Swimming water around Amsterdam contains high concentrations of chemical substances
Recent research shows that the swimming water in and around Amsterdam is polluted with chemical substances in many places. These substances, known as PFAS, end up in surface water through industry and consumer products. The concentrations at some locations are higher than the advisory values recommended by experts.
The province and the water boards are closely monitoring water quality. Although the presence of these substances is worrying for the environment, experts emphasize that an occasional dip in the water does not pose an immediate danger to most people. The risk arises primarily from long-term exposure, for example by swallowing large amounts of water or eating fish from polluted ditches.
Nevertheless, the authorities advise swimmers to be cautious. It is important to always shower well after swimming in natural water and to avoid swallowing water. Especially for small children and people with weaker health, it is wise to only swim at official locations where water quality is regularly checked.
The municipality of Amsterdam and the surrounding water boards are working together to tackle the sources of the pollution. This is a complex process because PFAS substances are very persistent and do not simply disappear from the water. Research is currently being conducted into what long-term measures are needed to make the swimming water safer for residents again.
For the time being, the advice remains to consult the website 'zwemwater.nl' before setting off. This site indicates per location whether it is safe to swim. This way, swimmers in the Amsterdam region can responsibly enjoy the summer weather without running unnecessary health risks.
