The current approach to wastewater treatment manages nitrogen, phosphorus, and organic carbon as pollutants removed through energy- and chemical-intensive treatment processes. Although this is effective at protecting public and environmental health, this method consumes 3% of U.S. electricity and still results in excess nutrients reaching aquatic environments.
More broadly, conventional strategies for wastewater management rely on technologies that are prohibitively expensive for developing communities in which 2.4 billion people lack access to improved sanitation. This presentation will provide a framework to identify and prioritize opportunities for innovation to advance the UN’s Sustainable Development Goals for sustainable cities, responsible consumption/production, and universal access to sanitation by 2030, with attention to emerging technologies that leverage human bodily excreta as a renewable source of nutrients (for agriculture) and energy.
About Jeremy Guest Dr. Jeremy Guest is an Assistant Professor in the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign (UIUC). His research focuses on the development of technologies for sustainable water and sanitation, with a focus on resource recovery from bodily excreta in technologically advanced and developing communities.

Since early 2010, Freshwater Society and the University of Minnesota College of Biological Sciences have co-hosted a FREE stimulating lecture series on water and the environment. The lectures, known as the Moos Family Speaker Series on Water Resources, honor the late Malcolm Moos, president of the university from 1967 to 1974. The series brings together influential experts on a broad array of topics and pairs a nationally-known speaker with a panel of regional experts. They present the latest research on timely and important issues through an accessible -- and often entertaining -- presentation.

|Title: “The Arctic Meltdown and Extreme Weather: How Are They Connected?”|
May 9, 2018
Does it seem as though the weather is a little "different" lately? Minnesota's rainfall amounts and intensity have changed and that has implications for our storm sewers and floodplains. Dr. Francis explained new research that links increasing extreme weather events with the rapidly melting Arctic. Evidence suggests weather patterns are becoming more persistent, which can lead to extremes such as droughts, cold spells, heat waves, snowy winters, and flood events.

|Title: “The Lake Effect: Protecting water through innovative collaboration”|
November 14, 2017
The Yahara watershed, like many others, is threatened by excessive phosphorus from sources as such as agricultural runoff, urban stormwater, and wastewater treatment plant discharges. The elevated phosphorus levels are a threat to water quality and aquatic life throughout the area. Yahara WINS began in 2012 as a four-year pilot project to reduce phosphorus loads and meet more stringent water quality standards established by the Wisconsin Department of Natural Resources. This groundbreaking program employs watershed adaptive management, a strategy in which all sources of phosphorus pollution in an area work together to meet water quality goals. This strategy is more effective and less expensive than the sources working separately on individual solutions.

|Title: “The Death and Life of the Great Lakes”|
April 15 and May 24, 2017
The Great Lakes provide the largest source of fresh surface water in the world as well as food, work, and weekend fun for tens of millions of people. Yet they are under threat as never before, and it’s only getting worse. In a time when the federal government proposes eliminating funding for cleaning and protecting the Great Lakes, two-time Pulitzer Prize finalist Dan Egan has written an urgent and powerful wake-up call, and makes a clear and convincing case for how our problems can be fixed. In the grand tradition of Rachel Carson’s Silent Spring, Egan’s The Death and Life of the Great Lakes is a master reporter’s landmark work that takes readers through the science, politics, history, and economics of the lakes, revealing an ecological catastrophe happening right before our eyes.

|Title: “Designing for Our Future – Sustainable|
Infrastructure and the Triple Bottom Line”
November 15, 2016
Our urban communities are facing ever increasing pressure to find elegant solutions to the grand challenges we face – shifting economies, changing demographics, and impacts to our landscapes and natural systems – compounded by the added stress of a changing climate. Join Ms. Attarian to hear about designing for our future by incorporating sustainable design into every street corner, and what that means to our community’s sense of place. She will also share stories and lessons learned from her own work with the cities of Chicago and Detroit.

|Title: “Evolution to Cleaner Water and Greener Water Companies”|
April 13, 2016
George Hawkins, CEO and General Manager of the DC Water and Sewer Authority, discussed how our thinking about environmental protection has evolved and the implications for cities. DC Water operates one of the largest wastewater treatment plant in the world and has launched an ambitious and innovative program to improve aging infrastructure in the Washington DC region to comply with strict environmental requirements. A recently completed digester system is generating 10MW of electricity - enough for about 7,500 homes.

|Title: “Protecting Surface Waters in Agricultural Watersheds’”|
November 3 and 4, 2015
Bill Stowe, CEO and General Manager of Des Moines Water Works [Des Moines, Iowa], spoke on the central Iowa utility’s mission to provide safe, affordable and abundant drinking water to 500,000 customers and the challenges faced in an agricultural watershed. Iowa’s EPA-mandated Nutrient Reduction Strategy states that 92% of total nitrogen sources are currently not regulated; however, the strategy to reduce nutrient pollutants by 45% has no timelines, commitments to measurements and relies on voluntarism. Iowa’s capital city’s drinking water utility recently filed a federal complaint against three upstream counties in their capacities as trustees of 10 drainage districts, for the discharge of nitrate pollutants into the Raccoon River (the utility’s source water), and failure to obtain a National Pollutant Discharge Elimination System (NPDES) permit in violation of the Clean Water Act.

|Title: “The Outsized Role of Earth’s Largest Lakes’”|
April 30, 2015
Roughly two thirds of the planet’s available surface freshwater is contained in just twenty lakes. Scattered around the globe, and diverse in almost every measurable respect, these immense “dimples” in Earth’s surface have shaped human society and history. Their value continues to grow as freshwater scarcity increases. This talk will explore Earth’s largest lakes, some of which are in our backyard, from the standpoints of hydrology, biogeochemistry, biodiversity, and geopolitics, using these approaches ultimately to ask what role these twenty places play in our lives.

|Title: “Sediment, science, and stakeholders – clearing the muddy waters of the Minnesota River’”|
January 20, 2015
The Minnesota River cuts a vast valley through southern Minnesota before merging with the Mississippi River. It crosses fertile lands– and transports volumes of sediment. The geologic history of the Minnesota River makes it a large source of sediment, and land use with climate changes have greatly increased this supply.
