First of all what is pH?
pH is a measure of the acidity or basicity of a solution
Pure water is said to be neutral, with a pH close to 7.0 at 25 °C

What affects water pH?
Local geology Soil conditions Surrounding vegetation
Mining activities
Industry runoff/water pollution
Other human activities near water body
PH of rainwater and up-wind air pollution sources

In general, water with a pH lower than 7 is considered acidic, and with a pH greater than 7, basic. The normal range for pH in surface water systems is 6.5 to 8.5 and for groundwater systems 6 to 8.5. Alkalinity is a measure of the capacity of the water to resist a change in pH that would tend to make the water more acidic.
