Drinking water that’s been sitting still is generally safe for short periods, but there are important factors to consider to ensure it remains safe and healthy. Understanding how long water can sit before it becomes unsafe and how to store it properly can help maintain its quality.
How Long Can Water Sit Before It Becomes Unsafe?
Water Safety Duration: Typically, water can sit safely for about 24 hours if it’s in a clean container and stored in a cool, dark place. Beyond this period, the risk of contamination increases.
- Room Temperature: Water left at room temperature should ideally be consumed within a day. Bacteria and algae can start to grow, especially if the water is exposed to light or heat.
- Refrigerated Water: Water stored in the refrigerator can last longer, up to a week, since the cooler temperature slows bacterial growth.
- Covered Containers: Using a covered container can help prevent contaminants from entering the water, extending its safe consumption period.
What Are the Risks of Drinking Stale Water?
Contamination Concerns: Water that sits for too long can become a breeding ground for bacteria, mold, and algae, especially if exposed to sunlight or stored in a dirty container.
- Bacterial Growth: Stagnant water can harbor bacteria such as E. coli, which can cause gastrointestinal issues.
- Chemical Leaching: If water is stored in plastic bottles, chemicals like BPA can leach into the water over time, especially if exposed to heat.
- Unpleasant Taste: Stale water can develop an off taste due to the absorption of odors from the environment or the growth of microorganisms.
How to Store Water Safely?
Proper Storage Tips: To ensure water remains safe to drink, follow these guidelines:
- Use Clean Containers: Always store water in clean, food-grade containers. Glass or stainless steel are preferable to plastic.
- Keep It Cool and Dark: Store water in a cool, dark place to reduce the risk of bacterial growth and chemical leaching.
- Seal Tightly: Ensure containers are sealed tightly to prevent contamination from dust, bacteria, or insects.
- Label and Date: If storing water for extended periods, label the container with the date of storage to keep track of freshness.
Can You Purify Stagnant Water?
Purification Methods: If water has been sitting for a while and you are unsure of its safety, consider purifying it before consumption.
- Boiling: Boiling water for at least one minute can kill most bacteria and pathogens.
- Filtration: Use a water filter to remove impurities and improve taste.
- Chemical Treatment: Water purification tablets or drops can help disinfect water in emergency situations.

How Can You Tell If Water Has Gone Bad?
Water typically doesn’t "go bad" like food, but it can become unsafe. Signs include a musty odor, cloudy appearance, or particles floating in it. If in doubt, it’s best to purify or discard the water.
Is It Safe to Drink Water Left in a Car?
Water left in a car, especially in plastic bottles, can become unsafe due to heat exposure, which promotes bacterial growth and chemical leaching. It’s advisable to avoid drinking water that’s been sitting in a hot car for extended periods.
Can Storing Water in the Fridge Keep It Safe?
Yes, storing water in the refrigerator can keep it safe for up to a week. The cold temperature slows down bacterial growth and helps maintain freshness.
What Is the Best Way to Store Tap Water for Emergencies?
For emergency storage, use clean, food-grade containers and store them in a cool, dark place. Rotate the water every six months to ensure freshness, and consider adding purification drops if necessary.
Does Boiling Water Remove Chemicals?
Boiling water kills bacteria and pathogens but does not remove chemical contaminants. For chemical purification, consider using a specialized water filter or chemical treatment.
Conclusion
Ensuring the safety of drinking water that’s been sitting requires attention to storage conditions and duration. By following proper storage practices, such as keeping water in clean, sealed containers and storing it in a cool, dark place, you can minimize the risks of contamination. If water has been sitting for an extended period, consider purifying it before drinking to ensure its safety. Always prioritize safe water consumption to maintain health and well-being.
