The claim that Flint's water was safe to drink was repeated by state and local officials for more than a year after Flint, Michigan, switched its water source in April 2014. Residents complained that the water was discolored, smelled and caused rashes. Officials assured them the water met standards. In fact, the river water was corrosive and had not been treated with corrosion control, causing lead to leach from old pipes into homes. Independent researchers documented high lead levels in tap water and a rise in the proportion of children with elevated blood lead. An outbreak of Legionnaires' disease linked to the water system killed at least twelve people. The Flint water crisis became one of the most notorious public health failures in recent US history.
The claim
As complaints mounted, officials from the Michigan Department of Environmental Quality (MDEQ) and the city said the water met federal and state standards. When researchers raised alarms about lead in 2015, a state spokesperson publicly dismissed their findings, and state officials initially disputed a pediatrician's data showing rising blood lead levels in children.
Origin
In 2014 Flint, a majority Black city with high poverty, was under the control of a state-appointed emergency manager. To save money, the city stopped buying treated water from Detroit and began using the Flint River as an interim source while a new pipeline was built. MDEQ did not require the city to add corrosion control chemicals, such as orthophosphate, which coat pipes and prevent lead from dissolving. Federal rules required corrosion control for a system of Flint's size; investigators later concluded MDEQ had misapplied them.
What the evidence shows
- Corrosive water. The river water was more corrosive than the treated Detroit water. In October 2014 General Motors stopped using Flint water at its engine plant because it was corroding parts.
- Lead in homes. In early 2015 Flint resident LeeAnne Walters reported very high lead levels in her home's water. Miguel Del Toral, an EPA water expert, wrote an internal memo in June 2015 warning of a lack of corrosion control. In August and September 2015 a team led by Marc Edwards of Virginia Tech tested water from hundreds of homes and found widespread elevated lead levels.
- Children's blood lead. In September 2015 Dr. Mona Hanna-Attisha, a pediatrician at Hurley Medical Center, found that the percentage of young children with elevated blood lead levels had roughly doubled after the switch, with larger increases in the most affected neighborhoods. State officials initially questioned her analysis before acknowledging it was correct. Lead exposure in children can cause lasting harm to cognitive development; there is no known safe level.
- Testing flaws. Investigations found that official sampling methods, such as asking residents to run taps before sampling, could understate lead levels, and that some high samples had been excluded.
- Legionnaires' disease. An outbreak in the Flint area in 2014 and 2015 sickened at least 90 people and killed at least 12. Researchers linked it to the water switch.
In October 2015 Flint returned to Detroit's water system. In January 2016 state and federal emergencies were declared. A task force appointed by the governor concluded that MDEQ bore primary responsibility and that environmental injustice had played a role.
Aftermath
The city replaced thousands of lead service lines. In 2020 the State of Michigan agreed to pay about $600 million toward a settlement with Flint residents, which grew to more than $620 million with contributions from other defendants. Criminal charges were brought against several state officials, including former Governor Rick Snyder, but most were dismissed after the Michigan Supreme Court ruled in 2022 that the method used to obtain the indictments was improper.
Lessons for readers
- Official assurances are not a substitute for independent testing, especially when residents report problems.
- Ask how samples were taken; methods can hide problems.
- Listen to the experiences of affected communities.
- Cost-cutting decisions about public health infrastructure can have severe consequences.
- Independent scientists and local doctors can play a crucial role in exposing failures.
