Alkalinity is the name given to the quantitative capacity of an aqueous solution to neutralize an acid. Measuring alkalinity is important in determining a stream's ability to neutralize acidic pollution from rainfall or wastewater. It is one of the best measures of the sensitivity of the stream to acid inputs. There can be long-term changes in the alkalinity of streams and rivers in response to human disturbances.

Alkalinity is related to the pH of a solution, (its basicity) but measures a different property. Roughly, the alkalinity of a solution is a measure of how "strong" the bases are in a solution, whereas the pH measures the "amount" of chemical bases. A good example is a buffer solution, which can have many available bases (high alkalinity) despite having only a moderate pH level.
