Yes, it is generally safe to drink 20-year-old bottled water, provided it has been stored properly in a cool, dark place and the bottle remains sealed. While the water itself doesn’t typically expire, the plastic bottle can degrade over time, potentially leaching chemicals into the water.
Can You Drink Old Bottled Water? Understanding the Risks
Many people wonder about the safety of consuming bottled water that has been sitting around for years. The good news is that water itself doesn’t expire. Unlike perishable food items, pure water doesn’t harbor bacteria or spoil. However, the container it’s stored in plays a crucial role in its long-term safety and quality.
What Happens to Bottled Water Over Time?
While the water remains chemically the same, the plastic bottle is the main concern. Over extended periods, especially when exposed to heat or sunlight, the plastic can begin to break down. This process is known as leaching, where chemicals from the plastic can migrate into the water.
- BPA and Phthalates: Many older plastic bottles may contain Bisphenol A (BPA) or phthalates. These chemicals have raised health concerns, with potential links to endocrine disruption and other issues. Newer bottles often use BPA-free plastics, but degradation can still occur.
- Taste and Odor: Even if the water remains safe to drink, you might notice a change in its taste or smell. The plastic can impart a stale or chemical flavor over two decades.
How to Assess the Safety of Old Bottled Water
Before you consider drinking water that’s 20 years old, a few checks are essential. Your health and safety are paramount, so don’t take chances if you have doubts.
- Inspect the Bottle: Look for any signs of damage, such as cracks, dents, or discoloration. A compromised bottle is a clear indicator that the water may not be safe.
- Check the Seal: Ensure the cap is still securely sealed and hasn’t been tampered with. A broken seal means the water has been exposed to the environment.
- Evaluate Storage Conditions: Was the water stored in a cool, dark place, away from direct sunlight and extreme temperatures? Bottles stored in a hot car or garage for years are more likely to have leached chemicals.
- Smell and Look: If the seal is intact and the bottle looks good, give it a sniff. If it smells off or plastic-y, it’s best to discard it. Also, check if the water appears cloudy or has any sediment.
Storing Bottled Water for Longevity: Best Practices
Proper storage is key to maintaining the quality and safety of bottled water, even if you don’t plan to drink it after 20 years. Following these guidelines will help preserve your water supply.
- Cool and Dark: Always store bottled water in a cool, dark environment. A pantry, basement, or closet is ideal. Avoid storing it near windows or in direct sunlight.
- Stable Temperatures: Try to maintain a consistent temperature. Fluctuations can accelerate the degradation of the plastic.
- Original Packaging: Keep bottles in their original cardboard cases if possible. This offers an extra layer of protection against light and damage.
- Avoid Chemical Proximity: Do not store bottled water near chemicals, fuels, or strong-smelling substances, as the plastic can absorb odors.
The Lifespan of Bottled Water: What Experts Say
While the water itself is stable, manufacturers typically recommend consuming bottled water within a certain timeframe, usually one to two years. This recommendation is primarily due to potential changes in taste and the slight possibility of chemical leaching from the plastic over extended periods.
For water stored for 20 years, the risk isn’t necessarily from the water itself becoming "bad" in a microbial sense, but from the potential degradation of the PET (polyethylene terephthalate) plastic. This is especially true if the water was not stored under ideal conditions.
Alternatives to Drinking Very Old Bottled Water
If you have 20-year-old bottled water and are uncertain about its safety, or if it has an off-putting taste, there are many readily available and safer alternatives.
- Tap Water: In most developed areas, tap water is rigorously tested and safe to drink. Consider using a water filter for enhanced purity and taste.
- Freshly Bottled Water: If you need bottled water, purchase new supplies. Look for bottles made from BPA-free plastics or consider glass bottles for longer-term storage.
- Filtered Water Pitchers: These are an economical and convenient way to get clean, great-tasting water at home.
When to Absolutely Discard Old Bottled Water
There are certain situations where you should immediately discard old bottled water, regardless of how it was stored.
- Damaged or Compromised Bottle: Any visible damage to the bottle or cap.
- Broken Seal: If the seal is broken or appears to have been tampered with.
- Cloudy Appearance: If the water looks cloudy, discolored, or contains visible particles.
- Unpleasant Odor: A strong chemical, plastic, or musty smell.
- Unknown Storage History: If you have no idea how or where the water was stored.
People Also Ask
### Can 20-year-old bottled water make you sick?
While unlikely to cause immediate illness if the bottle is intact and stored properly, drinking very old bottled water carries a small risk. The primary concern is the potential leaching of chemicals from degraded plastic into the water over two decades. If the water smells or looks off, it’s best to avoid it to prevent any potential adverse health effects.
### Does bottled water expire if the seal is broken?
Yes, if the seal on a bottle of water is broken, it significantly reduces its shelf life and safety. Once opened, the water is exposed to air and potential contaminants. It can absorb odors from its surroundings and may begin to develop a stale taste. It’s generally recommended to consume opened bottled water within a few days.
### Is it safe to drink bottled water left in a hot car?
Drinking bottled water that has been left in a hot car is generally not recommended, especially if done repeatedly or for extended periods. High temperatures can accelerate the breakdown of the plastic, leading to increased leaching of chemicals like BPA into the water. While a single instance might not be harmful, it’s a practice to avoid for long-term health.
### How long is bottled water actually good for?
Manufacturers typically recommend consuming bottled water within one to two years for optimal taste and quality. The water itself doesn’t spoil, but the plastic bottle can degrade over time, potentially affecting the water’s flavor and, in rare cases, its safety due to chemical leaching, especially if stored improperly.
### What are the health risks of drinking old plastic bottled water?
