Drinking polluted water can cause conditions such as vomiting or diarrhea, sick to the stomach and if ingested for long periods of time cancer and reproductive problems.

Ways to protect yourself are:
1. If you have well water get it tested.
2.Filter water if needed.
3. Recycle batteries and paint.

The water production plants in the United States do a good job cleaning water.   Most of it in the U.S. is safe to drink.
