When Kathryn Pilgrim bought her Victorian home in Dunkirk, N.Y., she knew the plumbing was old. After replacing suspect pipes and installing a heavy‑metal filter, she still can’t be sure whether the service line that runs under her front yard is made of lead. Dunkirk’s water system, which serves about 5,000 homes and businesses, is nearly two years behind the inventory deadline that would tell residents like Pilgrim what material runs to their taps.
Why the inventory matters
The U.S. Environmental Protection Agency (EPA) requires every public water system to submit a list of its service‑line materials. Roughly 6,300 systems serving 3.8 million Americans have yet to provide that list, leaving residents in the dark about a major source of lead exposure. Lead is a neurotoxin that can stunt children’s development, lower IQ scores, and raise blood pressure in adults.
National scope and local impact
New York’s own data show that 45 % of Buffalo’s service lines are made of lead, the third‑highest rate among major cities, while neighboring Fredonia reports 28 %.
Across the country, the EPA estimates about 4 million homes and businesses remain connected to lead pipes. The agency has called its enforcement actions a key environmental win: about three‑quarters of drinking‑water enforcement orders issued since President Donald Trump returned to office were tied to missing inventories.
Trump administration’s stance
The Trump administration, which inherited the 2027 deadline enacted under the previous administration, has defended the aggressive timeline in court, arguing that swift replacement protects families and upholds constitutional rights to safe water. Rob Hayes, senior director of Environmental Advocates of New York, noted that the regulation is “a rare environmental rule the Trump administration has not sought to scrap,” underscoring its broad popularity.
Local officials work to uncover unknown lines
In Chicago, the city with the highest number of lead lines nationwide, crews are digging block‑by‑block to identify unknown service lines. Water quality director Patrick Schwer says the city assumes any line in a building predating 1986 is lead, per the Safe Drinking Water Act. He adds, “We are digging through every single piece of information we have associated with every single service line trying to find any indications of the material.”
In Dunkirk, officials have not responded to requests for comment, but the lag in inventory submission means residents cannot take informed precautions—such as running taps before use, employing certified filters, or cooking with cold water.
Cost and funding
Starting in 2027, utilities must replace at least 10 % of lead lines each year, typically with copper or plastic. Replacement costs range from $8,000 to $15,000 per line. The 2021 bipartisan infrastructure law provides the bulk of funding for identification and replacement, but that federal stream is ending this year, making the inventory even more critical.
What families can do now
Even an incomplete inventory can alert homeowners to potential lead service lines. Experts advise using high‑quality filters, running water before drinking or cooking, and staying informed about local water‑quality notices.
As the 2027 deadline looms, Dunkirk and thousands of other small systems must accelerate their efforts. Without a clear picture of what lies beneath the streets, both public health and the bottom line will suffer.
