Understanding Water Alkalinity
Becoming one of the popular health trends, there is a big chance you might have heard about alkaline water. Coming from basic science, most of us know that on the opposite spectrum of acidity is alkalinity.
Alkalinity is defined as “the buffering capacity of a water body or the measure of the ability of a water body to neutralize acids and bases and thus maintain and fairly stable pH level.” In simpler terms, it is a measurement of a water’s ability to neutralize acids. If water’s neutral state is at 7, anything lower than that is acidic, while anything higher than that is alkaline.
Importance of Alkalinity
Alkalinity is useful in the health of a lake as the lake ecosystem as aquatic organisms benefit from stable pH values. In today’s society where bodies of water can experience sudden input of contamination such as chemicals and wastewater, it can disrupt the acid/base balance present which can lower the pH of the bodies of water. The same thing occurs during acid shock when acid rain, acidic dryfalls, and discharges of tanning water happens and comes into contact with the water. High alkaline in water can act as a great buffer to counter when these acidic discharges enter the body of water. This is why having high alkalinity is important in maintaining a relatively constant pH.
What Causes Alkalinity?
Bicarbonates are the major form of alkalinity in natural waters; coming from the carbon dioxide from the atmosphere coupled with the weathering of carbonate minerals like rock and soil. In the example of the lake, alkalinity is caused by the rocks and land surrounding the body of water. Here, precipitation lands on the rocks that surround the lake and picks up its minerals before it goes to the water which increases the alkaline level. If this landscape is an area that is abundant in limestone which contains chemicals such as calcium carbonate (CaCO3), the alkalinity of the water rises, whereas areas containing granite in large amounts can lower the alkalinity.
How is it Measured?
Alkaline is measured using a process called titration. This is when an initial pH reading is taken then small amounts of acid is added incrementally, the water is stirred, then the pH is taken again. This is a process done many times until the compounds found in water such as bicarbonates, can no longer neutralize the acids. Once it reaches this equivalence point, all further acid added will then lower the pH level.
Alkaline Drinking Water
Alkaline water that we consume for drinking comes from water filtration systems. These household water filtration systems do not only work to remove contaminants in the water like fluoride, chlorine, and many other toxic metals, but they can also make the water more alkaline in itself. These types of filters include mineral balls to achieve this. For your water filtration and alkaline needs, you can always turn to Megafresh, your trusted water system provider.
