Caitie Nigrelli, an environmental social scientist working for IISG and the U.S. EPA, has been featured in a Christian Science Monitor article about her involvement in the cleanup of the Grand Calumet River in Northwest Indiana.

The reason behind the article? “Industry and environmental interests are often opposed. But in Indiana, a river cleanup requiring both sides to negotiate with each other offers an example for conservation partnerships everywhere.”
