Wider buffers are better

When protecting wetlands from nitrogen pollution, an EPA study points to wider, vegetated borders around streams as most effective

MADISON, WI, JULY 26, 2007- Excess nitrogen caused by fertilizers, animal waste, leaf litter, sewer lines, and highways is responsible for contaminating groundwater. It can also cause human health risks when found in drinking water and oxygen depleted water bodies endangering animals that drink from them. Establishing Riparian buffers is considered a best management practice (BMP) by State and Federal resource agencies for maintaining water quality, and they may be especially critical in controlling amounts of human produced nitrogen.
