A Ground water was anaylzed as follows; Co2= 30 mg/L as CaCO3
Ca2+= 180 mg/L as CaCO3
Mg+2= 120 mg/L as CaCO3
Na+= 80 mg/L as CaCO3
Alkalinity = 360 mg/L as CaCO3
SO42- = 10 mg/L as CaCO3
Cl- = 10 mg/L as CaCO3
pH = 7.2
Would softening be recommended for this water? Determine the following quantities (as mg/L of CaCO3): Total hardness, calcium hardness (both carbonate hardness [CH] and non-carbonate hardness[NCH]), and magnesium hardness (both CH and NCH)
