WITH STEVEN JOHNSON
CLEAN
WEDNESDAY, OCTOBER 15 @ 7:00PM & 12:00AM
Dirty water has killed more humans than all the wars of history combined, but in the last 150 years, a series of radical ideas, extraordinary innovations and unsung heroes have changed our world. Steven Johnson plunges into a sewer to understand what made a maverick engineer decide to lift the city of Chicago with jackscrews in order to build America’s first sewer system. He talks about John Leal, who deliberately “poisoned” the water supply of 200,000 people when, without authorization, he added chlorine, considered lethal in 1908, into Jersey City’s water and made it safe to drink.
