In-stream wetland mitigation of nitrogen contamination in a USA Coastal Plain Stream

Nonpoint source N from riverine origin is a major water quality problem throughout the world. Nitrogen removal from a contaminated (6.6 mg L-1, NO3(-)N) stream was evaluated in this study using an in-stream wetland (ISW). The ISW was established at the exit of a 425-ha USDA Water Quality Demonstrati...

Description
Summary:Nonpoint source N from riverine origin is a major water quality problem throughout the world. Nitrogen removal from a contaminated (6.6 mg L-1, NO3(-)N) stream was evaluated in this study using an in-stream wetland (ISW). The ISW was established at the exit of a 425-ha USDA Water Quality Demonstration watershed in the Coastal Plain of North Carolina. It ranged in depth from about 0.2 to 2 m, and it was
