The author in front of a woodchip pile destined for a denitrification bioreactor on a farm field owned by the City of Cedar Rapids. The bioreactor is anticipated to reduce nitrate levels up to 60 percent from a farm tile drain that outlets to Indian Creek in Linn County, Iowa. The City of Cedar Rapids has provided direct financial contributions to assist farmers with building conservation practices, such as denitrifying bioreactors, in partnership with groups such as the Indian Creek Watershed Management Authority.
