Some of these pollutants may be buried in the sediments, while others may be converted into less harmful chemical forms by biological processes or by exposure to sunlight for extended periods.
Still other pollutants may be taken up by the plants. Some freshwater wetlands are located at points where surface water enters an underground aquifer, thereby recharging groundwater supplies. Wetlands are more often points of groundwater discharge to the surface of the land, such as springs. The groundwater discharge may be important as a local drinking water source or important for providing stream flows for fish, animals, plants, and other organisms that live on or near the stream during dry summer months.
According to the Vermont Wetland Rules , wetlands that make an important contribution to the protection or enhancement of the quality of surface or of ground water are significant wetlands.
In determining whether a wetland is significant for the Surface and Ground Water Protection function,the Secretary or Panel shall, at a minimum, consider the extent to which it:. Recharges a drinking water source, such as a well head or source protection area. Reduces levels of contaminants in surface waters which recharge underlying or adjacent groundwaters. Contributes to the flows of Class A surface waters. Enhances or protects water quality through chemical action, by the removal of nutrients, by the retention or removal of sediments or organic matter, or by moderating the adverse water quality effects of soil erosion or stormwater runoff.
By storing rain like a sponge, and by buffering us from the sea they can protect us from floods, tsunamis and cyclones. Wetlands can also protect us from droughts and reduce air temperatures by up to 10 degrees Celsius. Wetlands have supported human life for millenia and are essential for human health and prosperity.
From the Nile to the Mekong, civilisations sprang up around wetlands, and all around the world they continue to provide us with food, water, supplies, transport and leisure. Wetlands not only hold most of our available fresh water, they also improve its quality by naturally filtering pollutants.
Our connection with nature and particularly wetlands is essential for maintaining our health and wellbeing. Invasive species, pollution, unsustainable development and climate change are all taking their toll with wetlands under more pressure than ever before. Unlike ancient woodland and rainforest that take centuries to regenerate, new technology means WWT can create new wetlands in a matter of months and years.

Incredible things happen when land and water meet. Why wetlands are amazing Wetlands teem with biodiversity. Every year new species are discovered in freshwater wetlands. Coastal wetlands like mangroves are among the most biologically diverse places on earth. Action to protect wetlands is a key part of the fight against climate change.
That's a 50 percent loss. During the s, people began to recognize the benefits of wetlands. In addition to hosting a wide variety of plant and animal life, wetlands also provide water storage, filtration and offer us protection from floods.
Unfortunately, the majority of wetlands in this country are located on private land, so the government can only do so much. The government also has recently put focus on restoration and wetland creation. Worldwide, threats to wetlands continue. Human exploitation, climate change, military activity, and drought all degrade or destroy the planet's wetland areas. For instance, in only 30 years, the Philippines has lost 80 percent of its coastal wetlands [source: WWF ].

A watershed is an area that drains to a common waterway, like a creek or stream -- which then drains to a larger body of water, like the ocean. Wetlands provide a link between watershed and water.
