Is there really such a thing as totally pure water? Not really. Almost all water contains at least some amount of minerals, for instance.
Beyond that, your drinking water might also contain tiny amounts of microorganisms and contaminants that don't necessarily pose a health threat. In fact, some of the flavor of water comes from these substances, believe it or not.
The problem isn't with your public water treatment facility. Water can become impure after it leaves a treatment plant on its way to your tap. Silt, sediment and other contaminants can build up inside water mains and household plumbing. Beyond that, there are things like runoff from storms, pesticides and acid rain that can affect your water.
In other words, it's not just lead. So, what to do? Good question.
WQA recommends getting your water tested by a certified professional, and then use a certified product such as a water filter to remove the contaminants that a test has revealed. WQA's website has a variety of resources to help. Learn more at wqa.org.
