Cincinnati.com: Forever chemicals in Ohio's drinking water: Why Cincinnati is better off than Indian Hill

UC expert talks about the health threats from PFAS

New data from the U.S. Environmental Protection Agency shows that industrial pollutants, known as forever chemicals, which are linked to cancer and other serious ailments, are rarely detected in samples of drinking water from Cincinnati and most nearby communities.

The chemicals turn up in drinking water all over Greater Cincinnati, but how many toxins – and how much of them – flow from your tap depends on where you live. Cincinnati.com posted a story on PFAS, reporting that in Northern Kentucky and Colerain and Springfield townships, trace amounts are sometimes found at levels exceeding the EPA's minimum reporting limits.

Water districts that serve Indian Hill, Terrace Park and Loveland found the largest amount of forever chemicals in the area, with some samples measuring three to four times the reporting limits. In the Cincinnati.com article one of the experts cited was Susan Pinney, PhD, of the Department of Environmental and Public Health Sciences at the UC College of Medicine.

Pinney said the half-life of PFAS compounds — the amount of time it takes the chemicals to lose half their toxicity — is about four years in the human body.

Because they take so long to break down in the body and in the environment, the amount of toxicity can build up in people who are regularly exposed to the compounds, which is why they are called “forever chemicals.”

Overhauling water treatment systems is an expensive process which poses challenges for some communities which can't afford to make the needed changes.

Every solution comes with costs, said Pinney. But she said the tougher regulations are necessary. She recently led a study that linked one PFAS compound to delays in the physical development of girls.

"As we continue to do research," she said, "we find there are health effects at lower and lower levels."

An app that uses an AI model to read a single-lead ECG from a smartwatch can detect structural heart disease, researchers reported at the 2025 Scientific Sessions of the American Heart Association. Although the technology requires further validation, researchers said it could help improve the identification of patients with heart failure, valvular conditions and left ventricular hypertrophy before they become symptomatic, which could improve the prognosis for people with these conditions.
