“The N.C. General Assembly authorized a $1.44 million plan to put 36 floating water circulators into the lake. It’s a hefty price tag, but is actually one of the drivers for the experiment. If it works, the savings could be huge as costs for implementing the EPA rules are estimated at $1 to $2 billion.Representatives from Medora Corporation, the company that will supply the mixers, say that the mixing process may confuse the algae, making them think they’re at different depths in the water. It could make them more vulnerable to viruses. The reps also say the mixers will work, claiming a 90 to 95 percent success rate in other lakes.”

In the news: A “stirring” solution to algae problems?
February 6th, 2014 by iisg_superadminIn the news: Federal judge’s ruling moves Chicago closer to clean water compliance
January 30th, 2014 by Irene Miles“Some good and long-awaited stormwater news quietly dropped the other day—a federal judge approved the Metropolitan Water Reclamation District of Greater Chicago’s (MWRD) Consent Decree, which is a binding agreement detailing very specific steps MWRD will take to move toward full compliance with the Clean Water Act and other federal guidelines on an equally specific timeline. There has been and will continue to be debate about whether the Consent Decree is strong enough, fast enough or green enough. But the reality is that it is now in place, and I’m excited that we can finally get to work on something, rather than sitting around waiting. I don’t read too many court rulings, but I found this one quite scannable.MWRD, of course, is responsible for wastewater and stormwater management throughout Cook County; on a daily basis it discharges treated effluent to area waterways, and that water must meet Clean Water Act standards. The same requirements hold true in storms, and that’s where most of the impetus for the Consent Decree lies: If there is more rain more quickly than MWRD’s infrastructure system can handle, the result is overflows of untreated wastewater and stormwater into those same waterways…resulting it MWRD being out of compliance with aspects of its Clean Water Act (and associated regulation) requirements. To be fair, many other metropolitan areas have the same problems, and as a result have their own Consent Decree in place. Several years ago MWRD, the U.S. Environmental Protection Agency and the Ill. Environmental Protection Agency began working out the requirements—finish the Tunnel and Reservoir Plan (TARP) by X, improve collection of ‘floatables’ in our waterways by Y, etc. When the draft Consent Decree was released for public comment, two separate coalitions of environmental organizations opined that the whole thing should be faster and greener. A federal judge was asked to determine if the requirements were reasonable, that went on for a bit, he decided they were, and now it’s what we have to work with, so let’s get to work.”
Research mission beginning today looks into microplastic pollution of the Great Lakes
August 8th, 2013 by Irene MilesThe first round of sampling revealed that the Lakes are home to between 1,500 and 1.7 million plastic particles per square mile, with Lake Erie housing the largest concentrations. Dr. Sherri “Sam” Mason of the State University of New York (SUNY) at Fredonia, Dr. Lorena Rios-Mendoza of University of Wisconsin, and Dr. Marcus Erikson of 5 Gyres Institute have determined that much of the plastic they found was actually microbeads, found in many brands of toothpaste and facial and body scrubs. These tiny pieces of plastic are less than a millimeter in diameter, much too small to be filtered out by wastewater treatment facilities before that water is released into nearby lakes and rivers.

Join the Invasive Crayfish Collaborative for an exciting webinar featuring Purdue University master`s student Izzy Paulsen. Izzy will share her mixed method study exploring how and why teachers use live crayfish and their interest in outreach. Her study draws from interview and survey data conducted in Great Lakes states.

Deadline extended! The IISG program, in cooperation with the @nationalparkservice at @indianadunesnps and @UrbanRivers in Chicago, is offering two internship opportunities to support conservation policy efforts. Sea Grant’s national Community Engaged Internship (CEI) program aims to broaden participation in coastal, ocean, Great Lakes, and marine sciences providing training and mentorship to the next generation of scientists, decision-makers, and citizens.
The program will do so by recruiting, retaining and engaging students in place-based research, extension, education, and/or communication that respects and integrates local ways of knowing.
Applications due April 21.

Meet IISG grad student scholar, Lena Azimi! Lena is a fourth-year Ph.D. student in the School of Civil and Construction Engineering at Purdue University, specializing in geomatics with a background in environmental engineering. During her master’s program, Lena encountered remote sensing technology, which provides a way to collect data from a distance, especially remote or hard-to-reach places. This experience led her to pursue a Ph.D. degree and dive deeper into remote sensing and tackle urgent environmental challenges.

Join us this Thursday for a seminar on the latest fish biology, ecology, and fisheries science happening in Lake Michigan.
Speaker will include:
-Anna Hill (Purdue) with an update on alewife diet and growth rates in Lake Michigan
-Charlie Roswell (INHS) with an update on Lake Michigan and Calumet River smallmouth bass movement
-Dan Makauska (IL DNR) with an update from the Illinois Department of Natural Resources
