PFAS Contaminations in Small Town U.S. Drinking Water

CLIFF NOTES
● Small and rural systems face PFAS contamination.
● Limited funding slows treatment upgrades.
● Residents face prolonged exposure.
● Federal aid can be delayed.
● Point-of-use filtration offers protection.

Recent data released by the U.S. Environmental Protection Agency (EPA) has exposed the breadth of PFAS contamination across the nation’s drinking water systems. A USA TODAY analysis shows 839 utilities exceeded new federal limits for two notorious types of these chemicals: PFOA and PFOS. These water systems serve roughly 46 million Americans.

PFAS, short for per- and polyfluoroalkyl substances, are a group of man-made compounds designed to resist heat, oil, and water. Their durability has earned them the nickname “forever chemicals,” as they persist in the environment and accumulate in human bodies. Long-term exposure is linked to cancers, immune system disruptions, and other serious health effects.

Smaller Communities See High Levels of Contamination

Although larger cities tend to fail EPA standards more often, it is small towns that report the most extreme contamination levels. In Nashville, North Carolina, a community of 6,000, one well tested at 490 parts per trillion (ppt) for PFOS—over 120 times the EPA’s limit of 4 ppt.

In Emmaus, Pennsylvania, the situation has been equally troubling. Several of the borough’s wells exceeded federal thresholds. At the borough’s waterworks building, PFOS levels averaged 32 times the limit, while PFOA levels were about five times above acceptable levels.

Borough manager Shane Pepe pointed to a local firefighter training facility as the source of the contamination. “While our firefighters are practicing to save your life, they had no idea that at the same time the water system was getting poisoned,” he said.

The Source: Firefighting Foam and Industrial Accountability

PFAS compounds have been commonly used in firefighting foams, especially in training exercises. Over decades, these chemicals seeped into aquifers, often unnoticed until widespread testing revealed the scope.

“These firefighting foam companies knew what was in the water and never notified anybody,” said Pepe, expressing frustration with chemical manufacturers. Emmaus opted out of a $4 million class-action settlement and instead is pursuing its own lawsuit. Among the defendants is 3M, which did not directly respond to the allegations but stated it committed $12 billion toward water supplier settlements and will end PFAS production by the end of 2025.

DuPont, another named manufacturer, declined to comment due to ongoing litigation.

Community Action in Emmaus

Emmaus discovered its contamination in late 2021 during state-mandated testing. The utility promptly shut down the most affected well and began investigating treatment solutions. Rather than purchasing outside water, residents supported restoring their own supply.

The town secured over $9 million in grants and nearly $2 million in loans to build a filtration system. The setup will include four large tanks filled with granular activated carbon, a material capable of removing PFAS from drinking water. Pepe said construction should finish by June 2026.

The system’s maintenance will cost about $100,000 annually to replace carbon filters. Emmaus will raise water rates slightly to cover this. “Had we not gotten the grant,” Pepe said, “instantly our folks would have been paying four times what they pay today. Instantly. And that would have been for the next 20 to 30 years.”

Who Pays for Clean Water?

Hundreds of other small water systems face similar dilemmas. Many local officials argue that the burden of funding PFAS removal shouldn’t fall on residents but on the manufacturers responsible for the pollution.

Some water utility associations have taken legal action against the EPA, arguing that the agency failed to follow proper procedures when implementing the new PFAS regulations. The lawsuit remains in limbo. A federal judge has given the EPA until September 10 to clarify its regulatory stance.

Public Health Comes First

Despite legal uncertainty, local leaders like Pepe stress the importance of acting swiftly. “We are being told by environmental agencies that these chemicals in the water are bad and have the potential to cause cancer and other illnesses,” he said. “We have a duty to mitigate this as quickly as possible, and so that’s exactly what we’re doing.”

Solutions for Your Family & Home

To ensure long-term protection from PFAS contamination, experts recommend installing reverse osmosis filtration systems. These systems push water through a semi-permeable membrane that blocks harmful chemicals like PFOA and PFOS. Whole-home water conditioners, when used in combination, can protect plumbing systems from scale and improve water quality further.

Such systems offer reliable, at-home defense against forever chemicals, especially in areas with high contamination levels. They provide peace of mind for families seeking to reduce long-term health risks from their water supply.
