Conor O’Brien, a student from Bangor High School in Maine, USA recently won first place in his category at the Maine State Science Fair for his research on the relationship between viscosity and flow rate in biosand filters at different temperatures. He was subsequently invited to submit a paper for the Stockholm Junior Water Prize discussing the differences in flowrate due to various viscosities of cold filters.
Conor O’Brien’s research stemmed from of a larger study conducted by Claire Tobin, who was a student researcher on a trip to Honduras in 2014 with Pure Water for the World. When Pure Water for the World decided to pilot biosand filters in rural schools, Claire returned from her trip and installed a biosand filter in her classroom, under the direction of her teacher Dr. Barbara Stewart, beginning a daily journey to a local impaired stream in Bangor, Maine.
