A water source is a natural or artificial location where water is collected or flows from. Common examples include rivers, lakes, ponds, and aquifers. These sources provide water for various uses, such as drinking, irrigation, and industrial processes. Water sources can be classified into surface water and groundwater. Surface water comes from rain or melting snow that collects in rivers and lakes, while groundwater is found beneath the earth's surface in soil and rock formations. Both types are essential for sustaining ecosystems and human activities, making them vital resources for communities and the environment.
