In June, the Danish Environmental Protection Agency announced that drinking water must not contain more than maximum two nanograms per litre of the total sum of the following four PFAS substances: PFOA, PFOS, PFNA and PFHxS.
The restrictions are based on a recommendation from the European Food Agency, EFSA, for tolerable levels of the four substances and an overall quality criterion for the total sum of the substances.
In the fall of 2020, a wastewater contamination with high concentrations of PFOS caused alarm in Denmark and concern about contamination of drinking water. The pollution originated from a fire extinguishing liquid used at a fire school but turned out not to impact drinking water as this is not recovered in the area.
About PFAS
PFAS (per- and polyfluorinated alkyl substances) is the common name for synthetically produced chemicals. More than 4,700 PFAS substances have been identified, all of which are very persistent in the environment, and some are also suspected of being immunotoxic and carcinogenic.
