The dollars and cents of sediment remediation

February 11th, 2015 by
We talk a lot about the environmental benefits of sediment remediation. These are hard to miss—a trip to the river or harbor is often all it takes to confirm that the aquatic habitat is on the mend. The role of cleanup projects on local economies can be harder to pin down, but the impacts are just as striking. Brandon Steppan, IISG’s new communications intern, has the story. 
 
I’ve lived in the city all my life. With the exception of a few parks and forest preserves, I never really saw environmental health as being all that connected to the welfare of my community. The only rivers that ever made the news were the Chicago River on St. Patrick’s Day and the Des Plaines River whenever it flooded—especially if that meant Gene and Jude’s, an iconic hot dog stand in River Grove and arguably the best place to get a Chicago-style hot dog, would have to shut down for repairs.
 
What I’ve learned about other Great Lakes communities in the short time I’ve been with IISG has already made me reevaluate just how valuable a healthy river can be—not just in terms of environmental integrity, but in dollars and cents. Results of economic studies of Great Lakes Areas of Concern (AOCs) have listed the values of what a clean waterbody would be for those communities, with numbers ranging from $6 million for one small neighborhood to $19 billion for all 31 original AOCs in the U.S. To get these numbers, economists and social scientists looked at money brought in from tourism, real estate values, and residents’ willingness to pay for a cleaner waterway. 

One of the more remarkable returns came from a 2004 examination of the Waukegan Harbor AOC in Illinois. An analysis of housing data and resident perceptions determined that proximity to the PCB-ridden harbor substantially drove down property values. When surveyed, Waukegan homeowners revealed they would be willing to pay more for their property if it meant full cleanup of the harbor—a collective value of $436 million, much more than the projected cost for remediation.
 
My initial reaction to these reports was a mixture of confusion and surprise. But as I took into account the number of people in each area and how they rely on their local rivers not just for livelihood but for quality of life, the numbers no longer seemed all that surprising. The hazards of a toxic river bed aren’t always obvious, and unfortunately, neither are the benefits of remediation. Having these numbers available helps create a conversation where those benefits are no longer vaguely environmental, but economically tangible.
