Alkalinity
Alkalinity of natural waters is due primarily to the presence of weak acid salts although strong bases may also contribute (i e OH-) in extreme environments |
Measuring alkalinity is important to determining a river's ability to neutralize acidic pollution (as measured by pH) from rainfall or snowmelt.
It's one of the best measures of the sensitivity of the river to acid inputs.
What is alkalinity due to?
Alkalinity of natural waters is due primarily to the presence of weak acid salts although strong bases may also contribute (i.e.
OH-) in extreme environments.
What changes the alkalinity of water?
What affects alkalinity? Total alkalinity is affected by environmental factors; rain, acidic sanitizers, addition of fill water and other product applications can all change the alkalinity over time.
Most alkalinity in surface water comes from calcium carbonate, CaCO3, being leached from rocks and soil.
What causes alkalinity in water?
Local geology and the acidity of soils and rocks have a big influence on the alkalinity of water.
When water passes through soils and rocks that have a high carbonate mineral concentration, water accumulates carbonates and becomes more alkaline.
Sedimentary and limestone rocks also increase water's alkalinity.14 sept. 2022
