Which of the following is the BEST example of point source pollution?

Question

BlackTom AI · Accepted Answer

The question asks for the BEST example of point source pollution, so we need to identify a pollution source that is single, identifiable, and controllable at its origin.
Option 1: Runoff from agricultural farm fields in the Salinas Valley. This is a classic nonpoint source example because the pollution originates from many diffuse locations across a landscape and is not traceable to a single discharge.
Option 2: Discharge from Santa Cruz County wastewater treatment plant. This fits the definition of point source pollution very well, as it is a specific, identifiable outlet (the treatment plant) where treated or untreated wastewater is released into a water body.
Option 3: Airborne nutrients and pesticides from a local farm. Although impactful, this is an atmospheric pathway and not a single, discrete discharge point to water, so it is not a point source pollutant; it’s more characteristic of nonpoint or atmospheric deposition scenarios.
Option 4: Diffuse groundwater pollution from an unknown source. By its nature, this is diffuse and not traceable to a specific discharge point, making it nonpoint source pollution rather than point source.
In summary, the clearest hallmark of a point source is a single, identifiable discharge pipe or outlet, which is precisely what option 2 describes. The other options describe diffuse or atmospheric pathways consistent with nonpoint source pollution.
