Red alert: PFAS in every tested drinking water from Lower Saxony!
In Lower Saxony, PFAS were found in all drinking water samples tested. New limits will apply from 2026.
Red alert: PFAS in every tested drinking water from Lower Saxony!
An alarming report by the environmental protection organization BUND reveals that PFAS were detected in all drinking water samples tested in Lower Saxony. These per- and polyfluorinated alkyl substances are considered harmful to health and are suspected of causing serious illnesses such as liver damage and kidney and testicular cancer. The result relates to tests carried out between June and October 2025, with PFAS being detected in 42 samples of 46 drinking water samples nationwide. What is particularly worrying is the fact that all eight samples from Lower Saxony were contaminated. NDR reports that in some samples the values are even above the future limit values, which should be available from 2026 to 2028.
PFAS are commonly used in water-repellent jackets, non-stick pan coatings, and cosmetic products. These chemicals are extremely long-lasting and are therefore often referred to as “forever chemicals”. According to the EPA, many of these substances are found not only in drinking water, but also in air, soil and even living things, adding to the environmental group's concerns. EPA highlights that exposure to certain PFAS may be associated with adverse health effects in humans and animals.
Limits and challenges
It is important to note that current methods for removing PFAS from water are expensive and resource intensive. The BUND is therefore calling for an immediate phase-out of the production and use of these substances in the EU. According to current information, PFAS can be detected in more than 1,500 locations in Germany. In addition, fewer than 20 of the more than 10,000 known PFAS are regulated, which further exacerbates the problem. To protect public health, it is critical that communities identify and hold accountable those responsible for PFAS.
There are already signs of improvements in regulation. There is discussion at EU level about restricting the entire PFAS group. This could lead to stricter measures to protect drinking water and ensure the health of citizens.
A call to action
Given the serious risks associated with PFAS, action is needed. The BUND studies are local and limited in time, but they only reflect part of the problems. Given the results of these tests, it is clear that it is high time to address this issue effectively. The relevant authorities are called upon to take the test results seriously and take measures to reduce PFAS contamination in drinking water supplies.
BUND and other environmental organizations have a responsibility to educate the public about the risks and increase the pressure on political decision-makers. Sustainable protection of drinking water is only possible if we work together.
