What the RIVM measures in Dutch tap water

Water is on the table all day. Tap water meets the law, but in tap water made from river and lake water the RIVM often measures more PFAS than its own advisory value.

What the RIVM measures

PFAS barely break down in nature. They are found in river and lake water, among other places, which some water companies use to make tap water.

259 of 454 measurements in tap water from river and lake water were above the RIVM advisory valueRIVM advisory value 4.4 ng/l · measurements 2015 to February 2021 · RIVM letter report 2022-0149

If your tap water comes from groundwater, the picture is different: there, 27 of 273 measurements were above the advisory value.

Advisory value and legal limit

Two methods: the advisory value weights substances by toxicity, the limit adds up 20 PFAS. Dutch drinking water meets the legal limit.

Where does your tap water come from?

That depends on your water company: river and lake water, groundwater or a mix.
