Quality Water

YCUA's mission is to provide top quality, cost effective, and environmentally safe water and wastewater services to our customers. As part of that commitment, this webpage is intended as a resource for information on water quality in our community.

Consumer Confidence Reports

YCUA’s annual Consumer Confidence Report contains important information about the source and quality of your drinking water.  This report follows the guidelines set by the U.S. Environmental Protection Agency and the Michigan Department of Environment, Great Lakes, and Energy.  Our goal is to provide you with a safe and dependable water supply.  This report illustrates that we are achieving our goal.  This report is published on our website after June 1 of each year.  If you would like to receive a paper copy of the report delivered, or if you want additional copies, please call YCUA Administration at 734.484.4600 ext. 107.  Please click on the link below for the current and previous reports. 

YCUA's Consumer Confidence Quality Water Reports

Lead and Copper

Safe drinking water is a shared responsibility.  The water that GLWA delivers to our community does not contain lead.  Lead can leach into drinking water through home plumbing fixtures, and in some cases, customer service lines.  Corrosion control reduces the risk of lead and copper from leaching into your water.  Orthophosphates are added during the treatment process as a corrosion control method to create a protective coating in service pipes throughout the system, including in your home or business.  YCUA performs required lead and copper sampling and testing in our community. Water consumers also have a responsibility to maintain the plumbing in their homes and businesses and can take steps to limit their exposure to lead. 

Exposure to lead can cause behavior problems and learning disabilities in young children and can also affect the health of adults. The United States Environmental Protection Agency (EPA) limits lead levels in your drinking water. YCUA's water quality continues to meet the requirements of Michigan's revised Lead and Copper Rule (LCR), the most stringent in the nation. In 2019, YCUA's Water System Advisory Council (WSAC) was formed to advise and assist with the creation of materials and outreach plans to educate our community about lead in drinking water and inform owners whose service lines may need replacement.


Lead Service Lines & Inventory

YCUA has made it a standard practice to replace all non-copper water service piping as part of all water main projects. The Authority is in the process of completing a materials inventory of the public and privately owned portions of water service lines. YCUA has historical data on the publicly owned portion and is now in the process of gathering data on the privately owned portion of the service lines. Data on service line material will be collected as part of our "Get the Lead Out" program, focused on finding and replacing any remaining lead service lines beginning in 2021.

Report my information for the residential water service line data collection. 

For more information, call YCUA's Service Center at 734-484-4600 ext. 307 or send an e-mail to director@ycua.org.

Per- and Polyfluoroalkyl Substances (PFAS)

PFAS are man-made compounds used in manufacturing carpet, clothing, furniture fabrics and paper food packaging. They are used to make items water- and stain-resistant. PFAS is also found in products such as firefighting foams, cleaners, cosmetics, paints, adhesives and insecticides. PFAS is known as a “forever chemical” because it does not break down in the environment.

The Great Lakes Water Authority (GLWA) has been testing for PFAS since 2009 and is pleased to assure the public that these chemicals were not detected. 

Scientists are still learning about the health effects of exposures to mixtures of PFAS compounds.  Although more research is needed, some studies in people have shown that certain PFAS may:
  • affect growth, learning, and behavior of infants and older children
  • lower a woman’s chance of getting pregnant
  • interfere with the body’s natural hormones 
  • increase cholesterol levels
  • affect the immune system
  • increase the risk of cancer
If you have medical questions, please consult with your doctor.

GLWA / YCUA PFAS Facts Flyer

The Michigan Department of Environment, Great Lakes, and Energy produced a new video to help explain what PFAS are, health risks, what the state is doing, what people can do to reduce their own exposure, and where to go for more information.


The Michigan PFAS Action Response Team (MPART) was established in 2017 to address the threat of per- and polyfluoroalkyl substances (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.  In FY2023, the Michigan legislature supported the PFAS response by appropriating funding across the 7 state agencies that make up MPART.  Learn more about the impact of that funding.

On March 14, 2023, EPA announced the proposed National Primary Drinking Water Regulation (NPDWR) for six PFAS including perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluorononanoic acid (PFNA), hexafluoropropylene oxide dimer acid (HFPO-DA, commonly known as GenX Chemicals), perfluorohexane sulfonic acid (PFHxS), and perfluorobutane sulfonic acid (PFBS). The proposed PFAS NPDWR does not require any actions until it is finalized. EPA anticipates finalizing the regulation by the end of 2023. EPA expects that if fully implemented, the rule will prevent thousands of deaths and reduce tens of thousands of serious PFAS-attributable illnesses.
