Contamination of Sea Foam with PFAS Detected on German Beaches

Tue 4th Feb, 2025

Recent tests conducted by environmental organization Greenpeace have revealed concerning levels of per- and polyfluoroalkyl substances (PFAS) in sea foam along several German coastlines. Samples collected from beaches on the East Frisian island of Norderney, the island of Sylt in Schleswig-Holstein, and locations such as Sankt Peter-Ording, Boltenhagen, and Kühlungsborn in Mecklenburg-Vorpommern showed significant contamination.

PFAS are a group of synthetic chemicals known for their water- and grease-repellent properties and stability, making them prevalent in various industrial applications and consumer products. Unfortunately, these substances are not easily degradable and have been found to permeate the environment, including water sources, soil, and food. The potential health implications are severe, with studies suggesting a link between PFAS exposure and cancer.

The concentrations of PFAS detected in the analyzed sea foam samples were alarming, with findings comparable to previous research conducted in the Netherlands, Denmark, and Belgium. Greenpeace reported that out of 31 PFAS compounds tested, 14 were identified in the samples, with the highest concentration recorded in an older foam sample from Kühlungsborn at approximately 160,000 nanograms per liter. In contrast, more recent foam samples from the surf at Sylt still showed significant levels, around 96,000 nanograms per liter.

To put these figures into context, Denmark has established a threshold for bathing water at 40 nanograms per liter. The PFAS levels found in German samples exceeded this limit by 290 to 3,777 times. Alarmingly, German authorities have yet to set any regulatory standards for PFAS contamination in sea water or foam, leaving public health and safety concerns unaddressed.

Environmental advocates have criticized the lack of action from German officials in managing the risks associated with these persistent chemicals. In contrast, authorities in Denmark and the Netherlands have actively issued warnings about the dangers of contact with contaminated sea foam and provided guidance on how to decontaminate oneself after beach visits. In Germany, however, official testing for PFAS contamination in sea foam remains nonexistent.
