Stormwater Runoff Pollution Management

The video discusses the challenges of managing runoff pollutants in environmental science and engineering. It explains the natural hydrologic cycle and how human activities, like adding impervious surfaces, increase runoff and introduce various pollutants. These pollutants, including sediments, nutrients, and chemicals, can originate from non-point and point sources. The video also covers strategies to manage runoff, such as using biological and vegetative buffers, and highlights the importance of environmental engineering in mitigating these issues.

What is a runoff pollutant?

• Water that evaporates into the atmosphere

• Water that is used for irrigation

• Water that moves over the land surface

• Water that infiltrates into the ground

Which of the following is NOT a type of pollutant found in stormwater runoff?

• Erosion

• Solar radiation

• Sediments

• Metals

What is a non-point source pollutant?

• Pollutants that are always beneficial

• Pollutants that only affect air quality

• Pollutants that are widespread and not from a single source

• Pollutants from a single, identifiable source

Why is temperature considered a pollutant in stormwater runoff?

• It can raise water temperature, affecting ecosystems

• It can increase water acidity

• It can cause water to freeze

• It can decrease water flow

How can nutrients in runoff affect aquatic ecosystems?

• They can cause algal blooms

• They reduce water temperature

• They increase water clarity

• They prevent erosion

What is a common source of point source pollution?

• Landscaping and lawn care

• Rainfall

• Natural springs

• Evaporation

Which activity is NOT typically associated with point source pollution?

• Street cleaning

• Cloud formation

• Vehicle maintenance

• Pest control

What is a strategy used to manage stormwater runoff?

• Increasing water temperature

• Reducing rainfall

• Using biological buffers

• Increasing impervious surfaces

What is the purpose of vegetative buffers in managing runoff?

• To increase soil erosion

• To reduce plant growth

• To capture and slow down pollutants

• To increase water flow speed

Which of the following is a large-scale project for managing runoff?

• Street cleaning

• Bio-retention basins

• Car washing

• Pesticide application
