Professor helps keep beaches open
A new bacterial forecasting system developed by Greg Olyphant, associate professor of geological sciences, has made it possible for cities to accurately predict potentially hazardous bacteria levels along Lake Michigan. The system may potentially eliminate unnecessary beach closings, which have plagued lakefront cities such as Chicago and Milwaukee. Olyphant's system uses weather characteristics such as recent rainfall, wind, lake levels, air and water temperature and sunshine to estimate E-coli levels in the water as well as on the beach. What makes the model so valuable is its timeliness, Olyphant said. The new computerized approach can forecast E-coli levels within just three hours.
