Thompkins Contracting, Inc completed the Woodchip Bio-Reactor Project last week in Bonita Springs, FL. The bio-reactor is now up and running in an effort to keep the Imperial River clean. The City of Bonita Springs implemented this project to help protect the local environment and prevent the river from becoming a dead zone.
A bio-reactor consists of subsurface trenches filled with wood chips through which drainage water flows before entering a surface water body, such as a stream or lake. The woodchips assist with the filtering of nitrates, a common form of nitrogen, from the water by converting it into nitrogen gas. High levels of nitrogen have been discovered in the local Imperial River, causing the community great concern. If nitrogen levels rise too high then can cause water systems to become dead zones, eventually breaking down entire aqua-habitats. High nitrogen levels can be caused by many factors, one of which is the use of fertilizers in farms and gardens.
The Woodchip Bio-Reactor site, located on the city-owned blocks of Felts Avenue and Abernathy Street in downtown Bonita Springs, is now open to the public. It offers a parking area, information booth, and large shaded trees.
