How are the sources of water supply classified?

Water supply sources are classified as groundwater and surface water based on their origin and the manner in which they are accessed. Groundwater refers to water that is stored beneath the earth's surface in aquifers and can be accessed through wells or springs. It is a vital resource for many communities, especially in rural areas where surface water may not be readily available.

Surface water, on the other hand, includes rivers, lakes, reservoirs, and streams that are found above the ground. This type of water is often used for municipal supplies, irrigation, and recreational activities. Furthermore, understanding this classification is essential for water management practices, conservation efforts, and ensuring the safety and quality of water supplies.

The other classifications, such as spring water and well water, rainwater and river water, or demineralized water and lake water, do not encompass the broader ecosystem and hydrological cycle in the way the classification of groundwater and surface water does. Thus, focusing on these two primary categories provides a clear framework for understanding water supply systems.
