What are the two main potable water sources?

• A. Ground water and surface water
• B. Surface water and rainwater
• C. Ground water and bottled water
• D. Ground water and seawater

Answer: (A)

Public drinking water typically comes from two primary sources: groundwater and surface water. Groundwater is water stored underground in aquifers and accessed through wells; it often provides a steady supply and can be treated to meet safety standards. Surface water comes from lakes, rivers, and reservoirs and usually requires treatment to remove contaminants before it’s safe to drink. These two categories cover the vast majority of potable water systems. Rainwater can supplement supplies in some places but isn’t the standard main source for most utilities. Bottled water is a consumer product, not a municipal source. Seawater isn’t potable without desalination, so it isn’t a typical main source for drinking water.
