Drinking Water Week

May 7 - 13, 2023

Michigan recognizes national Drinking Water Week each year during the first full week of May. Drinking Water Week was established by the American Water Works Association (AWWA) and its partners, and it provides a unique opportunity for both water professionals and the communities they serve to recognize the vital role water plays in our daily lives. The Office of the Clean Water Public Advocate (OCWPA) collaborates with other state divisions and agencies in using this week to educate the public on where their drinking water comes from, how to learn about their water quality, and who to contact with questions.

During this week, Michigan also proclaims Tuesday as Private Residential Awareness Day to bring attention to the 2.6 million Michiganders who depend on private wells for their drinking water, as well the responsibilities of well owners to properly maintain and test their wells. Michigan has over one million private residential wells!  

Learn About Drinking Water

    Follow the water in the video below as it moves through the environment and becomes our drinking water. 

    What an amazing journey our water takes to get to our faucet!

    Water is supplied to your home from either a public water supply or a private well. It’s important to determine how your water is supplied to understand how your water quality is monitored and who to contact if you have water quality issues. A general rule to follow is: If you get a water bill for your water, you are on a community water supply, which is a type of public supply.

    In this video, Dewy the water drop explains how water from the environment makes its way into our homes to become our drinking water. You will learn about the water cycle, watersheds, groundwater, surface water, and the ways that drinking water can be supplied to our homes.

  • If you have a private well, scroll down to our “Resources for private residential well owners” section. If you still have questions or concerns, reach out to your local health department

    If you are on a community water supply, the best way to learn about your local water quality is by reading your water supplier’s Consumer Confidence Report (CCR), also known as an Annual Water Quality Report. Every community water supplier must provide a CCR to its customers by July 1 each year. CCRs may be delivered in different ways, such as a paper copy or via a link within your bill. If you’re not sure where to access yours, contact your local water supplier. Your local water supplier should also be your first call to answer questions or address concerns.

    If you still have concerns about your water quality visit our Drinking Water Concern System page. Here you will find frequently asked questions and answers about drinking water quality concerns, information on how to get your water tested, and steps to submit a concern. Submitted concerns are reviewed by the appropriate staff member who will follow up with you. Remember, depending on your water supply, your local health department or water supplier is likely your best resource for answering questions about your water.

    Where does our drinking water come from?

    In this video, Sara Pearson answered the question: "Where Does Our Drinking Water Come From?"

  • Most contaminants in water have no taste, color, or smell. The only way you might know if you have a problem is to test your drinking water.

    The water coming to your home may already be regularly tested for certain contaminants depending on your water supply (view supply types).

    • Type 1 community public water supplies are required to routinely test the water for certain contaminants. Your water supplier and their annual Consumer Confidence Report can provide information on testing and results.
    • Type 2 noncommunity water supplies are required to routinely test the water for certain contaminants.  Your water supplier and your local health department can provide information on testing and results.
    • Type 3 public water supplies are required to test the water when the well is constructed. Talk with your landlord or community association to find out who is responsible for the well, testing, and maintenance and about testing schedules and results.
    • If you have a private residential well, testing is your responsibility. Check with your local health department to learn if there are any drinking water concerns in your area and what testing is recommended. MDHHS recommends annual testing for Coliform Bacteria and E. coli, nitrate, and nitrite and testing every 3-5 years for arsenic, copper, and lead. Consider testing for PFAS every 3-5 years as well, unless there is detection at the onset, in which case you should consider resampling each year.

    If you have concerns about your water quality or want to know more about your water, consider doing your own testing.

    Drinking Water Testing for PFAS

    If you live near a potential PFAS source or if you are unsure, consider testing your drinking water via a certified PFAS Laboratory. Call the MDHHS Environmental Health Hotline at 800-648-6942 to see if your home is in an area that is under investigation for PFAS, in which case MDHHS may be able to test your water for free.

  • Healthy Water Healthy Kids Logo for the School Drinking Water Training Program

    Healthy water is important to everyone, especially for children as they are still growing and learning, and Michigan’s children spent a significant portion of their day in school or childcare facilities. Many of these facilities receive their water from a public water supply.

    The School Drinking Water Program, within EGLE, works with schools and childcare facilities to monitor water quality.

    EGLE Classroom - Introduction to PFAS

    Per- and polyfluoroalkyl substances (PFAS) are a large family of man-made chemicals that contain carbon, fluorine, and other elements and are found in a variety of products including firefighting foams, household products such as non-stick cookware, food packaging, and stain and water repellants.

    People can be exposed to PFAS in a variety of ways, including drinking water contaminated with PFAS. 

    PFAS Cycle

    PFAS chemicals don't break down and can accumulate over time. In recent years, experts have become increasingly concerned by the potential effects of high concentrations of PFAS on human health. PFAS move easily through the ground and may get into groundwater that is used for some water supplies or for private drinking water wells.  
    Take a closer look at the PFAS cycle
    Why are my PFAS test results different than my neighbors? Video

    Why are my PFAS test results different than my neighbors?

    How to find out if PFAS may be a concern in your drinking water depends, again, on how you get your water. If you’re on a public supply, your water is already routinely tested for the seven PFAS chemicals regulated under the Michigan Safe Drinking Water Act.

    If you have a private well, you can find out if you are in or near a PFAS Site or Area of Interest and/or test your water for PFAS. Find out about why results may vary from well to well with this short video. 

    In 2019, Governor Gretchen Whitmer signed Executive Order 2019-3, establishing the Michigan PFAS Action Response Team (MPART) as an established, enduring body to address the threat of PFAS contamination in Michigan, protect public health, and ensure the safety of Michigan's land, air, and water, while facilitating inter-agency coordination, increasing transparency, and requiring clear standards to ensure accountability.

  • A well and its water are ultimately the responsibility of the well owner. If you have a private well, there are things that you should do to monitor your well system and your drinking water to help protect your family’s health and ensure quality tap water. 

    Check with your local health department to learn if there are any drinking water concerns in your area and what testing is recommended. MDHHS recommends yearly testing for Coliform Bacteria and E. coli, nitrate, and nitrite and testing every 3-5 years for arsenic, copper, and lead. If you live near a potential PFAS source or if you are unsure, consider testing your drinking water via a certified PFAS Laboratory. Call the MDHHS Drinking Water Hotline at 844-934-1315 to see if your home is in an area that is under investigation for PFAS, in which case MDHHS may be able to test your water for free. 

    Great Lakes Community Action Partnership, Rural Community Assistance Program Water Well Assessment Program provides rural residents with no-cost well evaluations to help well owners determine possible sources of well contamination and other safety concerns, and a Household Water Well Assistance program that provides low-interest financing for well repair or construction.

  • The Michigan Department of Environment, Great Lakes, and Energy (EGLE) is responsible for enforcing the Federal Safe Drinking Water Act under the legislative authority of the Michigan Safe Drinking Water Act, which means that EGLE regulates the public water supplies to ensure that they are complying with state and federal requirements to provide clean water to Michigan residents. There are approximately 1,400 community water supplies and 10,000 noncommunity water supplies regulated by EGLE.

    Additionally, EGLE also regulates the water well drilling industry. Michigan has nearly 1.12 million households served by private wells, with approximately 15,000 domestic wells drilled each year. EGLE investigates drinking water well contamination and oversees remedial activities at sites of groundwater contamination affecting drinking water wells.

    Local health departments (LHDs) are the primary regulatory agencies with respect to residential wells. They are required to maintain a list of environmental contaminants within their jurisdiction, and they consider this information when they issue permits for new wells. LHDs work with Michigan residents to ensure compliance with monitoring and routine inspections of Type II and III wells.

  • The Clean Water Ambassador Initiative is a statewide effort designed to improve education and communication concerning water quality in Michigan. Clean Water Ambassadors are invited to attend virtual monthly meetings, share information via social media with their communities, and learn about drinking water issues. Ambassadors are also kept up to date on emerging legislation, conferences, and water infrastructure funding opportunities. If you are at least 18 years old and live in Michigan, you can become a Clean Water Ambassador too!

    “Thank you, Clean Water Ambassadors! The time you give to learn more about Michigan’s drinking water, spread information to your community, and provide valuable feedback is important and appreciated. I look forward to our work together!”
