According to research, constructed wetlands can help the environment.
This is the Iowa Environmental Focus.
Constructed wetlands can reduce nutrients, collect sediment, slow flood water and improve biodiversity, said co-author J. Elizabeth Maas of Iowa City, a landscape consultant and restoration ecologist.
Iowa Policy Project founding director David Osterberg acknowledged that runoff from farm fields contributes most of the nitrogen and phosphorus loading that constitutes the chief pollutant of Iowa waters.
The recent climate shift toward more extreme rainfall events accentuates the need for measures to control runoff.

The Iowa Policy Project is a nonpartisan, nonprofit public policy research organization based in Iowa City
