Water purification - Wikipedia
Water purification - Wikipedia

Fresh water can have widely ranging pH values depending on the geology of the drainage basin or aquifer and the influence of contaminant inputs ( acid rain ). If the water is acidic (lower than 7), lime, soda ash, or, sodium hydroxide, can be added to raise the pH during water purification processes.
