What type of water is categorized as non-potable?

• A. Desalinated water
• B. Rainwater
• C. Surface water
• D. All of the above

Answer: (B)

Water that is categorized as non-potable is water that is not safe for human consumption without treatment. Rainwater fits this classification because, while it can be collected and used for various purposes such as irrigation or flushing toilets, it typically contains contaminants from the atmosphere and surfaces it collects on. Desalinated water, which is produced through the process of removing salt from seawater, is actually treated to meet drinking water standards and is therefore considered potable. Surface water, on the other hand, such as lakes and rivers, may also be treated to be made potable, but in its natural state, it can contain pollutants and pathogens, making it non-potable without processing. Thus, the clear distinction lies in the fact that rainwater, while useful in many applications, does not meet the criteria for safe drinking water as it is generally not treated for that purpose initially.
