Watersheds or drainage basins are an area of land that drain into a common water body such as stream, lake, estuary, aquifer or ocean. [13] The Watershed Approach is an important framework to address today's water challenges. More than $450 billion in food and fiber, manufactured goods, and tourism depends on clean water and healthy watersheds.
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
Most organisms involved in water purification originate from the waste, wastewater or water stream itself or arrive as resting spore of some form from the atmosphere. In a very few cases, mostly associated with constructed wetlands , specific organisms are planted to maximise the efficiency of the process.
In a 5-4 vote, the Supreme Court limits federal protection for wetlands in a property rights case, saying the Clean Water Act does not usually apply to the marshy areas.
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.

Classifying water as "of the U.S." or "not of the U.S." for purposes of enforcing the Clean Water Act suggests a natural boundary that probably does not exist in nature, and one that was not created regarding air for purposes of enforcing the Clean Air Act. Indiana Wetlands are the focus of the U.S. National Wetlands Coalition, which in turn ...
In the United States, federal agencies (under section 404 of the Clean Water Act (CWA)), as well as many state and local governments, require compensatory mitigation (described as biodiversity offsetting in other countries) for the disturbance or destruction of wetland, stream, or endangered species habitat.
Protection of wetlands and small streams is a major focus of the Clean Water Rule. The Clean Water Rule is a 2015 regulation published by the U.S. Environmental Protection Agency (EPA) and the United States Army Corps of Engineers (USACE) to clarify water resource management in the United States under a provision of the Clean Water Act of 1972.
