More than 68% of freshwater on the Earth is trapped in the form of icebergs and glaciers in the Arctic and Antarctic regions. Nearly 30.90% is present in the form of underground water, which exists between rocks and the soil surface. Around 0.4% of freshwater is present as surface freshwater in the form of lakes, rivers, and wetlands. These include various water springs and other small freshwater resources, like ponds and reservoirs. Almost all of the Earth's water is saline and is inconsumable directly. From the small amount of freshwater, a relatively small portion is available to sustain human, plant, and animal life. Freshwater is vital for a majority of biological organisms. It is estimated that less than 0.01% of the freshwater available on the Earth is found in lakes, swamps, and rivers. Other freshwater sources, such as glaciers and underground water, contribute to around 2.5% of the world’s water content. Freshwater, even though abundantly available, is a limited resource to humanity and the environment. The increasing need for mechanization and food safety led to excessive usage of the available freshwater resources in the past century. This has created an ecological imbalance, as the wastewater produced from agriculture, industrial processes, and sewage water was discarded into freshwater resources.
