“Gray infrastructure is the system of pipes and ditches that channel storm water. Green infrastructure is the harnessing of the natural processes of trees and other vegetation — so-called ecosystem services — to carry out the functions of the built systems. Green infrastructure often intercepts the water before it can run into streets and become polluted and stores the water for gradual release through percolation or evapotranspiration. Trees also clean dirty water through natural filtering functions.Advocates say green infrastructure isn’t just about being green — it makes financial sense, as well. Its cost-effectiveness depends on how benefits are assigned and valued, and over how long a time scale, but green has been shown to be cheaper than gray.”

August 16th, 2012 by Irene Miles“That will allow the federal government to build a new barrier there to keep sea lampreys from breeding in the river. Managers of the fishery expect that will bring the lamprey problem under control in Lake Michigan.”
Sea Grant staff take to the sea for research

“The Great Lakes National Program Office (GLNPO) of the U.S. Environmental Protection Agency (USEPA) is responsible for monitoring the offshore water quality of the Great Lakes to evaluate water quality over time and identify any emerging water quality problems. Comprehensive water quality surveys are conducted in all five Great Lakes in both the spring, when the water is cold and well mixed, and in the summer, when the lakes are biologically active. The R/V Lake Guardian is currently being used to conduct the summer water quality survey.”

August 7th, 2012 by Irene MilesIn the news: New Illinois law helps prevent spread of AIS
August 2nd, 2012 by Irene MilesAs an amendment to the Boater Registration and Safety Act signed into law by Illinois Governor Pat Quinn, aquatic plants and animals would need to be removed from seaplanes and watercraft before moving between bodies of water. The requirement is an important step in preventing the spread of aquatic invasive species throughout the state of Illinois, as well as between states and bodies of water where these vehicles might travel.
Growing water needs and shifting availability require new solutions
June 26th, 2012 by Irene Miles“Water is reused in two main ways: non-potable reuse, in which treated wastewater is used for agriculture and landscape irrigation, industrial applications (such as cooling processes), toilet flushing and fire protection; and indirect reuse of wastewater to recharge ground water supplies, allowing treated wastewater to percolate down to aquifers and replenish water sources. Overall, non-potable and indirect reuse of water in the U.S. is growing rapidly, with more than 2 billion gallons reused per day, and volume increases at an estimated 15 percent annually.”
Local water travels a long, long way
June 25th, 2012 by Irene MilesWatersheds are areas where water comes together and drains to a common place. In addition to the streams and rivers and creeks that we can see, though, watersheds encompass a huge range of pathways for water, and your nearby water supply might be part of a very large system that spans multiple states.
“Of course, obtaining sustainable development in town isn’t enough, in and of itself, to guarantee high quality, fishable and swimmable rivers and streams. Industry plays a part; utilities and waste water treatment plants play a part; sensitive farming, ranching, and/or timbering play a part, all in different proportions depending upon the particular watershed in question.”
IISG and the Windy City Earth Force team up to empower Chicago students
June 15th, 2012 by Irene MilesIISG education team members Robin Goettel and Terri Hallesy partnered with Angie Viands of the Field Museum’s Earth Force Program, along with students and teachers within the Calumet community to raise awareness about properly disposing of pharmaceuticals and personal care products (PPCPs).
Windy City Earth Force is part of the museum’s Calumet Environmental Education Program (CEEP). Earth Force is a program that engages 7th and 8th grade students in action projects to address environmental issues in their community.
Ms. Pettis’ 7th grade students’ goal was to find out about potential health concerns for humans and animals caused by PPCPs and to find out what health concerns may lurk within our water supply.
– Letters to stakeholders, including businesses, legislators, and environmental organizations (including National Resources Defense Council and Illinois Department of Agriculture) about contaminates in the waterways and the importance of water quality standard improvements.
– Fliers to distribute to the public, as well as family and friends about the issue of contaminants and how they can make a difference in their community.
– Posters in local businesses and churches with the message “Stop Pollution in our Water: be green, stop pollution, and save our Earth.”
– School-wide surveys to determine the pollution tolerance index rating for various aquatic species.
– E-mail messages to editors at Southtown Star newspaper and Treehugger.com requesting them to publish their classroom project.
In addition, they developed a flier about how to help dispose of medications including the location of the nearest police station collection box.

In the news: Testing Lake Michigan water to maintain a safe shoreline
May 31st, 2012 by Irene Miles“Chicago’s new elaborate system of buoys and statistical models will monitor 16 of the city’s 24 beaches, and Park District officials are seeking grant money from the U.S. Environmental Protection Agency to expand the system to cover all beaches by next summer.The model will predict the levels of harmful bacteria at each beach using data on the location of sources of contamination, like colonies of sea gulls or sewer outlets; the motion of waves that can disturb bacteria growing in the sand; lake-current speeds; water temperature; and sunlight.”
