Dirty water effects on humans

This website is about how water becomes polluted. Pollutants runoff places and it goes into the rivers, streams, and groundwater. There are different levels of dangers of pollution. Our livers "detoxify" toxic substances in our bodies. Higher amounts effect our bodies more to a higher level of danger. Different people have different tolerances of the pollutants, but if they are toxic enough, there can be bad results.

What You Should Know about Water

This website is about what we forget about water. We use water for many things and forget the threats water may have. People drink bottled water and trust that there are no contaminants. They trust that it is safer than tap water. People try to treat their own water but forget about all of the treatment options today. With all of the information today, there is no reason that people should still be sick.

If a well is flooded, then people have to make sure that the water is safe. Floodwater carries bacteria, viruses, parasites, and chemicals. They can threaten health, clog up the wells, and sell bad, too. There are ways to make water safe to use like boiling, but not household water treatment devices. Chlorine helps disinfect, too. Too much chlorine will make it hard to remove from water systems. Laundry bleach also serves as a water dispenser cleaner.
