What is Water Report?
A water analysis (potability) report certifies that the water used in food preparation or as an ingredient meets drinking-water standards, i.e. potable water as per BIS IS 10500. It covers chemical and bacteriological parameters. For packaged drinking or mineral water units, the licence application also needs a pesticide residue report of the source water and, for ground-water extraction, a CGWA NOC.
The FoSCoS sample document says reports should be from a ‘recognized/public health laboratory’, while a private compliance guide says only NABL-accredited labs are accepted, so using an NABL-accredited or FSSAI-notified lab is the safe choice. One source says reports should be recent, not older than six months.
