There is set out highly efficient processes for the production of alkaline spring waters. The processes are designed to minimize the use of the additive alkaline formulations used to create the alkalinity in the spring waters and the use of a maximum amount of non-purified spring water in the formulation of the final alkaline spring water product. This is accomplished by dividing the input spring water into at least two portions. One portion undergoes a purification process and the other is not purified. Each portion is tested in increments for the amount of alkaline formulation needed to attain a pH of at least about 10 and designated potassium ion and sodium ion contents. From the testing the amount of the purified spring water and the amount of non-purified spring water needed to be combined to yield a pH of at least about 10 and the designated potassium ion and the sodium ion contents is calculated. It is desired to use a minimum of alkaline formulation to achieve the set Ph and potassium and sodium ion concentration. In this way the more costly components of the alkaline formulation and the purified spring water can be minimized, but yet the taste and stability maintained over a period of time. The processes apply to waters from a single spring and from a plurality of springs.
