The CDC Water and Health Study is a research project that will help public health researchers better understand the links between water use and health in communities across the United States. The study goal is to understand water use and whether water use habits are linked to common illnesses.

U.S. tap water is one of the safest and healthiest drinking water supplies in the world. To continue to maintain and improve our safe, healthy water supply, The Centers for Disease Control and Prevention (CDC) conducts research, develops programs, and implements projects designed to find links between community health and behavioral practices and water supply characteristics.

Over the next 2 years, selected water utility customers will be invited to participate in this study. Every person who participates helps answer important scientific questions - and makes sure that their community is represented in this national effort.

As a participant, you have a special opportunity to help lead the way in keeping our water supply clean, safe, and healthy!


Frequently Asked Questions


General Study Information

What is this study? How will the study work?

The CDC Water and Health Study is a research project that will help public health researchers better understand the links between water use and health in communities across the U.S. The study goal is to understand water use and whether water use habits are linked to common illnesses.

If you received mail from the CDC, your water utility (group that provides your drinking water) provided your contact information to the CDC study team. Selected customers will be mailed a survey that asks about water use and health. You can fill out the paper survey and return it in the postage-paid envelope, or you can fill out the survey online using the secure login information provided in your survey packet.

 

What’s the purpose of the study?

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. This information will be used to help make our water even safer.

Why do you want me to participate?

We want to understand all the ways people in your community use their water, and everyone’s experiences are important to the study. We’ll be asking selected water utility customers across the country to participate in this research study over the next 2 years. Each and every household we invite is needed to give us the best understanding of everyone’s experiences.

Even if you don’t drink your tap water, your participation is still essential.

Why did you pick my community?

Several utilities from around the country have volunteered to work with the CDC on the Water and Health Study. By agreeing to be part of this study, your utility and its customers (like you) are providing an important contribution to public health.

We are selecting water systems that are typical of those found across the country. Being selected for the study does not mean that there is anything unusual about the water service in your community, and we will not be changing your water in any way as a part of this study.

Does being selected for the study mean there is something wrong with my water?

No. Being selected for the study does not mean that there is anything unusual about the water service in your community, and the study team will not be changing your water in any way as a part of this study. The CDC study team is selecting drinking water systems that are typical of those found across the country. If you are selected, your water utility volunteered to work with the CDC on this study.


About Being a Study Participant

What is involved in participating? What will you ask of me?

If you are selected to participate, the CDC study team will mail you an introductory letter explaining the study, followed by a survey packet. The survey asks about your household’s recent water use and health and will only take about 12 minutes to complete. You can either complete the paper survey and mail it back to the CDC using the postage-paid envelope included in the survey packet or complete the survey online using your secure login information found on the label of your survey booklet.

What information will be collected?

The CDC study team will send you a household survey that asks about your and your household’s (family members and roommates) recent water use and health. The survey will also ask for basic demographic information (age, race, and ethnicity) to help the study team better understand if the survey is representative of your community.

If I’m selected, how will I be contacted?

The CDC study team will contact you by mail. They will send you a letter to introduce the study and let you know to look out for a survey packet, which will also come in the mail. You can either complete the paper survey and mail it back to CDC using a postage-paid envelope or complete the survey online using your secure login information found on the label of your survey booklet. The study team might contact water customers by phone or e-mail to encourage participation. Study personnel and utility staff will NOT enter your home.

What if I don’t want to participate?

Your participation is optional. You can ignore the survey mailings or return a blank survey in the mail to CDC to communicate that you do not wish to participate.


Costs and Benefits

What are the costs of participating?

There are no costs associated with study participation. There are no known health risks associated with study participation.

What are the benefits of participating?

Your participation can help us learn how to continue to maintain a safe, healthy water supply. You will not receive any monetary benefits from participating.


Personal Information (For Selected Study Participants)

How did you get my personal information?

If you received mail from the CDC, your water utility volunteered to work with the CDC on this study and shared limited customer contact information (i.e., names and addresses) with the CDC study team so that survey materials could be mailed to you. Data were securely transferred to the CDC.

What happens with my personal information?

Your contact information will only be used for survey purposes and will not be shared with anyone outside of the CDC study team. Extra security measures are taken to protect your personal information.

Will my information be kept private?

Yes. When the study is complete, your contact information will be removed from our files. No personal information about you will appear on any report. Survey responses will be treated in a secure manner and will not be disclosed, unless otherwise compelled by law.

Will companies or other groups see my personal information?

No, your contact information will only be shared with the CDC study team to be used for study purposes. Your survey responses will be combined with responses from other survey participants. Your individual information will not be included in any report.

I don’t want to provide you with the initials, ages, or race of my family members. Is that OK?

All of the survey questions are optional. The survey collects information on age and race so that the study team can make sure that survey participants are representative of your community. It is okay to provide fake initials of family members.
