groundwater

Because we have study that the 97% of earth water is in ocean and that is not fit for drinking the pure water is 3% which is in 2% in glacier,i ce caps ,rivers and lakes and remaining 1% is in underground water.i think you understand ......... thank you.....

Source of Drinking Water

One common source of drinking water is rivers and lakes. These natural bodies of water play a crucial role in providing clean and safe drinking water for millions of people worldwide. Let's explore why rivers and lakes are a common source of drinking water in detail.

1. Abundance of freshwater
Rivers and lakes are abundant sources of freshwater. They are formed by various natural processes such as precipitation, snowmelt, and groundwater flow. This freshwater is essential for the survival of both humans and ecosystems. It contains low levels of dissolved salts and is suitable for drinking purposes.

2. Natural filtration
Rivers and lakes act as natural filters, removing impurities and sediments from the water. As water flows through these bodies of water, it undergoes a natural purification process. The sediments settle down, and many impurities are trapped or degraded by microorganisms present in the water. This natural filtration helps improve the quality of the water.

3. Accessibility
Rivers and lakes are often easily accessible to human settlements. They are natural water sources found in many regions, making them convenient for the collection and distribution of drinking water. Municipalities and water authorities can establish treatment plants near these water bodies to supply clean water to nearby communities.

4. Renewable resource
Rivers and lakes are renewable resources of water. They are replenished by rainfall, snowmelt, and surface runoff, ensuring a continuous supply of water. Proper management and conservation of these water sources are necessary to maintain their sustainability and availability for future generations.

5. Water treatment
Although rivers and lakes are natural sources of freshwater, it is important to note that they still require treatment before being distributed as drinking water. Water treatment processes involve the removal of any remaining impurities, disinfection to kill harmful microorganisms, and the addition of necessary minerals to ensure safety and quality.

In conclusion, rivers and lakes are common sources of drinking water due to their abundance, natural filtration processes, accessibility, renewable nature, and suitability for treatment. However, it is crucial to implement proper water management practices and effective water treatment methods to ensure the provision of safe and clean drinking water to the population.
