Measuring total alkalinity of a water sample can be done with a bromocresol green indicator, which changes from blue to yellow when acid is added. This video describes the method briefly, but more importantly, describes the chemistry behind the method. The most common units for reporting alkalinity of water samples is mg/L (or ppm) as CaCO3. This video describes how to arrive at those units from the titration results.
