In the European Union (EU), since 2000, the Water Framework Directive (WFD) aims to achieve a number of objectives to improve water quality of lakes, rivers and coastal areas. [23] Key objectives are general protection of the aquatic ecosystem, protection of drinking water resources, and protection of swimmable waters. [ 23 ]
Marshes also improve water quality by acting as a sink to filter pollutants and sediment from the water that flows through them. Marshes (and other wetlands) are able to absorb water during periods of heavy rainfall and slowly release it into waterways and therefore reduce the magnitude of floodin The pH in marshes tends to be neutral to ...
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.

Some examples of these hazards include habitat loss, pollution, and invasive species.

Constructed wetlands are designed to improve water quality by supporting rooted vegetation arranged to physically remove solids and particulate material while removing soluble nutrients in the water by uptake into plant tissue and supplying oxygen to the water to reduce BOD.
Considered by some the most important of the projects, the reservoir, at 10,500 acres (4,249 hectares), will have the capacity to store enough water for the equivalent of about 480,000 to 720,000 homes. Its adjacent 6,500-acre (2,630.5 hectares) wetland – or the stormwater treatment area – will clean reservoir water before it’s discharged.
Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary.
