An establishment must use potable water for all food-related tasks. Which of the following is an example of potable water?

The correct answer is drinking water because it is specifically defined as safe and suitable for human consumption, meeting the health and safety standards required for potable water. Drinking water undergoes treatment processes to remove contaminants and ensure it is safe for drinking and food preparation, making it ideal for all food-related tasks in a food establishment.

In contrast, tap water from the kitchen sink may generally be potable, but this can vary based on the plumbing and local water quality standards, hence it is not always guaranteed to be safe without further context. Rainwater collected in barrels does not meet the standards of treated potable water unless it has undergone the necessary purification treatments, which are not typically standard in most collection methods. Additionally, water from a swimming pool is treated with chemicals such as chlorine, making it unsuitable for consumption and food preparation, as it can pose health risks.
