  Aims. Lack of chemical quality control of drinking-water (DW) in distribution systems may cause corrosion, precipitation and ultimately leads to economics and health damages. The goal of this study was to evaluate the chemical quality of DW in military centers and predict the potential of corrosion and precipitation within those DWs.

  Methods. In this cross-sectional and descriptive study the chemical quality of DW (underground) in 9 military centers located in different water basin of Iran were investigated in four different seasons. In any season, 3 grab samples with 2-3L of water volume have been obtained. All of the samples were collected, stored and preserved in glass or polyethylene container and analyzed based on standard methods. The potential of corrosion and precipitation of DWs were calculated by Langelier saturation Index (LSI), Aggressive Index (AI) and Risnar Index (RI).

  Results. Based on the calculated values of indices, DW of G3, G4 and G5 centers had shown corrosive properties, but other centers showed precipitated properties. Based on LSI, AI and RI the DW of all centers showed a uniform quality of corrosion and precipitation potential.

  Conclusion. Monitoring of chemical quality, precipitation, corrosion potential and concentration of heavy metals should be considered in DW quality control programs .
