Rapid Identification of Bacteria Sources that Lead to Lake SuperiorBeach Advisories

This project builds on previous Sea Grant research designed to  pinpoint the sources of bacteria that contribute to beaches being  "closed" (posted with "water contact not recommended" signs).  Researchers will use two new genetic techniques (robotic-assisted   gene  probing and quantitative PCR) to more rapidly identify whether the  sources of fecal bacteria at several Lake Superior beaches come from  birds or humans. If the bacteria are from humans, the health risks   may  be more serious than if the sources are from waterfowl.     They plan to take sand, sediment, and water samples at several Duluth  beaches to see if bacteria vary daily in response to natural and   human  activities, including outflow from the sanitary district. They will  also test drainage pipes and stream outlets entering the lake near   the  beach sites.    Their findings will help agencies post more accurate water contact  advisories, verify contamination sources so they can be removed, and  to detect unsuspected sources of fecal contaminants. The techniques  developed will have widespread applicability to other coastal regions  and areas of the Great Lakes.    (beach closure); (beach closures); (beach closings); (beach closing)
