Transcript for Concerns raised about dangers of Harvey floodwaters
water, estimated more than 10 trillion gallons of rain have already fallen on Texas. Trillions more expected before it finally ends. We have the details from Dickinson, Texas, with Eva pilgrim. Reporter: So much more rain overnight. Some of the roads we've been taking since we arrived are no longer passable. Very hard for us to get out. I just want to show you where we are at this gas station. You can see there's water all around. There is a car in the water. Just a short distance away and those are adding to some of the concerns about what is in the water here. Think about what you keep in your garage, paint or things that you use to work on your car, those things are now covered by water because a lot of these areas, the water covers the entire first floor of these homes. Not to mention the wildfire that is in the water talking snakes and alligators and mounds of ants. I want you to see what they look like. Even if you're paddling by it, don't stick your paddleboard in those ants they can be very dangerous if you touch them. Interesting thing that's happening. Some of these beer companies are switching from making beer to bottling water because this area is in such desperate need of having clean drinking water. So much water around us but none of this water is something that people can drink, George. No way. Okay, Eva, thanks very much.
