Hydrionis is an evidence-led water intelligence resource. Every figure carries its source, its method and its licence. Where Hydrionis does not hold a value, it says so rather than estimating one.

Hydrionis presents scientific and regulatory information for general reference. It is not medical, legal or engineering advice. Drinking water standards are jurisdictional: a limit applies only where it was made. For a concern about the water at your own property, contact your water supplier or the relevant regulator.

Data is drawn from public and open sources under their respective licences. Contains public sector information licensed under the Open Government Licence v3.0. Contains modified Copernicus service information. Country outlines derived from Natural Earth (public domain).
