Which of the following is typically associated with point source pollution?

Point source pollution refers to contaminants that are discharged from a single, identifiable source, making it easier to monitor and regulate. Oil spills are classic examples of point source pollution because they originate from a distinct location, such as an oil rig, tanker, or pipeline. When oil is released from these sources, it creates a concentrated area of pollution that can be traced back to that specific point, which is crucial for environmental management and cleanup efforts.

In contrast, stormwater runoff, agricultural runoff, and fertilizer use are typically associated with non-point source pollution. These involve a diffuse source where pollutants accumulate over areas and are washed into water bodies through rain or irrigation without a clear or single origin. Hence, while the other options contribute significantly to water quality issues, they do not fit the definition of point source pollution as closely as oil spills do.
