Pathogenic bacteria assessment of sachet water sold at the streets of Ghana

In collaboration with; Evans Afriyie-Gyawu (Georgia Southern University)

“Sachet water” is the main drinking water source commercially available in Ghana. This summer, MPH second year student Christina Beslin conducted a study at 6 locations in Ghana to assess the water quality of these water bags. These samples will further be analyzed to investigate the pathogens in these waters as well as the sources of bacterial pollution. Quantitative polymerase chain reaction method will be used to quantify these pathogens and identify these sources.

Occurrence of waterborne pathogens and microbial risk assessment of contacting river waters in Haiti

Surface waters, particularly rivers are the main source of water for people living in the remote areas of Haiti. This summer, doctoral candidate Val Reagon has conducted a study at a rural village in Haiti to assess the microbial quality of the river water. This river has been the only source for people to wash their dishes, bathing, or preparing food. These samples will further be analyzed to investigate the microbial diversity in these waters as well as pathogen quantity and the sources of pollution.

As a part of this collaboration, the group is working on developing and demonstrating how new genomics tools such as microbial source tracking methodologies can be used to characterize and quantify human fecal pollution in water in order to advance understanding of the impacts of wastewater and sanitation on human health.
