Alkalinity is an important parameter for control and treatment of potable water and wastewater because it indicates the buffering capacity of water,  or the ability to resist a pH change. The ability to resist large swings in pH results primarily from the presence of bicarbonates and carbonates. A low water alkalinity signifies that the water is susceptible to pH change,  while a high alkalinity indicates that water is able to resist a major change of pH.\u003c\/p\u003e\n\u003cp\u003eAlkalinity can be used to estimate levels of hardness or to determine the corrosive capacity of water. Alkalinity of surface water,  quantified by mg\/L as CaCO\u003csub\u003e3\u003c\/sub\u003eor 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):\u003c\/p\u003e\n\u003ch5\u003eTA = OH\u003csup\u003e-\u003c\/sup\u003e + CO\u003csub\u003e3\u003c\/sub\u003e\u003csup\u003e2-\u003c\/sup\u003e + HCO\u003csub\u003e3\u003c\/sub\u003e\u003csup\u003e-\u003c\/sup\u003e\n\u003c\/h5\u003e\n\u003cp\u003eOH\u003csup\u003e-\u003c\/sup\u003e = hydroxide alkalinity\u003c\/p\u003e\n\u003cp\u003eCO\u003csub\u003e3\u003c\/sub\u003e\u003csup\u003e2-\u003c\/sup\u003e = carbonate alkalinity\u003c\/p\u003e\n\u003cp\u003eHCO\u003csub\u003e3\u003c\/sub\u003e\u003csup\u003e-\u003c\/sup\u003e = bicarbonate alkalinity\u003c\/p\u003e\n\u003cp\u003eTA = total alkalinity\u003c\/p\u003e\n\u003cp\u003eDifferent tests can be performed to determine the quantity of different alkalinities present.
