Alkalinity is a measure of the acid-neutralizing capacity of water that enables it
to resist abrupt changes in pH. It is the sum of all titratable bases. Alkalinity is
signifi cant in maintaining proper pH levels in natural water; water used for irrigation,
swimming pools, industrial processes and wastewater treatment processes.
The presence of buffering materials in natural waters helps to neutralize acids as
they are added to, or created in, the water ecosystem. A Total Alkalinity of 100 to
200 ppm will stabilize the pH level in a stream. In swimming pools, total alkalinity
is commonly known as a pH stabilizer because, when the alkalinity is at a proper
level, a consistent pH level can be maintained while treatment chemicals or fresh
make-up water is added. In industrial situations, alkalinity is an important factor in
preventing fl uctuating pH levels that can damage equipment and corrode pipes.
