Unavoidable adverse impacts are negative effects on wetlands that cannot reasonably be avoided or minimised, therefore requiring compensatory mitigation. The mitigation sequence is used as a tool to guide the type and level of compensatory mitigation that will be required under the Clean Water Act. [10]
Wetlands play a significant role in the diets of many people all over the world. Wetlands are home to over 100,000 biodiverse species of plants, animals, and bacteria. Wetlands are crucial to for the development of society, as they account for more than a billion services and jobs a year, which is valued at $47 billion worldwide.
CWN was formed in 1992 as a project of the Natural Resources Defense Council. [1] The primary functions of CWN are to coordinate a variety of public interest organizations on clean water issues so that these groups may combine resources and advocate together and to "safeguard water quality for future generations by working to defend, strengthen, and implement the Clean Water Act and other key ...
Similar to natural wetlands, constructed wetlands also act as a biofilter and/or can remove a range of pollutants (such as organic matter, nutrients, pathogens, heavy metals) from the water. Constructed wetlands are designed to remove water pollutants such as suspended solids, organic matter and nutrients (nitrogen and phosphorus). [3]
Protection of wetlands and small streams is a major focus of the Clean Water Rule.

The Federal program was administered by the Army Corps of Engineers, which focusses on navigable waters ...
Most of the organisms involved are derived from the waste, wastewater or water stream itself or from the atmosphere or soil water. However some processes, especially those involved in removing very low concentrations of contaminants, may use engineered eco-systems created by the introduction of specific plants and sometimes animals.
A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
