An acceptable pH range for drinking water is from 6.5 to 8.5. Corrosion effects may become significant below 6.5, and the frequency of incrustation and scaling problems may be increased above pH 8.5. High pH levels decrease the efficiency of chlorine disinfection processes. The pH reported is at room temperature. Conductance is an indication of dissolved salts in the water.
Hard waters have a tendency to form scale deposits in pipes and heating coils.
Hardness may be inversely related to the incidence of cardiovascular disease. Because water softening by sodium exchange may introduce undesirably high quantities of sodium into drinking water, it is recommended that where such a process is employed, a separate unsoftened supply be retained for drinking and culinary purposes.
