What does 'raw water' refer to?

• A. Water that has undergone filtration
• B. Water in its natural state, prior to any treatment or processing
• C. Water that is extracted from deep wells
• D. Water that is stored in reservoirs

Answer: (B)

The term 'raw water' refers to water that exists in its natural state, before any treatment or processing has taken place. This includes surface water from rivers, lakes, and reservoirs, as well as groundwater from aquifers. It has not yet undergone filtration, disinfection, or any other form of purification, which is essential for making it safe for human consumption. Understanding raw water is critical for water operators, as it represents the starting point in the water treatment process. Operators must be aware of the quality, composition, and potential contaminants present in raw water to effectively treat and ensure it meets safety standards before distribution. The other options do not accurately describe raw water: it is not water that has been filtered or extracted specifically from deep wells, nor is it limited to what is found in reservoirs. Instead, raw water encompasses all sources of untreated water.
