Qui pollue notre eau du robinet ?

Hugo Clément investigated tap‑water pollution and remediation in France. When drinking water exceeds contamination limits, authorities simply blend it with a purer source and pump it back into the network. The probe also shows that tap water is increasingly tainted by pesticide residues, industrial pollutants, and even remnants of warfare, driving up treatment costs. Some citizens are campaigning to curb upstream sources of contamination rather than continually funding ever‑more expensive treatment plants.
