What are the two types of Potable Water Sources?

• A. Surface water and groundwater
• B. Ground water and surface water
• C. Rainwater and groundwater
• D. Municipal water and well water

Answer: (B)

Two main categories describe where potable water comes from: water from the surface (such as lakes, rivers, and reservoirs) and water from the ground (groundwater stored in aquifers). These two cover the primary ways drinking water is sourced in most systems, and the order in which they’re listed doesn’t change the idea. Rainwater can be used as a source in some setups but isn’t one of the standard broad categories for potable supply, and terms like municipal water vs well water refer to a distribution system or a specific source rather than the two fundamental hydrologic categories.
