About 40% of the continental U-S drains into the Mississippi River. It sends water – and pollution – from across the country into the Gulf of Mexico. A new study shows just who the worst offenders are. Gabriel Spitzer has the story:
All the pollution creates a dead zone in the Gulf nearly the size of New Jersey.
Nitrogen and Phosphorus pour in and fertilize big algae blooms.
When that stuff decays, it sucks oxygen out of the water, and makes it impossible for most fish to live there.
US Geological Survey researchers say most of the problem comes from farm runoff, but the single biggest source is sewage from Chicago.
Albert Ettinger with the Environmental and Law Policy Center says Chicago water managers have to catch up with their neighbors.
“They’re gonna have to look at treatment systems which take nitrogen out of the water, and bring phosphorus down to one milligram per liter. It’s done in Milwaukee, it’s done in Cleveland, it’s done in Detroit.”
Chicago’s Metropolitan Water Reclamation District say they haven’t had a chance to look closely at the study yet, so they don’t want to comment on it.
But they don’t like being singled out.
