Residents of Newburgh, New York, where drinking water was contaminated with the industrial compounds known as PFAS, face an elevated exposure burden compared to state and national averages, according to federal EPA data and consumer water records for ZIP code 12550. The water system serving approximately 29,000 people in Newburgh has been flagged for PFAS detection, and the city carries 16 recorded water quality violations in the five-year EPA compliance window.
Newburgh's PFAS story is not new. In 2016, testing revealed that Washington Lake -- a reservoir that supplies the city's drinking water -- had been contaminated with PFOS, a type of PFAS, traced to firefighting foam used for decades at the adjacent Stewart Air National Guard Base. New York state listed the area as a Superfund site and provided Newburgh with an alternate water supply. The case drew national attention as one of the earliest documented instances of military-base PFAS contamination affecting a municipal water system in the Northeast.
The industrial compounds known as PFAS are linked to cancer, reproductive and developmental harm, liver problems, and immune dysfunction. They stay in the body for years -- and persist in the environment indefinitely. And they have contaminated thousands of sites around the country, including hundreds where the military used firefighting foam laced with the chemicals.
By 2006, the Environmental Protection Agency coordinated an industry-wide phase-out of PFOA and PFOS, both of which had been used in firefighting foam and various stain-resistant and nonstick products. Yet PFAS detection in Newburgh's water supply, documented through the EPA's Unregulated Contaminant Monitoring Rule cycle 5 (UCMR5) program, remains an active finding. Current EPA records for ZIP 12550 show a detected level of 0.0066 micrograms per liter -- a concentration below the agency's current maximum contaminant level, but one that public health researchers have argued fails to reflect the evidence on low-dose, long-term exposure.
Linda Birnbaum, who retired as director of the National Institute for Environmental Health Sciences in 2019, has noted that the EPA's safety thresholds for PFAS in drinking water do not reflect the evidence that extremely low levels of the chemicals can cause cancer and other health problems. The question of what level is actually safe has been the subject of ongoing scientific dispute.
Voluminous research has already shown links between PFAS and a wide range of health effects, including weakened immune response, reproductive difficulties, hormonal imbalances, and obesity. The cancers that have been clearly linked to the chemicals include testicular cancer, kidney cancer, and prostate cancer. Studies of people who lived near industrial plants that released PFOA that released PFOA into public water supplies in West Virginia and Ohio, conducted between 2005 and 2013, showed that exposure to the chemical was "more probably than not" linked to elevated rates of testicular and kidney cancer, cholesterol, thyroid disease, and preeclampsia.

For Newburgh residents, the regulatory picture is layered. In addition to the PFAS flag, ZipCheckup's home safety profile for 12550 reflects a composite safety score of 46 out of 100 -- grade D -- drawing on EPA drinking water data, FEMA flood records, and federal housing data. The score has declined 10 points over the past 90 days. One health-based violation remains unresolved in the EPA system. The city's lead reading of 0.0015 milligrams per liter is well below the federal action level of 0.015 milligrams per liter, but the housing stock -- 53 percent built before 1970, with a median construction year of 1952 -- carries an elevated lead pipe risk profile. The area also sits in EPA Radon Zone 1, the agency's highest-risk classification, and carries 107 cumulative NFIP flood insurance claims.
What was less clear to many Newburgh families in the years following 2016 was how continued low-level exposure would affect their households. PFAS, researchers have established, can cross the placenta, showing up in cord blood and newborns. They also accumulate in breast milk. And several studies have shown children to be particularly vulnerable to their effects. Some state officials encountered at community meetings seemed more interested in reassurance than in giving residents a full accounting of the risks.
The military has pointed to the fact that PFAS are not yet officially classified as hazardous substances under Superfund in justifying decisions not to accelerate cleanup in contested cases. Without that designation, polluted communities have faced significant legal and financial barriers to compelling responsible parties to pay for remediation. In Newburgh, the state's alternate supply decision addressed the most acute exposure pathway, but the broader regulatory picture for legacy contamination from Stewart remains unsettled.
Although it is now clear that thousands of sites in the United States have been contaminated with PFAS from firefighting foam and industrial discharges, surprisingly few systematic health studies have been conducted in affected ZIP codes. "It's infuriating that the more these PFAS manufacturers contaminate the planet, the more difficult it is to do effective human health studies, as there are fewer and fewer 'uncontaminated' populations to compare to," said Robert Bilott, the attorney who led the class-action litigation that produced the most extensive set of PFAS health findings to date.
The cumulative picture in Newburgh -- legacy military contamination, ongoing PFAS detection, aging infrastructure, high flood exposure, and Zone 1 radon risk -- describes a community navigating an unusually dense set of environmental burdens. The EPA data on file for ZIP 12550 suggests those burdens have not meaningfully receded.
