The building of a bioreactor
By Joseph L. Murphy
Watch this time-lapse video of the construction of a bioreactor in the Elk Run Watershed near Carroll, Iowa. The Bioreactor will treat water from a 30-acre area in the Elk Run watershed near Carroll, Iowa. Bioreactors remove about 43 percent of the nitrates in water and last 10 to 15 years. The installation was part of a Agriculture's Clean Water Alliance project that was paid for by a Water Quality Initiative grant from the Iowa Department of Agriculture and Land Stewardship. ISA staff provide administrative, technical and communications support.
