According to the Bureau of Indian Standards (BIS) IS 10500:2012, the acceptable limit for pH of drinking water is 6.5 to 8.5.
pH is a measure of how acidic or basic water is. A pH of 7 is neutral. Values below 7 indicate acidity, and values above 7 indicate alkalinity. Maintaining pH within the acceptable range is important for water potability and preventing corrosion in pipes.
The BIS standard also specifies a permissible limit in the absence of an alternate source, which can extend slightly beyond the acceptable limit, but the primary acceptable range for drinking water quality is 6.5 to 8.5.
