6. As long as your municipal water supply is free of lead, you don't need to worry about
6. lead in your tap water.

A. True B. False

Answer: B. Though your municipal water supply may be free of lead, it can enter your
tap water through aging pipes in older homes (generally those built before 1986).
If you're concerned about lead in your home water, have the water tested. There are a
number of water treatment options, including some filter pitchers, to reduce lead.
Additionally, you can minimize your exposure to lead by running the water from your
tap until it's as cold as possible before drinking it (especially first thing in the morning),
and by using only cold water for cooking and drinking (hot water can draw more lead
from the plumbing.

7. It doesn't matter whether you drink your total day's intake of water in one sitting or
7. throughout the day; as long as you're downing your daily dose, you'll enjoy all of

important to drink water throughout the day and not just all in one sitting. And, not just
when you're thirsty. In fact, by the time you feel the sensation of thirst, you body
already may have lost one to two percent of it's water, propelling it into dehydration.
