The 7 Pillars of Health

Mary and I are reading a book entitled "The 7 Pillars of Health". The first pillars that we are studying is about water. Today is day 4 and we were doing pretty good about drinking enough water. But after reading todays assignment I am afraid to drink the water from the tap. Day 4 ended with this:

POINT TO PONDER: It’s best not to drink water straight from the faucet, because tap water may contain toxins, heavy metals, pesticides, residual personal care products, bacteria, and other microbes. One of the chemicals added to our tap water is fluoride. Generally, there are two types of fluoride: the type added to toothpaste (sodium fluoride) and the type added to drinking water (sodium silicofluoride). The latter is the most toxic of the two.

ACTION STEP: To check your city’s water supply, go the Web site www.ewg.org and click on the bar labeled “Tap Water Database: What’s in your water?” Search under the tab “local findings” and select your city’s name; it will generate a local water system report including any contaminants found in the water supply.
I could not find the tap water database at the above url. I found it here. Tap Water Database.
