How Climate Change Is Making This River Run Backwards
By Henry Henderson
That's the number of gallons of contaminated Chicago River water that have flowed into Lake Michigan—source of drinking water and quality of life for millions of Americans—in the last decade. The river normally flows away from the lake, so what gives?
Blame climate change. And infrastructure not designed or built to deal with the changes brought the changing climate.
Violent storms dump an incredible volume of rain in very short periods of time. Even with massive additions to the region's stormwater system, it cannot keep up. When that system cannot handle intense rainfall over the area, sewers fill and dump into the River. When the Chicago River fills with all that stormwater, which is now contaminated with all kinds of nasty stuff after comingling with whatever was in the sewer lines, it swells. And after a while, well, gravity takes over. The river level rises above the lake level and water heads downhill. The Chicago River literally changes direction and flows out into Lake Michigan.
"If you are in the business I am in, you absolutely believe in climate change. We are seeing more intense, shorter duration rain events. We used to see several years in a row where we wouldn't have any reversals. But lately we are experiencing reversals at least once a year."
He would know. MWRD manages the stormwater infrastructure for Chicagoland, a massive swath of pipes, pits and tunnels underlaying nearly 900 square miles.
Which is all a long way around to saying, I can think of 33 billion other reasons for the Trump administration to rethink its rumored departure from the Paris climate accords. Chicago is hardly the only city which will face immense costs if this country does not seriously address climate change in the face of startling problems already visible today.

The EPA announced last week that it is issuing a preliminary regulatory determination for public comment to set an enforceable drinking water standard to two of the most common and well-studied PFAS, PFOA and PFOS.
This decision is based on three criteria:
- PFOA and PFOS have an adverse effect on public health
- PFOA and PFOS occur in drinking water often enough and at levels of public health concern;
- regulation of PFOA and PFOS is a meaningful opportunity for reducing the health risk to those served by public water systems.

Driving an electric-powered vehicle (EV) rather than one reliant on fossil fuels is a key way to tackle climate change and improve air quality — but it does leave the old batteries behind as a nasty residue.
