What are we going back to?

I'm beginning to think the mayor's plan to start allowing residents back into Orleans Parish next week is a poorly thought out PR move. I'm just as anxious as anyone to go home, but I'd prefer not to feel obligated to return until at least some of this gets sorted out.
Hurricane Katrina is rapidly becoming the worst environmental calamity in U.S. history, with oil spills rivaling the Exxon Valdez, hundreds of toxic sites still uncontrolled, and waterborne poisons soaking 160,000 homes.

New Orleans' flooded neighborhoods are awash with dangerous levels of bacteria and lead, and with lower but still potentially harmful amounts of mercury, pesticides and other chemicals. Much will wind up in the soil as the water drains, or in Lake Pontchartrain, hammering its already battered ecosystem.
......
At the EPA's request, the Army Corps of Engineers put out floating barriers to try to stop some oil and gasoline before it enters the lake. But they won't stop the two most immediate threats in the water, high levels of bacteria and lead.

One site sampled Sept. 3, an Interstate 10 interchange north of the French Quarter, had lead 56 times higher than the amount that would be allowed in drinking water. Other samples taken days later across a much wider area were also high, but not near that mark.
......
Tests also show that toxic substances in the floodwater will enter the coastal food chain.

Several water samples had mercury, a powerful nerve poison, above the amount allowed in saltwater environments in order to protect the long-term health of people eating fish or shellfish.
......
The air, too, is a source of danger in New Orleans. An EPA airplane equipped with electronic sensors to spot air pollution detected a plume of chloroacetic acid, an industrial agent and defoliant that poses extreme toxic risks when inhaled.
......
Another concern, he said, is that long-lasting pollutants will remain in higher concentrations and higher toxicity when the water dries up. "The question will be how much will get into people by the three routes, respiratory, gastrointestinal and dermal or skin."
By opening the city, the Mayor is basically obligating renters to return to an unsafe environment or risk having their slumlords clear out and dispose of their belongings left behind during evacuation. Don't think they won't do it? You don't know New Orleans slumlords.
