Water is life’s elixir, yet a startling 97% of it on Earth is undrinkable seawater. Of the 2.7% that is freshwater, only a fraction is accessible, making it an increasingly precious resource. As the global population explodes, bottled water has become a staple of convenience and safety. However, the “expiration date” on these bottles often raises questions.
Can water actually expire, or is it a marketing gimmick?
Unpacking The Mystery
Water itself is chemically stable and does not spoil. It is the purest, most enduring compound on Earth. However, when bottled, water is influenced by its packaging and storage. According to studies, bottled water can be safely consumed if stored in cool, dark conditions for up to six months. Beyond this, carbonated water may lose its fizz, affecting taste but not safety.
This expiration label on bottled water isn’t about water turning bad but is a mandate for consumer safety. It often serves as a marker to ensure the bottle’s integrity remains uncompromised. For instance, research conducted in the UK revealed that water stored in bottles in extreme heat developed bacterial growth and strange odours after prolonged exposure.
The Real Villain In The Expiry Tale
Most bottled water is stored in PET (Polyethylene Terephthalate) plastic bottles. These bottles are lightweight, cost-effective, and recyclable but come with risks. When exposed to sunlight or heat, PET bottles can leach chemicals like Bisphenol A (BPA) and Phthalates into the water. A study in the Journal of Environmental Science found traces of microplastics in 93% of bottled water samples tested globally.
The expiration date on bottled water often reflects the bottle’s degradation timeline. Improperly stored bottles, such as those left in hot cars, pose an increased risk of contamination. For instance, in a widely reported case, water bottles stored under extreme heat during a recall in 2023 were found to contain unsafe levels of bacteria, emphasising the need for proper storage.
Bottled Water In India
India’s bottled water market is thriving, valued at ₹54,000 crore in 2023 and expected to grow at a CAGR of 20% in the next decade. Brands like Bisleri, Kinley, and Aquafina dominate the market, with Mumbai consuming over 1,190 million litres annually, followed by Delhi at 1,036 million litres.
Despite its convenience, the bottled water industry has been scrutinized for using the same packaging machinery as sodas and carbonated beverages. These processes introduce an expiration timeline even for water. A Bisleri representative once stated, “While water doesn’t expire, our bottles are designed to last up to two years when stored correctly.” However, during India’s scorching summers, transportation and storage challenges often compromise quality.

Health Hazards Of Drinking Expired Bottled Water
Consuming water from expired plastic bottles can have serious health consequences. Chemicals leached from the degrading plastic have been linked to metabolic disorders, reproductive issues, and neurological problems. A 2020 study by the National Institute of Health identified that prolonged exposure to BPA could lead to hormonal imbalances and fertility issues.
Additionally, consumer anecdotal accounts highlight how poorly stored bottles develop an odd smell or taste. A woman from Chennai reported nausea after drinking bottled water left in her car for over two weeks during peak summer, demonstrating how environmental conditions exacerbate risks.
Safe Practices For Water Consumption
- Check Labels: Always check the expiration date and ensure proper storage conditions.
- Avoid Heat Exposure: Do not leave bottles in cars or under direct sunlight to prevent chemical leaching.
- Switch to Alternatives: Consider glass or stainless-steel bottles and invest in-home water filtration systems for sustainable options.
- Be Informed: Familiarize yourself with brands and their quality assurance processes. For instance, Bisleri has introduced tamper-proof seals to ensure safety.
In India, adopting eco-friendly measures like glass bottles or reusable containers can also reduce dependency on plastic packaging, ensuring both safety and sustainability.
While water itself is timeless and unspoiled, the packaging it comes in is not. Understanding the science behind bottled water expiration and the risks of improper storage is crucial. With India’s bottled water industry booming, consumers must demand safer packaging and adopt better consumption habits.
Water sustains life—but only when it’s safe to drink.
