Boil Water Advisory for Dordrecht, Zwijndrecht, and Hendrik-Ido-Ambacht Due to E. Coli

The Veiligheidsregio Zuid-Holland Zuid issued a boil water advisory for Dordrecht, Zwijndrecht, and Hendrik-Ido-Ambacht on June 12, 2026, after E. coli bacteria were detected in the drinking water. Residents must boil tap water for at least three minutes before using it for drinking, cooking, or brushing teeth for the next 72 hours.

How should residents treat their water?

Residents must boil tap water for a minimum of three minutes, according to the Veiligheidsregio Zuid-Holland Zuid. This process eliminates bacteria that may have entered the piping network.

The safety region recommends using a pan or a whistling kettle. They warn that coffee makers and electric water kettles typically do not boil water for three consecutive minutes. Residents should check their appliance manuals to verify boiling times.

Did You Know? The Veiligheidsregio Zuid-Holland Zuid specifically warns against relying on standard electric kettles and coffee machines because they often fail to maintain a boil for the required three minutes.

Why is the boil advisory in effect?

The advisory follows the detection of E. coli bacteria during drinking water checks in Dordrecht, Zwijndrecht, and Hendrik-Ido-Ambacht. The Veiligheidsregio Zuid-Holland Zuid announced the finding via Facebook.

The measure aims to protect residents from contaminated water. The advisory remains in effect until research confirms that the tap water in these three areas is fully reliable.

Expert Insight: Samantha Carter notes that the requirement for a sustained three-minute boil indicates a necessity for complete thermal eradication of E. coli within the domestic piping network to ensure consumer safety.

What happens next?

The current advisory is set for a 72-hour window. A possible next step involves the publication of research results to determine if the water is safe for consumption.
