US Cities Lagging on Lead Pipe Inventory, Endangering Residents

In Dunkirk, New York, resident Kathryn Pilgrim faces uncertainty about her home's water safety due to the city's delay in creating a lead pipe inventory. This situation reflects a broader national issue, with over 1,300 public water systems, including Dunkirk's, failing to meet the U.S. Environmental Protection Agency's (EPA) October 2024 deadline for documenting lead service lines. These inventories are vital for meeting a 2027 mandate requiring most drinking water providers to replace lead pipes within a decade.

Nationwide, roughly 6,300 water systems serving 3.8 million Americans have not submitted their required lists of lead service lines. Lead is a potent neurotoxin, and approximately 4 million homes and businesses are still connected via these hazardous pipes. The EPA has prioritized lead line replacement, with many enforcement actions targeting missing inventories, a strategy largely continued from the Trump administration.

Identifying these lines is a challenging task. Many utilities, like Chicago, are still working to determine the material of nearly 10% of their service lines. Incomplete or lost records from decades past, when lead was a common material for water pipes, contribute to the difficulty. Cities like Buffalo and Fredonia, New York, report high percentages of lead lines, underscoring the widespread nature of this infrastructure problem.

Challenges extend to funding and logistics. Replacing lead pipes is expensive, costing between $8,000 and $15,000 per line. While federal funding is available through the 2021 infrastructure law, water systems that haven't completed their inventories risk falling further behind, especially as national efforts shift towards actual replacements. Failing to document these lines not only impedes replacement schedules but also leaves residents uninformed about potential lead exposure risks.
