Bottled Water Safety Guide: How Long Is Bottled Water Good After Expiration?

bottled water safety guide

The topic of drinking expired bottled water is one that often raises eyebrows and sparks debate. Unlike most bottled beverages, bottled water is generally considered safe to consume even past its expiration date. While many people may find this surprising, numerous reliable sources have backed up this assertion.

These sources agree that water, due to its inherent stability as a compound, does not technically go bad or expire. Even the U.S. Food and Drug Administration, which regulates bottled water, does not require an expiration date to be listed on the product. Consequently, even if your bottled water has surpassed its printed expiration date, it is typically still safe to drink.

However, while the water itself doesn’t degrade or spoil, certain factors can influence the quality and safety of bottled water over time. 

Factors That Affect the Safety of Expired Bottled Water

While bottled water generally remains safe to drink even beyond its expiration date, certain factors can potentially affect its safety and quality. Here are some crucial considerations:

Storage Conditions

Bottled water should ideally be stored in a cool, dry place away from sunlight. Heat and light can accelerate the degradation of the plastic bottle, potentially causing chemicals to leach into the water. If bottled water is stored in conditions that are too warm or exposed to sunlight, consuming this water could expose you to harmful chemicals that may have adverse health effects, including hormonal disruption and an increased risk of certain cancers.

Bottle Integrity

The physical condition of the bottle plays a key role. If the bottle is cracked, scratched, or damaged in any way, it can become a breeding ground for bacteria, making the water unsafe to drink. Drinking from such a bottle could lead to gastrointestinal issues, such as diarrhea, vomiting, and stomach cramps, caused by bacterial contamination.

Seal Integrity

A compromised seal can allow contaminants to enter the bottle. Always check to ensure that the seal is intact before drinking from an expired bottle of water. If the seal is compromised, consuming this water could lead to the ingestion of foreign substances or pathogens, potentially resulting in illnesses ranging from minor gastrointestinal discomfort to more serious diseases, depending on the nature of the contaminant.

Quality of the Original Water Source

The initial quality of the water at the time of bottling is also important. If the water was contaminated at the source, it could become more unsafe over time. Consuming such water could lead to chronic health issues like heavy metal poisoning or parasitic infections.

Type of Plastic Used in the Bottle

Not all plastics are created equal. Some types of plastic can leach harmful chemicals into the water over time, especially when exposed to heat. Single-use bottles are usually made from PET (Polyethylene Terephthalate) or HDPE (High-Density Polyethylene), while Tritan, a BPA-free plastic, is safe for repeated use

Always opt for ‘BPA-free’ labeled bottles to avoid potential chemical exposure. Consuming water from low quality bottles could lead to long-term health effects such as endocrine disruption and an increased risk of certain cancers.

How to Store Bottled Water Properly and Its Shelf Life

The FDA states that bottled water, when stored correctly, remains safe for consumption indefinitely. However, it’s generally recommended to consume the water within 1-2 years from the bottling date. This advice is due to the potential for chemicals to leach from the plastic bottle into the water over time.

Plastic bottles are semi-permeable and can allow certain substances to pass through. This can lead to microorganisms seeping into the water, especially when the bottles are exposed to heat or direct sunlight. The integrity of the bottle’s seal is also of utmost importance. If the seal is damaged or compromised because of improper storage, contaminants could invade the bottle, making the water unsafe to drink.

Moreover, it’s crucial to store bottled water away from other chemicals. If chemicals are stored nearby, they can permeate the plastic and alter the water’s taste. Therefore, to maintain the freshness and quality of your bottled water, it’s imperative to store it away from chemicals and in a cool, dry place, away from direct sunlight.

Steps to Take if Your Bottled Water is Suspected to be Compromised

Bottled water, when sealed and stored properly, is generally safe for consumption. However, if you suspect that your sealed bottled water is compromised, it’s crucial to take immediate action to ensure safety.

Contact Relevant Authorities

If the water seems suspicious or has an unusual smell or appearance, it’s recommended to reach out to your local health department or the Environmental Protection Agency’s Safe Drinking Water Hotline. They can provide guidance on the potential causes of the water problems and recommend the next steps.

Inspect the Bottle and Water

Carefully examine the water bottle. Look for signs of a broken seal, damage to the bottle, or any irregularities. Also, check the water for any discoloration, cloudiness, or unusual smell.

Check the Source of the Water

Always read the label on the bottle. Bottled water could be sourced from different places, including municipal sources, springs, or wells. If the water is from a municipal source or a community water system, it indicates it’s treated tap water.

Discard or Boil the Water

If the quality of the water is suspected to be compromised, it’s safer to discard it. However, if no other water source is available, boiling the water can kill most types of disease-causing organisms.

It’s important to note that using compromised bottled water to water plants is not recommended. The contaminants in the water could potentially harm the plants or alter the soil composition.

Safe Drinking Water: A Crucial Resource During Emergencies

In times of emergencies or natural disasters, access to safe drinking water becomes a critical need. This guide provides important steps and considerations to ensure the safety and quality of your bottled water resources. By being aware of potential risks, understanding how to identify signs of contamination, and knowing how to respond, you can protect yourself and your family from the health hazards of compromised bottled water.

Always keep in mind how important it is that your drinking water be safe. In situations where the integrity of your water supply may be in question, these measures can make a significant difference. Stay prepared, stay informed, and ensure your water is safe for consumption.
