Regis science, technology, engineering, and mathematics [STEM] students conducted an experiment focusing on Ultraviolet (UV) light water disinfection in wake of the solar eclipse.

Specifically, the students tested the effectiveness of UV disinfection, both naturally [sunlight] and artificially.

“UV disinfection has gained popularity in recent years, especially after concerns about infectious diseases and the limitations of chemical disinfectants,” said Shannon Hogan, PhD, Assistant STEM Professor. “UV disinfection is considered cost-effective, especially when compared to the ongoing costs associated with chemical disinfectants, which can include handling, storage, and secondary pollution. It also helps the environment by reducing the use of chemical disinfectants, which can produce harmful by-products that may affect aquatic life and water quality.”

The results of the experiment show a clear decline in virus population with higher doses of UV light. This is called a dose response curve.

Virology is the study of viruses and virus-like agents, and infections. Students who study virology work in research institutions, healthcare facilities, and pharmaceutical companies. Their jobs can range from developing vaccines and antiviral drugs, to implementing public health policies.
