Detailed explanation-1: -Without it, it will be extremely difficult to provide drinking water and water for crops and animals that would help communities during times of drought.
Detailed explanation-2: -Groundwater is water that has found its way down from the Earth’s surface into the cracks and spaces in soil, sand and rock. It is a critical source of drinking water and a key resource for agriculture, industry and natural ecosystems. However, groundwater supplies are under threat from overuse and pollutants.
Detailed explanation-3: -Groundwater is often cheaper, more convenient and less vulnerable to pollution than surface water. Therefore, it is commonly used for public water supplies.
Detailed explanation-4: -Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
Detailed explanation-5: -3% of the earth’s water is fresh. 2.5% of the earth’s fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth’s surface to be extracted at an affordable cost.
