Overview
- Testing found a light enterococci contamination in a storage facility on Utrechtseweg and earlier in the Randenbroek network, and the source remains unknown.
- The advisory covers postcode areas 3814–3819 in southern Amersfoort, where residents must boil tap water for three minutes for drinking, food preparation and toothbrushing.
- Showering and handwashing are allowed, and water service continues while Vitens flushes mains and takes additional samples in the isolated supply area.
- Vitens says two clean results in a row are required before declaring the water safe, and results take roughly 48 hours per round of testing.
- Local shops report runs on bottled water and institutions such as hotels, restaurants and care homes have put contingency measures in place, with the Vitens postcode checker designated as the authoritative guide for who is affected.
