CDC Water and Health Study

Dear [Customer Name]:

I am writing to ask for your help with a study about your household’s water use and overall health.

[Utility Name] (group that provides your drinking water) and other utilities around the country have volunteered to work with the Centers for Disease Control and Prevention (CDC) on the CDC Water and Health Study. You have been selected from a list of water utility customers in your area. Because this study asks about your experiences in the last 2 weeks, it will be easiest if you respond right away while recent events are still fresh in your mind.

U.S. tap water is one of the safest and healthiest drinking water supplies in the world. To keep it as safe and healthy as possible, we want to know how people use their tap water, and how water use affects health. The goal of this study is to understand water use and whether water use habits are linked to common illnesses. Your feedback will be combined with information from customers of other water utilities around the country.

Feedback from each and every household we invite to participate is needed to give us the best understanding of everyone’s experiences.

You can fill out the survey in one of two ways:

1. Paper – fill out the enclosed paper survey and send it back to us in the envelope provided. We have already paid for the postage.

2. Internet – go to the following website: http://www.cdc.gov/healthywater/survey.html
