Alkalinity of surface water, quantified by mg/L as CaCO 3 or meq/L, may be caused by carbonates, bicarbonates, hydroxides, phosphates, borates, silicates, or organic acid salts. Conventionally, the water alkalinity is approximated as sum of components. Three types of alkalinities exist together to form total alkalinity (TA): TA = OH-+ CO 3 2-+ HCO 3-
