ABC News chief health and medical editor Dr. Richard Besser collected floodwater and drinking water in some of the areas hit hardest by Sandy and had them tested at The Ambient Group lab. The floodwater collected in Lower Manhattan tested positive for gasoline and two types of bacteria found in sewage: E. coli and coliform.
“Very dangerous,” Besser said. “Make sure you wear protective gear if you are coming into contact with flood water.” Looking at the testing containers filled with Manhattan floodwater, Besser explained that the yellow glow indicated that coliform bacteria was present at high levels. The purple fluorescence tells us that there are sky-high levels of E. coli from sewage contamination.
