A new study says that changing guidelines for forever chemicals have made rainwater all around the world unsafe to drink
suggests that rainwater is now unsafe to drink. The study says that “forever chemicals” have reached unsafe levels. These forever chemicals are scientifically known as per- and poly-fluoroalkyl substances , and they don’t break down in the environment.You can find PFAS chemicals in non-stick and stain-repellent properties. As such, they’re found in a lot of household food packages, electronics, and even cosmetics and cookware.
It’s an interesting dilemma because rainwater does play such a large role in the water ecosystem for some countries. Perhaps one of the most concerning chemicals, though, is perfluorooctanoic acid . This forever chemical is known to cause cancer, and its guideline values have declined by 37.5 million times in the United States.Because the value guidelines for PFOA in rainwater have changed so much, the current levels leave rainwater everywhere unsafe to drink.
Luckily, we’re already seeing some great work in that field, with some engineers even creating a filtration. If we could take similar tech and filter out harmful chemicals, we could more broadly deploy safe water systems to other countries that rely on rainwater.
