focusing on purity (no pathogens), consistent mineral composition (pH 6.5-8.5, specific limits for metals like arsenic, lead), physical parameters (TDS, clarity), food-grade packaging (PET/glass), and certifications like ISO 22000, HACCP

food-grade, sterile, tamper-proof materials (like PET) that don't leach chemicals, with robust outer cartons for transport, and accurate labeling detailing water source, composition (pH, TDS), batch, dates, and importer info
