Stettfurt's drinking water ban persists after fecal contamination scare

A drinking water ban remains in place across much of Stettfurt, Thurgau, after fecal bacteria contaminated the local supply. The issue was traced back to polluted stream water from the Lauche stream, which mixed with the drinking water system at a nearby vegetable farm. Residents have been advised to boil tap water before use while investigations continue.

The contamination was first detected after residents reported gastrointestinal problems. Tests confirmed the presence of fecal bacteria in the drinking water, prompting an immediate ban. Authorities later identified the source as Gamper, a large vegetable farm licensed to draw water from the Lauche stream.

The farm used stream water for cleaning outdoor areas and machinery, which led to the contamination of the drinking water network. Since the discovery, over 10,000 litres of bottled water have been distributed to affected households. The farm has now been banned from using stream water, and a separation system will be installed to prevent future incidents.

Ongoing water tests show improving values, but no all-clear has been given yet. Specialists have flushed pipelines and house installations multiple times and adjusted water softening systems. Meanwhile, authorities are still examining how the contamination occurred and who will cover the financial costs.

The drinking water ban in Stettfurt stays in effect as tests and corrective measures continue. Residents must still boil tap water before drinking or cooking. Officials have not yet confirmed when normal water use will resume.
