Whether you choose tap water, bottled water or both, here are easy ways to lower your risk of contamination.

Before you drink the tap water in the morning, turn on your faucet and run it for about 20 seconds. This helps to clear out any chemicals that leached from your pipes into the water during the night.

If your tap water has a strong chlorine taste or smell, fill a container and let it sit open for several hours. Some of the chlorine will evaporate and the water will taste better.

Purchase your bottled water from a company that’s a member of the International Bottled Water Association (IBWA). You can check online at bottledwater.org, click on “What is IBWA?” and then “Brand List”.

Purchase your water from a store that turns over their supply of bottled water frequently. If they sell a lot of water, their supply is replenished more often and not as old.
