Introduction
Welcome, readers! How many times have you left a glass of water on the nightstand or a water bottle in the car and forgotten about it? Have you ever wondered how long can water sit out before it’s safe to drink? Or can it even be safe to drink at all?
This article will address those questions and more. You will learn about the science behind water, how long it can sit out, and the advantages and disadvantages of drinking it after it has been left out. We will also provide a comprehensive table and FAQs to guide you.
So, let’s dive in and learn about water and how long it can sit out.
How Long Can Water Sit Out?
The length of time water can sit out depends on several factors, including the temperature, container, filtration, and the source of the water.
Temperature
The temperature is a crucial factor in determining how long water can sit out. If the temperature is below 40°F or above 140°F, bacteria growth can occur, which can make the water unsafe to drink.
If the water is left out at room temperature, which is around 68°F to 72°F, it can be safe to drink for up to 2 days. However, if the temperature is higher, such as in the summer months, bacteria growth can occur in as little as a few hours.
Container
The container that holds the water is also a critical factor. If the container is dirty or contaminated, it can affect the safety of the water. Glass, stainless steel, or BPA-free plastic containers are the best options for storing water.
If the water is left out in a plastic container that contains BPA, it can affect the quality of the water and lead to health concerns.
Filtration
Filtration plays a critical role in ensuring the safety of water. If the water is filtered using a high-quality filter that removes impurities, it can be safe to drink even if it sits out for an extended period.
On the other hand, if the water is not filtered or filtered using a low-quality filter, it can lead to bacterial growth and affect the quality of the water.
Source of Water
The source of the water is also a crucial factor. If the water comes from a reliable and safe source, it can be safe to drink even if it sits out for an extended period.
However, if the water comes from an unreliable or contaminated source, it can lead to health concerns, even if it sits out for a short period.
Comprehensive Table
| Temperature | Container | Filtration | Source of Water | Safe to Drink? |
|---|---|---|---|---|
| Below 40°F or above 140°F | Dirty or contaminated | Not filtered or filtered using a low-quality filter | Unreliable or contaminated | No |
| Around 68°F to 72°F | Glass, stainless steel, or BPA-free plastic | High-quality filter | Reliable and safe | Yes, for up to 2 days |
Advantages and Disadvantages
Drinking water that has been left out for an extended period can have both advantages and disadvantages.
Advantages
One of the main benefits of drinking water that has been left out is that it can be an excellent remedy for dehydration. If you’re feeling dehydrated and don’t have access to fresh water, drinking water that has been left out can help rehydrate your body.
Additionally, leaving water out in the sun can help kill bacteria that may be present in the water.
Disadvantages
One of the main disadvantages of drinking water that has been left out is that it can lead to bacterial growth, which can make the water unsafe to drink.
Additionally, drinking water that has been left out for a long time can lead to a stale taste and odor, making it less desirable to drink.
