Total Alkalinity: - The alkalinity of water is its capacity to neutralize acids. The maximum
alkalinity was recorded as 516 ppm at station 6 and minimum value is recorded as 154 at station
10. BIS has set a desirable level of alkalinity in drinking water to be 200 ppm where as its value
has been prescribed to be 600 ppm in the absence of alternative source. So in maximum stations
value of total alkalinity present in water is higher
