Nonpoint source pollution is potentially more harmful because:

1. Diffuse nature: Nonpoint sources are widespread and difficult to identify, making regulation and mitigation challenging.

2. Cumulative impact: Small amounts of pollutants from multiple nonpoint sources can accumulate and cause significant harm.

3. Lack of treatment: Nonpoint sources often bypass treatment systems, releasing pollutants directly into waterways.

4. Variability: Nonpoint source pollution can vary greatly depending on factors like weather, soil type, and land use.

Point sources, on the other hand, are:

1. Identifiable: Point sources are discrete, easily identifiable, and regulated (e.g., factories, wastewater treatment plants).

2. Treatable: Point sources can be treated and monitored to reduce pollutant discharge.

3. Regulated: Point sources are subject to permits, standards, and enforcement.

Key differences:

Point Sources:

- Industrial facilities

- Wastewater treatment plants

- Sewage overflows

- Spills
