Maryland and surrounding states are undergoing a massive effort to clean up the Chesapeake Bay by reducing the pollution that goes into it. A core aspect of that cleanup on the land happens through best management practices, called BMPs for short. A best management practice is defined as a practice or combination of practices determined to be an effective means of reducing pollution generated by nonpoint sources (nonpoint sources of pollution are caused by water moving over or through the ground, which picks up pollution particles as it moves, eventually reaching the Chesapeake Bay or local tributaries). Best management practices can be implemented by a wide variety of entities, including a private property and business owners, farms, local and state government, and nongovernmental organizations.
