Introduction
Bottled water in India has shifted from occasional convenience to daily necessity due to declining trust in municipal water and belief in plastic-sealed safety. It is generally microbiologically safe, but scientific evidence now highlights risks from microplastics and plastic-derived chemicals. These invisible contaminants raise concerns about long-term health, environmental sustainability, and regulatory gaps. Bottled water remains essential in emergencies and areas lacking safe public supply, but growing dependence has created new safety and governance challenges.
Major Concerns Related to Bottled Water in India
- Microplastic contamination: Microplastics, plastic particles smaller than five millimetres, are found in bottled water, making it a direct exposure source. A Nagpur study detected 72 to 212 particles per litre in all tested brands, with higher levels in locally bottled water.
- Widespread presence: Studies from Mumbai and coastal Andhra Pradesh found microplastics in every tested sample. This confirms contamination across regions, brands, and supply chains.
- Health risk uncertainty: Microplastics carry toxic additives and pollutants, and smaller particles may cross biological barriers. Nanoplastics remain outside detection and regulation, increasing long-term safety concerns.
- Chemical leaching: Plastic bottles release antimony, phthalates, and plasticisers, especially when exposed to heat and sunlight. Such exposure commonly occurs during transport, storage, and retail display.
- Long-term exposure gap: Chemicals remain within limits, but standards assess short-term exposure to individual substances. They do not address combined and long-term exposure to multiple plastic-derived contaminants.
- Environmental contamination: India generates millions of tonnes of plastic waste annually, with water bottles forming a major share. Plastic waste breaks into microplastics, contaminating ecosystems and water sources, including bottled water.
Factors Responsible for Bottled Water Safety Concerns in India
- Trust deficit: Declining trust in municipal water safety has increased dependence on bottled water. People consider plastic-sealed water safer than public supply.
- Regulatory limitations: Existing regulations under FSSAI do not include testing or limits for microplastics. They also do not adequately assess long-term exposure to plastic-derived chemicals under real storage and usage conditions.
- Weak enforcement gaps: State-level surveys, including those in Karnataka, have found bottled water samples that are unsafe or substandard. This shows gaps in enforcement rather than absence of regulations.
- Fragmented bottling structure: The industry consists of thousands of small bottling units operating with minimal oversight. This creates uneven quality control and increases the risk of contamination.
- Heat exposure: Bottles are frequently exposed to heat and sunlight during transportation, warehousing, and retail display. Elevated temperature and ultraviolet exposure increase chemical leaching from plastic into water.
- Plastic waste cycle: India generates large amounts of plastic waste, and discarded bottles break into microplastics. These particles re-enter ecosystems and water sources, contributing to contamination of bottled water supplies.
Way forward
- Regulatory reforms: Safety standards should include routine testing and limits for microplastics and plastic-derived chemicals, which are currently not covered. This will ensure monitoring reflects real exposure risks under actual storage and usage conditions.
- Strengthening public water system: Improving municipal water supply and ensuring transparent public disclosure of water quality can rebuild trust in monitored public systems. This will reduce excessive dependence on bottled water as a default choice.
- Safe usage practices: Point-of-use filtration can help remove particulate contaminants present in water. Avoiding prolonged storage and heat exposure can reduce chemical leaching from plastic bottles.
- Alternative safer water access: Increasing access to refill stations, public water dispensing systems, and affordable household filtration can provide reliable alternatives. This will reduce reliance on single-use bottled water.
- Consumer awareness: Improving awareness about contamination risks and safe handling practices can help people make informed choices. This can encourage reduced dependence on bottled water where safe alternatives exist.
Conclusion
Bottled water in India is microbiologically safe but faces risks from microplastics, chemical leaching, and regulatory gaps. These arise due to weak regulation, plastic waste, poor storage, and declining trust in public water. Ensuring safe drinking water requires stronger regulations, better enforcement, improved municipal supply, and reduced dependence on plastic bottles, supported by accountable and transparent public water systems.
