Here is the risk of lead being present in tap water for the Santa Barbara region. 1 is low risk, 10 is high risk. Link for this map is in the comments, where you can zoom on any neighborhood in the U.S.

Here's a nice graphic explaining how lead gets in your tap water. It happens right at your house, so the only way to know if you have lead in your tap water is to test it yourself. If you do, then you will need to filter it out.

Lead contamination in drinking water is caused both by actual lead pipes or by lead in the solder in the fittings. Only by testing for lead at the POS (point of service) will you know if you have lead contamination. If you live in an old house, beware!
Now, Seattle is under scrutiny:

"No amount of lead is safe."

To be on the safe side, have your child bring one or two re-usable water bottles to school. Distilled water is the safest water to drink, and the best re-usable bottles are glass (with a cloth or foam protector).

A new poll says 1/2 the population distrusts their tap water, and 1/3 buy bottled water.
