Ever wonder what’s in the world’s rivers besides water? Spoiler alert: it’s not great — but the research behind it is.

CSN’s own Mr. Josh Monk has co-authored a major new study that digs into what scientists call “emerging contaminants” things like pharmaceuticals, illicit drugs, and PFAS (those stubborn “forever chemicals” you hear about in the news). His team analyzed data from more than 100 studies in 46 countries and found that these substances are showing up in surface waters all over the world.

The big takeaway? Everyday medications like ibuprofen, acetaminophen, and even metformin are entering our rivers in high enough concentrations to impact aquatic life. PFAS, which don’t break down easily, were found at concerning levels too especially in areas without effective wastewater treatment.

Monk’s research shines a spotlight on a global problem and shows just how much work is still needed to protect both the environment and public health. Pretty cool stuff from right here at CSN.
