ALTERNATIVE WAYS TO REDUCE ORGANIC AND NUTRIENT POLLUTION
FIGURE 13.47 Riparian forest buffers between agricultural fields and streams and rivers can significantly reduce nutrient pollution. Wastes from CAFOs can be controlled with an advanced treatment system such as this one, which can almost entirely eliminate organic and nutrient pollution by turning phosphorus wastes into commercial fertilizer, eliminating nitrogen wastes through denitrification, and eliminating almost all bacterial contamination. Or, reduced consumption of animal protein could allow a transition from CAFOs to lower-
