DescriptionThere are fears of a looming health crisis due to toxic water flooding the streets of Houston. That water flooding into homes isn't just rain. It's mixed with sewage and chemicals, bacteria and potentially disease. There has been shocking video of many people walking through the filthy floodwater, including a toddler. Bacteria isn't the only danger lurking in the water. Creatures like alligators also pose a threat. One woman shot video of two gators swimming in her flooded backyard.
