EWG -- the "Environmental Work Group," a non-profit consumer advocacy group -- has ranked the water quality of the nation's 100 largest cities.

Here's their take on the top 10 water systems in America:

1. Arlington

3. Fort Worth

4. Charleston, S.C.

5. Boston

6. Honolulu

7. Austin

8. Fairfax County, Va.

9. St. Louis

10. Minneapolis

If you're wondering how San Antonio (SAWS) fared, we came in 29th. The report found some chemicals -- many which are unregulated and perfectly legal in the water consumed by all San Antonians.
