UGA Graduate Student to Use EPA Fellowship to Study Fecal Pathogens

Mr. Adelumola Oladeinde, a second-year doctoral student in the University of Georgia College of Public Health, has been awarded a Science to Achieve Results, or STAR, fellowship from the U.S. Environmental Protection Agency.

He will use the two-year, $84,000 award to study how the organic matter present in manure aids the growth of fecal pathogens and extends their presence in the environment, particularly in the bodies of water used for drinking and recreational use.

According to the EPA, 60 percent of the rivers, lakes and streams in the U.S. are considered “impaired,” which means they do not meet water-quality standards and are too polluted for swimming or other recreational activities, explained Mr. Oladeinde, who is studying environmental health science.

“The main reason for this is that these waters contain pathogen levels well above the EPA limit,” he said. “And when you track back the probable source of these pathogens, it almost always leads to agriculture.

“Cow manure is rich in organic matter and nutrients, such as nitrogen and phosphorus, that pathogens can potentially use to survive for some time in the environment. And sunlight, while it has the ability to kill bacteria, can also break down nutrients into photoproducts that can stimulate bacteria growth.”

Most studies on the fate of pathogens focus on their die-off in the environment without taking into account their ability for regrowth under favorable conditions. With his EPA-funded project, Mr. Oladeinde hopes to fill in this gap of knowledge.

“If we can measure particular nutrients to predict the growth of various pathogens in the environment, we will not only be able to better predict the risks of infection, but can develop strategies that allow us to mitigate and adapt to those risks,” he said.
