The correct answer highlights the focus of the Coastal Zone Management Act (CZMA) on nonpoint source pollution. This type of pollution refers to contaminants that are not discharged from a single, identifiable source but rather come from multiple, diffuse sources, often related to land runoff. Nonpoint source pollution can include agricultural runoff, urban runoff, and other forms of pollution that accumulate and enter coastal waters.

The CZMA encourages states to implement measures to manage coastal resources effectively and prevent this kind of pollution because it can severely impact coastal ecosystems, water quality, and the overall health of marine environments. By addressing nonpoint source pollution in their coastal management programs, states can better protect natural resources, recreational activities, and public health in coastal areas.

The other choices refer to specific types of pollution that, while important, do not align with the primary focus of the CZMA, which is centered around the challenges posed by nonpoint sources. Understanding this distinction helps clarify the broader objectives of coastal zone management in protecting marine and coastal environments.
