For most of us, the act of drinking a glass of water is an exercise in blind trust. We turn a handle, the liquid flows, and we assume This proves safe because the system is designed to be invisible. But beneath the pavement and behind the drywall lies one of the most complex and aging pieces of infrastructure in North America, a network that requires constant vigilance and significant capital investment to maintain.
This vulnerability is the catalyst for Drinking Water Week, observed from May 3-9. While the event is often framed as a celebration of water professionals, for the consumer, it serves as a critical annual audit. Led by the American Water Works Association (AWWA) for over four decades, the initiative aims to bridge the gap between the technical reality of water treatment and the public’s general lack of awareness regarding where their water actually originates.
In Michigan, the effort is spearheaded by the Department of Environment, Great Lakes, and Energy (EGLE) through the Office of the Clean Water Public Advocate. The state’s approach is particularly urgent given its unique geography and a history of high-profile water crises that have made “water quality” a household term. The goal this year is simple but ambitious: move the public from passive consumption to active stewardship.
Understanding the source of your water is not just a matter of curiosity. it is a matter of risk management. Depending on whether you are connected to a municipal grid or rely on a private well, your legal protections, testing requirements, and financial responsibilities differ wildly. As Kris Donaldson, EGLE’s clean water public advocate, notes, protecting the supply starts with everything from safeguarding source waters to the mundane task of updating old plumbing fixtures in a home.
The Regulatory Divide: Public vs. Private Supplies
The first step in assessing your water safety is determining which regulatory regime governs your tap. For the majority of urban and suburban residents, water is a utility service. If you receive a monthly bill, you are likely part of a community public water supply. Under the federal Safe Drinking Water Act, these suppliers are mandated to conduct routine testing for a specific battery of contaminants.
The primary tool for transparency here is the Consumer Confidence Report (CCR), also known as the Annual Water Quality Report. These documents are the “financial statements” of water safety, detailing exactly what was detected in the water and whether those levels exceed maximum contaminant levels (MCLs) set by the EPA. These reports are often delivered via paper or linked in digital bills, but they are frequently overlooked. For any resident with concerns, the CCR is the first point of evidence to review before contacting a local supplier.
However, a significant portion of the population exists outside this safety net. In Michigan alone, approximately 2.6 million residents rely on private residential wells. For these individuals, the “utility” is the homeowner. There is no monthly bill, but there is also no mandated routine testing once the well is installed. This creates a precarious situation where the owner is solely responsible for the health of their supply.
To highlight this disparity, Michigan designates May 7 as Private Residential Well Awareness Day. The risk for well owners is that most dangerous contaminants—including nitrates, arsenic, or PFAS—are colorless, odorless, and tasteless. Without a certified laboratory test, there is virtually no way to know if a well has been compromised by runoff or geological shifts.
| Feature | Community Public Supply | Private Residential Well |
|---|---|---|
| Testing Requirement | Mandated routine testing | Owner’s responsibility |
| Transparency Tool | Annual Consumer Confidence Report | Private lab results |
| Regulation | EPA & State Oversight | Local health department guidance |
| Primary Contact | Water Utility/Supplier | Certified Well Contractor/Health Dept |
The Infrastructure Gap and Home Stewardship
Even when the water leaving a treatment plant is pristine, the “last mile” of delivery—the pipes entering a home—can introduce new risks. This is where the business of homeownership intersects with public health. Lead service lines and aging galvanized steel pipes can leach contaminants into the water long after it has left the municipal system.
Updating plumbing and fixtures is not merely a home improvement project; it is a health intervention. For those in older homes, the transition to lead-free fixtures and the replacement of old service lines are the most effective ways to ensure that the quality guaranteed in a CCR actually reaches the glass. This is a significant financial burden for many homeowners, but it remains the only permanent solution to internal contamination.
For the next generation, EGLE has integrated educational components into Drinking Water Week, including a “Lending Station” that provides models and hands-on demonstration resources for educators. By treating water literacy as a foundational skill, the state hopes to reduce the long-term costs of environmental remediation by fostering a culture of prevention.
Practical Steps for Water Auditing
For residents looking to move beyond the general awareness of Drinking Water Week, the following sequence is recommended for a comprehensive water audit:
- Identify Your Source: Determine if you are on a community supply, a non-community public supply (like a school or office), or a private well.
- Access Your Data: For public water users, locate your most recent Consumer Confidence Report. For well users, schedule a test with a certified laboratory.
- Consult Local Health Departments: Check for area-specific concerns, such as agricultural runoff or industrial plumes, which may require testing for contaminants not included in standard panels.
- Inspect Internal Plumbing: Evaluate the age of your pipes and fixtures, particularly in homes built before 1986, when lead was more common in solder and brass.

As the observation of Drinking Water Week concludes, the focus shifts toward the next cycle of reporting. Residents should look for the release of the next round of Annual Water Quality Reports, typically distributed in the summer months, to track changes in their local water chemistry over time.
