To Clean After Hurricane Katrina

In a new study analyzing the environmental effects of Hurricane Katrina, the scientists state that household levels of mold and bacterial endotoxins in three single-family homes were so considerable that they equaled or surpassed those in waste- water therapy plants, cotton mills, and agricultural environments.

Scientists at Columbia University's Mailman School of Public Health, report that following Hurricane Katrina, a number of New Orleans homes remained underwater for weeks, promoting heavy mold growth. The scientists selected three New Orleans houses for this mold study. These three homes were selected for the study based on their levels of flood water, whether they previously were structurally sound, and if they were located in an area likely to be rebuilt. The study was looking at the extent to which these homes experienced significant and prolonged exposure to flood waters and effort to satisfactorily clean for reconstruction. These houses were inspected for roof leakage, standing water and the extent of mold throughout their interiors, as well as heating ventilation and air conditioning.

"From our data, it is clear that levels of mold were so high that we strongly recommend that those entering, cleaning, and repairing flood-damaged homes wear respirators that are more protective than plain dust masks," said Ginger Chew, ScD, assistant professor of environmental health sciences at Columbia's Mailman School of Public Health. "While our assessments of the data are based on a small demonstration project, the results give a clear picture of what is acceptable in flood clean-up procedures".

"Our goal was to make recommendations for the safe removal of flood-damaged articles, safe re-entry into homes, and safe levels of worker protection," said Jonathan Wilson, deputy director of the National Center for Healthy Housing.

Scientists hope that they are findings not only would inform those involved in current clean-up activities in New Orleans and other environments, but will also benefit those responding to any future disasters that may occur.
