Bioreactors ready for the big time

Bioreactors are passive filtration systems that can reduce nitrate losses from farm fields. Most bioreactors are simple pits filled with wood chips; bacteria on the wood chips remove 25 to 45 percent of the nitrate in runoff water. New research highlights their potential applications and provides insight into design options.
