WebModerate alkalinity is desirable in most water supplies. Strong alkaline water has an unpleasant “soda” taste. The EPA Secondary Drinking Water Regulations limit alkalinity only in terms of total dissolved solids (500 ppm) and to some extent by the limitation on pH. Webalkalinity (less than 150 mg/L) is more likely to be corrosive. High alkalinity water (greater than 150 mg/L) may contribute to scaling. Acceptable results: This is a test for overall water quality. There are no health concerns related to alkalinity. The value should be roughly 75% to 100% of the total hardness value in an unsoftened sample.

Ensure the total alkalinity is less than 140 ppm, the pH is less than 7.4, and the calcium hardness level is below 350 ppm before addition. DO NOT exceed a 50 ppm borate level in swimming pools.
Alkalinity is frequently given as molar equivalents per liter or kilogram of solution. In commercial (e.g. the swimming pool industry) and regulatory contexts, alkalinity might also be given in parts per million of equivalent calcium carbonate (ppm CaCO 3) [citation needed]. Alkalinity is sometimes incorrectly used … See more Alkalinity (from Arabic: القلوي, romanized: al-qaly, lit. 'ashes of the saltwort') is the capacity of water to resist acidification.
