Context: The Bureau of Indian Standards (BIS) has submitted its report to the Supreme Court of India on drinking water standards in Delhi.
- None of the drinking water samples randomly collected from across Delhi conforms to the ISO standards of purity in one or more requirements.
- All the drinking water samples drawn from Delhi were non-conforming in one or more requirements as per IS 10500:2012 [specification for drinking water].
- One of the main reasons for contamination in Delhi was leaking pipes.
On January 13, the court ordered the pollution control board and the BIS to conduct a random check of water quality in Delhi and submit a report in a month.
The court has asked the BIS to suggest measures to improve water purity and asked it for reports on the samples taken from the other cities.
