evaluation of water quality of a given place, the water sample was collected and laboratory analysis
was made. By which the following constituents were found. Ca = 50 mg/l; Mg = 15 mg/l; Na = 80 mg/l;
CO3 = 20 mg/l, and HCO3 = 245 mg/. Determine, following parameters:

b. Residual Sodium Carbonate (RSC)
c. Soluble Sodium Percentage (SSP)
d. Magnesium Hazard (MH)
e. Permeability Index (PI) (20 marks)
