Drinking Water Quality in India: BIS IS 10500 Compliance
India's drinking water quality is governed by BIS IS 10500:2012, which prescribes acceptable and permissible limits for 28 physical, chemical, and bacteriological parameters including turbidity, pH, total dissolved solids, fluoride, arsenic, iron, and coliform bacteria. The Jal Jeevan Mission (JJM) mandates functional household tap connections with water meeting IS 10500 standards for all rural households.
What DrinkSafe Tests
DrinkSafe evaluates water sample data against BIS IS 10500:2012 acceptable limits, CPHEEO Manual on Water Supply standards, FSSAI packaged drinking water requirements, and WHO Guidelines for Drinking-water Quality (4th edition). The 30-point Water Safety Plan (WSP) checklist follows the WHO WSP framework adapted for Indian conditions.
Key Parameters for Indian Conditions
- Fluoride: Acceptable 1.0 mg/L, permissible 1.5 mg/L — endemic fluorosis affects 19 Indian states
- Arsenic: Acceptable 0.01 mg/L — groundwater contamination in West Bengal, Bihar, UP, Assam
- Iron: Acceptable 0.3 mg/L — widespread in eastern and northeastern India
- Total Coliform: Must be absent in 100 mL — primary indicator of faecal contamination
