What kind of water is defined as free from impurities?

The definition of water that is free from impurities corresponds to potable water. This type of water meets health and safety standards for human consumption and is treated to remove harmful substances, ensuring it is safe for drinking and cooking.

Potable water is essential for public health and is carefully monitored and regulated to maintain its purity. It should not contain pathogens, toxins, or other contaminants that could pose a health risk.

In contrast, contaminated water refers to water that has been adversely affected by pollutants and is therefore unsafe for consumption. Greywater is used water from sources like sinks and showers, which may contain contaminants but can be recycled for non-potable uses. Stormwater is rainwater that has run off surfaces and can carry pollutants, making it unsuitable for consumption without proper treatment.
