bowl of toxic soup

So some experts are concerned now that New Orleans will be turned into a giant cesspool of sewage from burst lines, toxic chemicals from the industrial plants that line the Mississippi, and human remains from all the cemeteries. The fear is that the system of levees designed to protect the city from the river flooding will essentially trap all the water in the city turning it into Lake New Orleans--watery death and disaster. I really really really hope this does not happen.
