Overview
- Vitens ended the advisory on January 18 after multiple consecutive measurements showed no enterococci in the drinking-water network.
- About 84,000 connections across Amersfoort and nearby towns were under the three‑minute boiling advisory for roughly thirteen days as it was extended three times.
- The contaminated storage cellar at the Hogeweg production site was taken out of service while the network was cleaned, flushed, and sampled at multiple locations, including households.
- Residents who did not use their taps during the advisory are urged to run water for about one minute to flush household pipes before normal use.
- Enterococci are not normally present in drinking water and can cause gastroenteritis‑like symptoms, posing higher risks for people with weakened immune systems.
