Dear [Customer Name]:

A few days from now you will receive a brief survey for an important public health study about water and health. The Centers for Disease Control and Prevention (CDC) is working with your local water utility and other water utilities around the country to understand the connections between water use and health. This study is important because it will help us keep our drinking water safe and we need your help!

You have been selected at random from a list of water utility customers in your area. We are writing in advance because some people like to know ahead of time that they will be asked to participate.

The survey will take about 12 minutes to complete. You will be able to choose to return the survey by mail or complete it online using a personal code. The survey will ask about your household water use, foods and beverages you consume, and your overall health over a 3-week period.

Participation is voluntary, but we hope you will take a few minutes to help us when the survey packet arrives. It’s only with the generous help of people like you that our study can be successful!

Thank you for your time and consideration.

Sincerely,

Julia Gargano, PhD

Epidemiologist/Study Lead

Centers for Disease Control and Prevention

P.S. Please watch for the CDC Water and Health Study packet within the next week. We will be enclosing a small token of appreciation as a way of saying thanks.
