Nearly a tenth of the nation’s drinking water service lines contain lead, new data shows.
States With the Most Lead Pipes

A piece of old lead pipe is seen in 2016 in Chicago.
In a first-of-its-kind report, the Environmental Protection Agency has released a comprehensive assessment on lead pipe infrastructure across the United States, revealing that an estimated total of 9.2 million lead pipes serviced American homes in 2021.
According to the report, lead service lines are estimated to make up over 9% of the entire national service line infrastructure, exposing much of America’s drinking water to lead contamination.
The EPA says there are no safe levels of lead in children’s blood, as lead exposure has been tied to an array of adverse health effects in children, including behavioral problems, lower IQ and slowed growth. In adults, lead exposure is linked with decreased cardiovascular health and kidney function, and lead exposure in pregnant women is linked to premature births.
The bulk of the nation’s lead pipe infrastructure is concentrated in a handful of states, including many of the Rust Belt states in the Great Lakes region. Florida has the most lead service lines in the country, with its 1.16 million lines accounting for 12.6% of the country’s total. Over 50% of the national service lines are concentrated in six states: Florida, Illinois (11.4%), Ohio (8.1%), Pennsylvania (7.5%), Texas (7.1%) and New York (5.4%).
Lead service lines are far less common west of the Mississippi River, with Texas as the lone exception. Notably, California’s service line infrastructure, which serves the largest state population over the third-largest area, has less than 13,500 lead service lines, or about 0.15% of the national total.
Federal law prohibits installing new lead plumbing because of its dangers to health. In 2021, the Biden Administration announced an aggressive plan to replace all lead service lines in the next decade as part of the Bipartisan Infrastructure Law, and earlier this year the EPA announced that $1.2 billion had already been distributed to 23 states to address that goal. But the costs associated with such an effort are significant. Over the next two decades, the EPA report estimates that $625 billion is needed to address the challenges with drinking water infrastructure.

Lead exposure does not impact all American demographics evenly. The Centers for Disease Control and Prevention published a study in 2021 indicating that non-Hispanic Black or African American children were at particular risk, as well as children living in areas with higher poverty rates.
Although the Safe Drinking Water Act, which was enacted 1974 and amended most recently in 1996, aims to ensure the public’s access to contaminant-free water, large-scale issues with drinking water distribution systems are still prevalent. Spikes in the rates of lead in children’s blood in 2015 sparked the start of a years-long water crisis in Flint, Michigan. The city of Jackson, Mississippi, which endured days with a full water outage last August and September, has ongoing projects to reduce elevated levels of lead in its water supply, and lead contamination has led to crises in Newark, New Jersey, Chicago and Washington, D.C., among other communities.
These are the states with the most lead pipes, according to the EPA:
- Florida
- Illinois
- Ohio
- Pennsylvania
- Texas
- New York
- Tennessee
- North Carolina
- New Jersey
- Wisconsin
