Lakes, rivers and inland marine waters are subject to pollution, much of which is attributed to wastewater plants and non-point source pollution from runoff. In cases where there is significant pollution from wastewater, failing septic systems, wildlife or livestock, the likelihood of pathogens in the water increases, which also increases the risk for disease among those who choose to swim or play in the water. However, inland beach water is not tested frequently due to costs. In addition, the time it takes to get results does not provide real-time data for swimmers. PHPID Fellow Jason Marion, a PhD student in the College of Public Health, is researching ways to address the time-to-result problem as well as the cost issue.
