Detailed explanation-1: -Wetlands purify our water by removing sediments and other pollutants including chemicals. Wetlands also filter and process excess nutrients that may runoff from agricultural and development sites. Wetlands have been called “the kidneys of our watersheds.”

Detailed explanation-2: -Constructed wetlands make use of the natural purification processes of vegetation, soils and microbes to remove contaminants from discharge. Uses of constructed wetlands for water purification include applications in industrial wastewater and municipal wastewater and storm water treatment.

Detailed explanation-3: -One of the most important benefits that wetlands provide is their capacity to maintain and improve water quality. When healthy, wetlands have a rich natural diversity of plants and animals. These can act as filtering systems, removing sediment, nutrients and pollutants from water.

Detailed explanation-4: -Wetlands are vital ecosystems. Home to 40 percent of the world’s species, they protect us from flooding, provide food and clean water, and play a crucial role in combating climate change.
