Which of the following is a point-source pollution?A. Wastewater Treatment PlantB. City StreetsC. Rural HomesD. Animal FeedlotE. Suburban Development

The answer is A. Wastewater Treatment Plant.

Point-source pollution refers to contaminants that enter the environment through a single, identifiable source. In this case, a wastewater treatment plant is a clear, identifiable source of pollution, making it a point-source pollution.

Here's a step-by-step explanation:

1. Understand the term: Point-source pollution is any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack.

2. Apply the term: Now, look at the options given. We need to find an option that fits the definition of point-source pollution.

3. Evaluate the options:

   • Wastewater Treatment Plant: This is a single, identifiable source of pollution. The plant processes wastewater and in the process, can release pollutants into the environment.
   • City Streets: These are not a single, identifiable source. Pollution from city streets comes from many different sources, like cars, litter, etc.
   • Rural Homes: These are not a single, identifiable source. Pollution from rural homes can come from various sources like septic tanks, litter, etc.
   • Animal Feedlot: This could be considered a point-source pollution if it's a large, concentrated animal feeding operation. However, it's not as clear-cut as a wastewater treatment plant.
   • Suburban Development: This is not a single, identifiable source. Pollution from suburban development can come from construction, cars, homes, etc.

4. Choose the best answer: Based on the evaluation, the best answer is A. Wastewater Treatment Plant.
