10500:2012) specifications in Uniform Drinking Water Quality Monitoring Protocol, what is
the acceptable pH value of drinking water specification in India?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 6.5 - 8.5
- According to the Central Ground Water Board, BIS (IS_10500 and revised module IS 10500:2012) specifications in Uniform Drinking Water Quality Monitoring Protocol, the acceptable pH value of drinking water specification in India is 6.5-8.5.
-
This standard has two limits i.e. acceptable limits and permissible limits in the absence of an alternate source. If any parameter exceeds the limit, the water is considered unfit for human consumption.
-
In broad terms, if the water is bacteriology contaminated (E-coli and viruses etc), or if chemical contamination exceeds maximum permissible limits, the BIS considers that water unfit for drinking.
