What is the typical temperature range for water storage to inhibit bacterial growth?

The typical temperature range for water storage that inhibits bacterial growth is between 40°F and 140°F. This range is significant because it falls within what is commonly referred to as the "danger zone" for food safety, where bacteria can rapidly multiply. Water stored within this temperature range can encourage the growth of harmful microorganisms, which is why it is critical to keep water outside of this range.

When water is stored below 40°F, microbial growth is greatly slowed, as colder temperatures inhibit bacterial activity. Conversely, when water is maintained above 140°F, it kills most bacteria and pathogens, effectively providing a safe environment. Therefore, acknowledging the dangers associated with stored water being within that specific temperature range is essential for ensuring public health, particularly in small water systems where sanitation practices are crucial.

While other choices may refer to extremes or less relevant temperature conditions, only the range from 40°F to 140°F accurately reflects the harmful environment that promotes bacterial growth, making it the correct selection in this context.
