New research from the University of Cincinnati (UC) reveals that residents of the Mid-Ohio River Valley (from Evansville, Indiana, north to Huntington, West Virginia) had higher than normal levels of perfluorooctanoic acid (PFOA) based on blood samples collected over a 22-year span. The exposure source was likely from drinking water contaminated by industrial discharges upriver.

The study, appearing in the latest publication of Environmental Pollution, looked at levels of PFOA and 10 other per- and polyfluoroalkyl substances (PFAS) in 931 Mid-Ohio River Valley residents, testing blood serum samples collected between 1991 and 2013, to determine whether the Ohio River and Ohio River Aquifer were sources of exposure. This is the first study of PFOA serum concentrations in U.S. residents in the 1990s.

"These Mid-Ohio River Valley residents appear to have had concentrations of PFOA in their bloodstream at higher than average U.S. levels," says Susan Pinney, PhD, professor in the Department of Environmental Health at the UC College of Medicine, a member of both the Cincinnati Cancer Consortium and UC Cancer Institute and senior author of the study.

Ohio River PFOA concentrations downstream were elevated, suggesting Mid-Ohio River Valley residents were exposed through drinking water, primarily contaminated by industrial discharges as far as 666 kilometers (413 miles) upstream. Industrial discharges of PFOA to the Ohio River, contaminating water systems near Parkersburg, West Virginia, were previously associated with nearby residents' serum PFOA concentrations above U.S. general population medians.

[...] Pinney points out that the primary concern with PFCs/PFOA is that they take a very long time to leave the human body, and studies indicate that exposure to PFOA and PFOS over certain levels may result in adverse health effects, including developmental effects, liver and tissue damage and immune and thyroid impacts.

    Or, you know, citizens could vote for local government that will actually monitor and track water pollutants. I found all these water issues confusing until I realized I live in one of the few places where city waste/stormwater does testing of the system and backtracks illegal chemical dumping.

    Its like you think democrats cant be bought off by monsanto, dupont, and dow. Keep drinking that two party koolaid, meanwhile both the dems and reps are pouring slow death into your cup. Only difference is that one side kills you and your kids, and the other kills your kids and their kids.

    You are absolutely correct, but acting locally to improve sourcing and filtration doesn't help the large numbers of folks with no access to municipal water and have to rely on their own wells for household water. The small-scale purification technology available to households, both rural and urban, has far to go in terms of cost effectiveness. Filtering for specific impurities is expensive and complicated.

    I know a bit about practical water chemistry, having worked in both nuclear power plants and pharmaceuticals. Sure, distillation, reverse-osmosis, and deionization systems can make clean water alright, so clean the water produced is poisonous to drink. How do we replicate near-natural potable water efficiently? That's the challenge I see.

    Even with regulatory steps to control pollution at the source, we have far to go technologically to mitigate the damage already done. There's an opportunity here.

    You must live in some utopia where local government actually has some powers to control pollution. In the USA, this isn't true.

    Without regulations limiting pollution, the companies that are responsible will face zero consequences for their actions. Tracking pollutants is pointless unless those responsible can be forced to stop polluting.
