Access to clean, safe drinking water is crucial for health and well-being. Knowing how to store water properly is vital, whether you're preparing for an emergency, improving your daily hydration routine, or simply want to ensure the quality of your drinking water. This guide explores the best practices for storing drinking water, addressing common concerns and providing practical tips.
What is the Best Container for Storing Drinking Water?
The ideal container for storing drinking water is food-grade, non-reactive, and clean. This means avoiding materials that can leach chemicals into the water, altering its taste or posing health risks.
Recommended Containers:
- Food-grade plastic: Look for containers specifically labeled as BPA-free and designed for water storage. High-density polyethylene (HDPE) #2 and high-density polypropylene (HDPE) #5 plastics are generally considered safe.
- Glass: Glass is an excellent choice as it's inert and won't affect the water's taste or quality. However, it's more fragile than plastic.
- Stainless steel: Stainless steel is durable, safe, and doesn't impart flavors. Ensure it's food-grade stainless steel.
Containers to Avoid:
- Recycled plastic containers: These may not be food-grade and could contain contaminants.
- Containers with damaged seals or cracks: These can allow bacteria or other contaminants to enter.
- Unlabeled plastic containers: You can't be sure of the type of plastic used.
- Cardboard containers: Cardboard is porous and can easily become contaminated.
How Long Can You Store Water in Different Containers?
The shelf life of stored water depends on several factors, including the container, storage conditions, and initial water quality. While the water itself might not spoil in the traditional sense, its quality can deteriorate over time.
- Plastic containers (BPA-free): Stored properly, water in BPA-free plastic containers can remain safe for up to 6 months.
- Glass containers: Water in properly sealed glass containers can last for much longer, potentially years, provided it's stored correctly.
- Stainless steel containers: Similar to glass, water stored in stainless steel containers can last for a long time if kept clean and sealed properly.
How to Store Drinking Water Properly: Best Practices
Proper storage is key to maintaining the quality of your drinking water. Here are some crucial steps:
- Cleanliness is crucial: Thoroughly clean and sterilize containers before filling them with water.
- Proper sealing: Ensure the container is tightly sealed to prevent contamination.
- Cool, dark place: Store water in a cool, dark place away from direct sunlight and heat. Sunlight can degrade the water quality.
- First In, First Out (FIFO): Rotate your water supply regularly, using older water first.
- Check for contamination: Regularly inspect containers for any signs of damage, leaks, or unusual odors.
What is the Best Way to Purify Water for Storage?
If you're concerned about the purity of your source water, purification is essential before storing it. Consider these options:
- Boiling: Boiling water for 1 minute kills most harmful bacteria and viruses.
- Water filters: Use a high-quality water filter designed for removing contaminants. Look for filters that remove sediment, chlorine, and other impurities.
- Water purification tablets: These tablets are a convenient way to purify water in emergencies. Follow the manufacturer's instructions carefully.
Can I Store Tap Water?
Yes, you can store tap water, but its quality and shelf life depend on your local water supply. It's advisable to purify tap water before storing it, especially if your tap water has a high chlorine content or other impurities.
How Long Does Bottled Water Last?
Bottled water typically has an expiration date printed on the bottle. After this date, the quality of the water may decline, although it's unlikely to become immediately dangerous. Always check the expiration date and follow the manufacturer’s instructions.
Conclusion
Storing drinking water correctly is a vital skill, whether for everyday use or emergency preparedness. By following these guidelines and choosing appropriate containers, you can ensure access to clean, safe drinking water whenever you need it. Remember, always prioritize cleanliness, proper sealing, and cool storage to maintain the best possible quality.
