Overview
- About 15,000 households were affected across Leusderkwartier, Bergkwartier, Vermeerkwartier and Randenbroek, with a small number in Soesterberg.
- The advisory began on December 24 in Randenbroek after enterococci were detected, and residents were told to boil water for three minutes.
- It was expanded on Saturday when contamination was also found in the treated-water reservoir on Utrechtseweg.
- Enterococci typically pose little risk to healthy people but can be problematic for those with weakened immune systems.
- The precaution disrupted holiday routines, prompting bottled-water purchases and operational changes at the local zoo, a hotel and a care home.
