Dietikon's Tap Water Passes Rigorous Safety and Quality Tests

**Dietikon**

173 samples confirm: Dietikon's tap water meets all chemical and bacteriological standards, with PFAS levels well below the legal limit—supply remains safe.

According to a statement from the city of Dietikon, the local water utility collected 173 water samples from across the municipal network this year to verify drinking water quality.

The results are reassuring: Every sample met the chemical and bacteriological requirements set by food safety regulations. Additionally, all PFAS (per- and polyfluoroalkyl substances) readings fell below the permissible threshold.

The investigation also examined groundwater extraction sites at Langacker and Russacker (operated by Dietikon's water utility) as well as Schönenwerd 2 (managed by the Limmattal Water Association) for breakdown products of the pesticide chlorothalonil sulfonic acid. These three sources supply drinking water to five municipalities.

Analysis revealed that all twelve samples contained concentrations below 0.01 micrograms per liter—well under the 0.1 microgram-per-liter limit—meaning no harmful residues were detected.

Dietikon's Water: From Ground and Spring

Dietikon's drinking water is sourced from three groundwater pumping stations (Langacker, Russacker, and Schönenwerd 2), with an additional five percent drawn from a spring in Röhrenmoos. Before entering the supply network, the spring water undergoes UV treatment.

Annual tap water consumption in Dietikon totals 2,741,032 cubic meters, fully covered by the groundwater stations and spring source.

As a designated *Blue Community*, Dietikon actively champions water quality and sustainability.
