Interactive Water-Quality Map Flags Lot‑et‑Garonne in Red — Local Managers Call CVM Exceedance Isolated

The red zones reflect results tied to a single tap or small antenna rather than entire public supplies.

Overview

  • Published on October 16, the Générations Futures and Data For Good map compiles ARS data by UDI and shows two Lot‑et‑Garonne sectors in red due to chlorure de vinyle monomère (CVM).
  • Syndicat Eau 47 says a June 25 ARS non‑conformity came from a network antenna serving one subscriber and was mistakenly linked to the main Saint‑Pierre supply, with the user notified and mitigations started.
  • In the Agen area, officials report one household is concerned, potable water is being provided, and corrective works are ordered for December.
  • Remediation is advancing with purges where feasible, bottled water when not, 21 kilometers of pipes already replaced in the Agen agglomeration, another five kilometers planned next year, and Eau 17 budgeting €1.3 million in 2025 and €2 million in 2026.
  • Générations Futures plans improvements to the tool to reduce misleading area classifications, as experts emphasize that over 87% of UDIs comply and that tap water carries a generally low health risk.
