WebAlkalinity and water hardness are fairly similar--essentially they both come from sources in nature. Water moves through rocks (and picks up minerals as it does so) on its way to rivers and lakes. When limestone and dolomite dissolve in water, one half of the molecule is calcium or magnesium (the "hardness") and the other half is the carbonate ... WebWaters with low alkalinity are very sensitive to changes in pH; as alkalinity increases the ability of water to resist pH changes grows, enlarging its buffering capacity. The buffering bases are primarily the bicarbonate (HCO 3 − ) and carbonate (CO 3 2 − ), and alkalinity is generally expressed as the equivalent calcium carbonate concentration (CaCO 3 ).
