Steve Mauro’s research into the impacts of pharmaceutical and personal care products (PPCPs) on bacterial communities may have started as a small side project, but it has become so much more. The Gannon University dean gained national attention in 2011 when he and his research team discovered that small concentrations of fluoxetine are killing E. coli in the nearshore waters of Lake Erie. Today, Mauro continues to investigate exactly where and how fluoxetine and other pharmaceutical chemicals, both individually and combined, are changing the microbes that keep aquatic ecosystems healthy. And it is this work that brought IISG to his office bright and early on a June morning.
 
In this issue of UpClose, Mauro goes beyond his work on PPCPs to talk about the importance public outreach and about new efforts that are making it easier for forecasters and beach managers to predict when E. coli levels may make a trip to the beach more trouble than its worth.

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.Watch the 3-part video series at the link in bio.(Photo credit: Liz Spitzer, Illinois State Geological Survey, Coastal Research Group)
