalinity. Samples were analyzed using Gas Chromatography/Mass Spectrometry (GC/MS), Ion Chromatography (IC), Inductively Coupled Plasma (ICP), and alkalinity titrations.
Out of the 82 sites sampled and tested, only two sites exceeded the recommended limit for strontium and methane and coincide with the same well water sites. The same two sites had higher barium concentrations with one exceeding the limit and the other close to the limit. The rest of the samples were below the maximum concentration limit for the key indicators (barium, strontium and methane) for gas drilling contamination.
The students’ methodology and results will be presented to the Council of Trustees on September 23 and at the annual Showcase of Student Scholarship in April 2016.
The workshop involved in a field course on the chemical and biological assessment of the Tioga River watershed and from the headwaters at County Bridge to the yellow-colored rocks of Island Park in Blossburg.
The workshop also included instruction on sources of pollution and the use of chemical tests and biological species identification to assess the water quality of the Tioga River as well as a demonstration of the complexities of groundwater characterization.
“The goal of the workshop was to provide teachers with tools to help lead their classes in understanding how to study the impact of human activity on surface water and groundwater using science,” Davis said.
MU Chemistry Professor Shaker Ramasamy shared research he is conducting on groundwater quality using the University’s Inductively Coupled Plasma (ICP) spectrometer with the participants.
Several MU students participated in leading the workshop by assisting the teacher-participants in performing chemistry experiments and in the identification of macroinvertebrates from the waterways. Read more

MANSFIELD, PA— Mansfield University science students created a mock crime scene in Spruce Hall recently and invited fellow students to participate in evaluating the crime scene, examining evidence and solving the crime.
Allyson Cornwell (Levittown, PA), Catherine Emerick (Tyrone, PA), Marty Holdren (Troy, PA), Meagan McCarthy (Bellefonte, PA), Bryan McCullough (Upper Darby, PA) and Hang Nguyen (Lewisburg, PA), supervised by Assistant Professor of Chemistry Michele Conrad, created the crime scene and assisted the student investigators Several also served as suspects.
Student investigators sketched the crime scene and then proceeded to the Forensics Crime Lab where hair was compared under microscopes and recorded and fingerprints were collected and studied under a magnifying glass. Characteristic patterns from the fingerprints, such as loops, whorls, and arches, were used to narrow down the suspects. Red stains were chemically tested for the presence of blood. Lastly, shoe prints were collected and compared.“All these factors culminated together to reveal the perpetrator of the crime, yet some evidence were unexpectedly misleading,” Conrad said. “This sample scenario gave students the opportunity to have fun solving a puzzle, to debunk common misconceptions from television shows and to gain a better appreciation for different forensic science techniques used in the field.”
MANSFIELD, PA—Seven Mansfield University Forensic Science students attended the 13th Annual Forensic Science Symposium at Cedar Crest College in Allentown, PA on March 28.
Catherine Emerick (Tyrone, PA), Chelsea Lovell (Canisteo, NY), Joseph Mandeville (Honesdale, PA), Bryan McCullough (Upper Darby, PA), Sabrina Shrawder (Danville, PA), Jessica Towey (Oxford, PA) and Harlie Wise (Mansfield, PA), accompanied by Assistant Professor of Chemistry Michele Conrad, attended the “Falcon Files: The Next Generation” Symposium.
The symposium consisted of seven one-hour presentations from specialists in the forensics field ranging from government to industry to cutting-edge research institutions. Topics that were covered included DNA analysis in combating human trafficking, cyberstalking, 3-D laser scanning in crime scene reconstruction, technological advances in lab-quality testing at crime scenes for gunshot residue and plants of abuse and forensic entomology.
“As students later reflected on what they learned from the symposium, they expressed that their interests were piqued as they related how their classwork is applied in the field,” Conrad said. “They were fascinated by the advances in technology that are being used at crime scenes, especially when it came to DNA analysis and materials characterization through vibrational spectroscopy and mass spectrometry. Through this experience, the students gained a better sense of their specific interests and had a fun time expanding their knowledge in a professional setting.”
MANSFIELD, PA— Mansfield University Chemistry students and faculty members Michele Conrad, Chemistry, and Michele Whitecraft, Education, took part in two National Chemistry Week (NCW) events during the week of October 20.
Chemistry Club members Elizabeth Clifford, Bryan McCullough, Marty Holdren, Joe Mandeville and Education student Ashley Baker, along with Conrad and Whitecraft, visited sixth grade science classes at Warren L. Miller Elementary School in Mansfield on October 20.
They lead discussions in various applications of science and powers of observation and inference and followed up with a forensic chemistry demonstration. Students were tasked to determine the identity of the writer of a mystery note. The students used a method called chromatography to separate dyes and pigments in black markers. The way the pigments and dyes separated allowed the students to make comparisons and identify the author of the note, whether a bully, a best friend or a crush.
“Students left the event excited to try the experiment at home,” Conrad said.
On October 23, Chemistry Club students Angie Kilyan, Joe Mandeville and Bryan McCullough, along with Assistant Professor Conrad, visited seventh grade classes at Corning-Painted Post Middle School in Painted Post.
Students collected their fingerprints and understood the different features to look for. They used these skills to identify a mystery superhero’s fingerprints.
“Students were excited to use their powers of observation to solve a mystery,” Conrad said.
The NCW events included several different demonstrations from scientists in the region. NCW is a community-based annual event that unites American Chemical Society local sections, businesses, schools and individuals in communicating the importance of chemistry to our quality of life.
Five area high school students took the qualifying exam to try and earn a spot on the U.S. National Chemistry Olympiad team on April 16 at Mansfield University.
