Detroit families are sounding the alarm after opening their mailboxes to find unsettling letters from local water departments last week. The notices informed residents that their water service lines might contain lead, warning of health risks and offering steps to reduce exposure. Social media platforms like the Detroit subreddit and NextDoor were flooded with reactions of confusion and concern. For many, the letters raised more questions than answers about the safety of their water supply and the steps needed to protect their households.
The communication campaign stems from Michigan’s compliance with state and federal drinking water laws. Local water systems had a deadline of October 16 to publish detailed inventories of service line materials, known as Comprehensive Distribution System Materials Inventories. They must notify residents about any lines suspected or confirmed to contain lead within 30 days. For water systems serving over 50,000 residents, these inventories must also be made accessible online.
Since 2018, Michigan has required water systems to alert residents of lead service lines within 30 days of confirmation. However, inconsistent compliance has left many in the dark. This year, the Environmental Protection Agency’s (EPA) deadlines—October 16 for inventories and November 15 for resident notifications—have enforced a new level of accountability.
Lead exposure poses serious health risks, especially for children, whose developing bodies are highly vulnerable. Even low levels of lead can result in developmental delays, learning challenges, and other lasting health problems. Adults are also at risk, facing increased chances of heart disease, high blood pressure, and kidney issues.
Scott Dean, a spokesperson for Michigan’s Department of Environment, Great Lakes, and Energy (EGLE), explained the scope of the new regulations. “The initial inventory must be publicly accessible and contain information about known lead service lines, galvanized service lines that currently are or ever were downstream of lead, or unknown service lines,” he said. These inventories are designed to give residents a clearer picture of their water infrastructure and its risks.
Dean also highlighted the EPA’s “Tier 1” notification requirement, which demands public notice within 24 hours of a lead action level exceedance. An exceedance occurs when the 90th percentile of sampled water tests surpasses 15 parts per billion of lead. Michigan’s Lead and Copper Rule will lower this threshold to 12 parts per billion starting January 1, 2025.
Metro Detroit communities such as Harper Woods, Redford Township, Livonia, Garden City, and the Shorewood Hills Subdivision in Bloomfield Township reported lead action level exceedances this year. These municipalities must now ramp up efforts to monitor lead levels, educate residents, and replace aging service lines.
Residents receiving these notifications were urged to take specific precautions. Suggestions included using lead-reducing water filters, regularly cleaning faucet aerators, and flushing water lines before use. The letters advised residents to consult water system inventories to confirm if their service lines are lead or unknown and offered resources for testing water at state-certified labs.
Bryan Peckinpaugh, a spokesperson for the Detroit Water and Sewer Department, reassured residents that Detroit’s water remains safe to drink. “This is not new information,” Peckinpaugh said, emphasizing that federal regulations require such notifications for transparency. He encouraged residents to use the city’s interactive map tool to check their service line status.
Detroit’s water department has ramped up efforts to replace its aging infrastructure. Last month, the city received $90 million in federal grant funding, enabling a significant increase in lead pipe replacements—from 700 annually to over 8,000 this year. With over 80,000 lead service lines still in use, the city aims to replace them all within a decade.
Detroit and other municipalities have adopted different methods to share inventory data. While Detroit and Highland Park use interactive ArcGIS maps, communities like Royal Oak and Rochester Hills provide downloadable spreadsheets listing service line classifications. These approaches offer transparency but also highlight the complexity of addressing lead contamination in older cities with outdated infrastructure.
Detroit isn’t alone in tackling this issue. Michigan’s Department of Health and Human Services (MDHHS) recently awarded $7 million in grants to reduce lead exposure statewide, with Detroit receiving $1.3 million. This funding supports lead abatement efforts, including removing lead-based paint, replacing hazardous plumbing, and relocating residents during remediation.
Elizabeth Hertel, MDHHS director, emphasized the importance of these efforts. “Michigan is committed to protecting families from lead exposure by working with communities across the state to reduce or eliminate all sources of lead in the home,” she said.
Other cities receiving funding include:
- Battle Creek: $1.5 million for Calhoun County
- Community Action Agency: $1.5 million for Lenawee and Hillsdale counties
- Grand Rapids: $700,000 for the Grand Rapids area
- Human Development Commission: $750,000 for Huron, Tuscola, Sanilac, Lapeer, and Bay counties
- Muskegon: $1.2 million for Muskegon County
- Delta and Menominee Counties: $700,000 for the Upper Peninsula
These funds will support activities like lead inspections, soil remediation, and replacing pre-2014 plumbing fixtures.
Communities in Detroit deserve more than letters warning about lead exposure—they deserve action. For too long, systemic neglect has left Black and working-class neighborhoods grappling with outdated infrastructure and the risks it brings. Access to clean water is a fundamental right, and addressing lead contamination is essential for protecting the health and future of every resident.
Ensuring a lead-free future means holding leaders accountable and prioritizing investment in communities that need it most. Families should not have to live in fear of the water coming from their faucets. The time to act is now, and this fight must continue until every family can trust the safety of their water.
The path to eliminating lead risks requires a coordinated effort between local governments, state agencies, and residents. For Detroit, aging infrastructure and decades of disinvestment have compounded challenges, making transparency and swift action essential. Residents can take steps to protect themselves, but systemic solutions like lead pipe replacement and improved regulations are crucial for long-term safety.
As Detroit moves toward a future free of lead exposure, this moment serves as a reminder of the importance of accountability and community engagement. Every family deserves safe drinking water—and the tools to ensure it.
