The Food Safety and Standards Authority of India (FSSAI) has ushered in a transformative regulatory regime for India's packaged water industry by implementing a new mandatory Scheme of Testing for Packaged Drinking Water (PDW) and Mineral Water. The revised framework marks a significant departure from the earlier compliance structure centred around mandatory certification by the Bureau of Indian Standards (BIS). Effective from January 1, 2026, all licensed Food Business Operators (FBOs) engaged in the manufacture and sale of packaged drinking water and mineral water are now required to comply with a rigorous, continuous, science-based testing and monitoring system administered under the Food Safety and Standards Act, 2006.
The regulatory shift originates from FSSAI's Gazette Notification dated October 17, 2024, through which the mandatory BIS certification requirement for packaged drinking water and mineral water was formally withdrawn. This was subsequently operationalized through a detailed enforcement order issued on December 17, 2025, prescribing the new Scheme of Testing and Inspection applicable to all licensed manufacturers across the country. The development represents one of the most significant structural reforms in India's food and beverage regulatory landscape, particularly within the rapidly expanding bottled water industry.
Historically, manufacturers of packaged drinking water and mineral water were required to obtain BIS certification and use the ISI mark as evidence of conformity with prescribed Indian Standards. The BIS model largely relied upon periodic inspections, product sampling, and certification audits conducted under the Bureau of Indian Standards Act and related regulations. While the certification regime established baseline quality standards, concerns were frequently raised regarding uneven compliance, post-certification monitoring gaps, and the limitations of a one-time approval framework in ensuring sustained product safety.
The newly introduced FSSAI testing regime fundamentally changes the compliance philosophy by replacing static certification with continuous, evidence-based regulatory oversight. Under the revised framework, Food Business Operators are no longer merely required to secure initial approval; instead, they must continuously demonstrate product safety through periodic laboratory testing, documented compliance records, process monitoring, and scientific verification. The scheme introduces an ongoing accountability mechanism intended to strengthen traceability, transparency, and consumer protection.
The new testing protocol mandates extensive microbiological, chemical, physical, toxicological, and packaging-related assessments at prescribed intervals through FSSAI-notified and NABL-accredited laboratories. Monthly microbiological testing has been made compulsory for all packaged drinking water and mineral water units. Such testing includes examination for pathogenic organisms and microbial contaminants such as coliform bacteria, E. coli, fecal streptococci, sulphite-reducing anaerobes, Pseudomonas aeruginosa, yeast, mould, and total plate count parameters. The purpose of mandatory monthly microbiological surveillance is to ensure continuous safety monitoring and immediate identification of contamination risks.
The framework further requires quarterly, biannual, or tri-annual testing of chemical and physical parameters depending upon the nature of the constituent being monitored. These include assessments relating to pH levels, turbidity, total dissolved solids, hardness, heavy metals, fluoride, nitrate, arsenic, cyanide, pesticide residues, and toxic contaminants. Manufacturers are also obligated to conduct periodic pesticide residue analysis in order to identify traces of agricultural chemicals that may enter groundwater or source water systems. Such testing requirements are especially relevant in light of increasing industrial pollution, agricultural runoff, and groundwater contamination concerns across several regions of India.
One of the most stringent features of the new framework is the mandatory retesting requirement whenever there is any change in the source of water. Whether due to seasonal variation, depletion of groundwater, infrastructural modifications, or operational shifts, any alteration in the source necessitates fresh testing and verification before production can continue. This reflects FSSAI's emphasis on source-to-bottle traceability and preventive risk management.
The regulations also prescribe an uncompromising 'zero-tolerance' approach toward radioactive contamination. Water samples are required to comply with prescribed limits relating to gross alpha and gross beta radioactivity. Any deviation from the stipulated standards may render the product unsafe under the Food Safety and Standards Act, 2006. This aspect of the framework aligns Indian standards more closely with globally evolving public health norms concerning radiological safety in drinking water.
The microbiological compliance mechanism introduced under the scheme is particularly stringent. In the event of any microbiological non-compliance, the concerned manufacturing unit is required to immediately halt production operations. Resumption of production is permitted only after corrective actions are implemented and multiple consecutive batches are found compliant upon retesting. Such provisions demonstrate the regulator's intention to prioritize public health protection over uninterrupted commercial production.
In addition to water quality testing, the scheme extends regulatory scrutiny to packaging materials used in bottled water manufacturing. Food Business Operators are required to undertake biannual testing of bottles, caps, containers, and packaging materials to ensure conformity with the Food Safety and Standards (Packaging) Regulations, 2018. This requirement recognizes that packaging materials themselves may become sources of chemical migration, contamination, or consumer health hazards if substandard or non-food-grade materials are used.
The revised framework also places significant emphasis on manufacturing hygiene and operational controls. All packaged water units are mandated to strictly comply with Good Manufacturing Practices (GMP), Good Hygienic Practices (GHP), and sanitary requirements prescribed under Schedule IV of the Food Safety and Standards (Licensing and Registration of Food Businesses) Regulations, 2011. Manufacturers are required to maintain detailed records of testing reports, sanitation protocols, water treatment operations, filtration systems, disinfection procedures, source verification records, and corrective action measures. Such documentation must be readily available for inspection by food safety authorities during audits or enforcement proceedings.
Legally, the revised framework derives authority from the Food Safety and Standards Act, 2006, which empowers FSSAI to prescribe standards, regulate food safety systems, and enforce compliance mechanisms for food articles sold within India. Section 16 of the Act entrusts FSSAI with the responsibility of laying down science-based standards and regulating the manufacture, storage, distribution, sale, and import of food to ensure safe and wholesome food for human consumption. The new testing scheme reflects the authority's movement toward dynamic, risk-based regulation rooted in continuous scientific assessment.
The regulatory transition also has substantial implications for Food Business Operators. Unlike the earlier BIS-centric system where certification often served as a long-term compliance marker, the new regime imposes recurring operational responsibilities and increased compliance costs. Manufacturers must now invest in frequent laboratory testing, robust quality assurance systems, documentation infrastructure, process validation mechanisms, and trained technical personnel. Smaller manufacturers, particularly in the unorganized sector, may face operational and financial challenges in adapting to the heightened regulatory expectations.
However, from a public policy perspective, the transition is expected to substantially improve consumer confidence in bottled water products. India's packaged water industry has witnessed exponential growth over the last decade due to urbanization, increasing health awareness, declining trust in municipal water supplies, and rising demand for safe drinking water. Simultaneously, the sector has also faced repeated allegations concerning contamination, fake brands, unauthorized bottling units, misleading labeling, and poor quality control practices. By introducing a continuous testing regime, FSSAI aims to create a more transparent and accountable ecosystem capable of detecting non-compliance in real time rather than relying solely upon periodic certification renewals.
The shift also reflects broader global trends in food regulation. Modern food safety governance increasingly emphasizes preventive controls, traceability, hazard analysis, scientific validation, and ongoing surveillance rather than static licensing models. International regulatory systems such as those adopted in the European Union and several advanced jurisdictions focus heavily on risk-based monitoring and continuous compliance verification. FSSAI's revised framework appears aligned with these evolving global best practices.
The implementation of the new scheme is also likely to strengthen enforcement capabilities. Since manufacturers are required to maintain regular testing records and laboratory reports, enforcement agencies can more effectively identify patterns of non-compliance, recurring contamination events, or fraudulent practices. The framework further enables improved regulatory data collection and facilitates evidence-based policymaking in the packaged water sector.
At the same time, successful implementation will depend significantly upon the capacity of testing laboratories, enforcement personnel, and industry compliance mechanisms. The availability of accredited laboratories, timely sample analysis, uniform interpretation of standards, and effective coordination between Central and State authorities will be critical for ensuring the credibility and effectiveness of the new system. FSSAI may also need to conduct extensive industry outreach and training programs to assist manufacturers in understanding technical obligations under the revised regime.
In conclusion, the implementation of FSSAI's new mandatory Scheme of Testing for Packaged Drinking Water and Mineral Water marks a decisive regulatory transformation in India's food safety architecture. By replacing the traditional BIS certification model with a continuous testing and monitoring framework, the regulator has fundamentally redefined accountability within the bottled water industry. The revised system prioritizes scientific verification, preventive monitoring, source traceability, microbiological vigilance, packaging safety, and sustained operational compliance. While the transition may impose greater compliance burdens on manufacturers, it is ultimately aimed at ensuring higher standards of consumer protection, public health safety, and regulatory transparency in one of India's fastest-growing food sectors.
