On September 3 & 4, 2013, a denitrifying bioreactor was installed on the Mike Knipper farm near Dyersville, IA. The Knipper farm is located in the Hewitt Creek Watershed which drains into the North Fork Maquoketa River. This is the second bioreactor to be installed in the watershed, and the third one in northwest Dubuque County. The following videos track the installation of the bioreactor. The installation was coordinated by ISU Extension staff and Vonderhaar Construction of Guttenberg, IA.
The videos were shot with a Samsung Galaxy Aviator phone by a novice audio/video technician.
