Some interesting fact to consider since you are talking about rivers: If you know that your water source is surface water then the alkalinity is almost always below 50 ppm. This is because ~50 ppm is the amount of CaCO3 that can stay in solution in water that is at equilibrium with the atmospheric CO2 content. Only when your water comes from a well or has very low calcium content can there be a higher alkalinity.
