Physico-chemical analysis report

Summary

This report presents the physico-chemical analysis of water for the La Fère Gerontologique center heating system. Measured parameters include pH, conductivity, chlorides, TAC, TH, SiO2, PO4^3-, MoO4^2-, Fe, Cu, Al and Zn. Results show pH 7.95, conductivity 692 µS/cm, chlorides 39.1 mg/L, TAC 33.37, TH 37, SiO2 1.8 mg/L, PO4^3- 0 mg/L, MoO4^2- 0 mg/L, Fe total 0 mg/L, Cu total 0 mg/L, Al total 0 mg/L and Zn total 0.21 mg/L. Recommendations: based on TH, install a softening unit. Analyses performed after filtration through 0.45 µm or mineralization. Lab stamp: 21 Apr 2026.
