Now it offically went from bad to worse.
NEW ORLEANS, Louisiana (CNN) -- Floodwater in New Orleans is contaminated with E. coli bacteria, a city official told CNN Tuesday.
The official in Mayor Ray Nagin's office declined to be identified.
The failures of the levee system after Hurricane Katrina's onslaught left about 80 percent of the city flooded with water up to 20 feet deep -- water that became a toxic mix of chemicals, garbage, corpses and human waste. (See video of restarted pumping station -- 2:14)
E. coli comes from human and animal waste and can be found in untreated sewage.
Drinking water contaminated with E. coli can lead to serious illness and death if not properly treated.
