Rainwater is no longer potable

August 24, 2022

We've all heard that rain water is the purest. Rainwater, however, is no longer potable, according to research from the University of Stockholm, which was recently published in the journal Environmental Science and Technology. In most parts of the world, the synthetic element PFAS was discovered in rainwater.

What are PFAs?

We have heard numerous times that rainwater is the purest. However, new research from Stockholm University that was just published in the journal Environmental Science and Technology indicates that rainfall is no longer potable. In most regions of the world, rainwater included the synthetic substance PFAS.

PFAs are man-made compounds used to manufacture nonstick cookware, water-repellent clothing, stain-resistant fabrics, cosmetics, firefighting materials, and many other things that resist grease, water, and oil, according to the US Centre for Disease Control and Prevention (CDC). During the course of their production and usage, PFAs can move to the land, water, and air. The majority of PFAs do not degrade, therefore they linger in the environment for a long time. If people and animals are exposed to these PFAs on a regular basis, they may develop an accumulation of the chemicals.

How harmful are PFAs?

PFAS exposure has been linked to a number of negative health outcomes, including cancer, liver damage, lower fertility, as well as an increased risk of asthma and thyroid illness, according to a new analysis from the U.S. Centers for Disease Control and Prevention (CDC). Children frequently drink rainwater and get drenched in the water. They must be made aware of this, after all.

How do these chemicals get out of rainwater?

There is currently no known method for extracting and removing PFAs from the atmosphere. However, there are some effective methods for removing them from rainwater. One method is to absorb it from the atmosphere using a filtration system with activated carbon; however, the activated carbon must be replaced on a regular basis, and the old contaminated material must be destroyed on occasion.
