These direct discharges are known as point sources because they can be traced to a specific point of origin. The polluter can be required to obtain a permit and uphold certain water quality standards for point source pollution. Conservation of our nation's remaining wetlands provides one of the best means of defense against polluted runoff. The scientific link between functioning wetland systems and improved water quality is well established. Wetlands, commonly known as marshes or swamps, filter out pollutants from contaminated runoff through natural processes that improve the quality of water downstream.
Wetlands are a crucial, natural mechanism for protecting and restoring water quality.
Wetland protection must be an essential part of our nation's efforts to ensure clean water for all.
