Typical animal feeding operations (AFOs) produce large quantities of manure which are often stored in lagoons then land applied to nearby crop fields. Off-site movement of the manure as well as other fertilizers through storm water runoff or percolation to groundwater has been recognized as a source of contamination of water bodies. This is especially true in east Tennessee with high rainfall, karst landscapes and substantial topographic relief. One control technology for remediating agricultural chemicals, such as nitrogen (N), is the promotion of denitrification using denitrification beds, also called underground reactive barriers. A denitrification bed is constructed by mixing an organic carbon (C) source (typically sawdust or woodchips) with the soil below the water table in order to intercept groundwater flow. The increased and continued supply of C to denitrifiers enhances denitrification of the groundwater, thus reduced NO3- in the discharge. Due to the decade long drive of bio-energy industry, the ... 전체 초록 보기
