In recent months, reports of the contamination of our drinking water with so-called “forever chemicals” such as trifluoroacetic acid (TFA) and PFAS (per- and polyfluoroalkyl substances) have caused a stir. We have reported on this several times under the PFAS section<\/a>. These substances are particularly concerning because they are extremely persistent and can accumulate in the environment and in the human body.<\/p>\n<\/div>

What are PFAS and TFA?<\/h2><\/div>

PFAS is a group of over 4,700 industrially produced chemicals used in numerous everyday products such as pans, textiles, cosmetics, and firefighting foams. They are known for their water, grease, and dirt-repellent properties. TFA (trifluoroacetic acid) is a particularly short-chain PFAS and is often formed as a degradation product of other fluorine-containing chemicals, particularly pesticides and refrigerants. Due to their chemical stability, both PFAS and TFA are extremely persistent and are therefore often referred to as “forever chemicals.”<\/p>\n<\/div>

How do these substances get into drinking water?<\/h2><\/div>

TFA and other PFAS enter our environment through various routes:<\/p>\n
