WATER QUALITY TESTING

Even though water may be clear, it does not necessarily mean that it is safe for health. It is important to judge the safety of water by taking the following qualities into consideration

Physical & Chemical Properties :

- Appearance

- Turbidity (NTU)

- pH (at 25 C) *

- Conductivity (µS/cm) at 25 C *

- Total Dissolved Solids (ppm as NaCl)

- Total Hardness (ppm as CaCO3)

- Ca-Hardness (ppm as CaCO3)

- Mg-Hardness (ppm as CaCO3)

- M-Alkalinity (ppm as CaCO3)

- P-Alkalinity (ppm as CaCO3)

- Bicarbonate (ppm as CaCO3)

- Total Iron (ppm as Fe)

- Chloride (ppm as Cl)

- Residual Chlorine (ppm as Cl2) at site checking

REMARK
