Persistent Pollution: Researchers Investigate the key to E. coli Bacteria Survival in Lake Michigan Beach Sand and Water
Sea Grant-funded researchers Sandra McLellan and Gyaneshwar Prasad, both with the University of Wisconsin-Milwaukee, are building on previous research to find ways to decomplicate beach managers’ lives by determining what factors could limit long-term survival of E. coli on beaches. They are also in the process of developing a scorecard for the potential of long-term E. coli reservoirs for each of the six Lake Michigan beaches they are studying.
