$$60\% + (0.5 \times 40\%) = 80\%$$

Question 1

Which of the following is a primary purpose of Best Management Practices (BMPs) in urban environments?

Accepted Answer

To reduce nonpoint source (NPS) pollution by managing stormwater infiltration and runoff

Question 2

A rain garden is designed to improve water quality by which of the following mechanisms?

Accepted Answer

Promoting infiltration of runoff and filtering pollutants through soil and vegetation

Question 3

Which BMP is most appropriate for reducing runoff from a residential driveway while maintaining vehicle access?

Accepted Answer

Porous pavement

Question 4

Which equation best represents the treatment train approach for BMPs, where multiple practices are combined for maximum effectiveness?

Accepted Answer

$$x + y = 80\%$$ removal$

Question 5

A city wants to reduce NPS pollution from a parking lot. Which BMP would be LEAST effective?

Accepted Answer

Increasing the area of traditional asphalt pavement

Question 6

Which of the following is a common misconception about infiltration trenches?

Accepted Answer

They are effective even if the soil is compacted and impermeable

Question 7

A school plans to install a BMP to treat runoff from its playground. Which step should be included in the planning process?

Accepted Answer

Creating a field checklist and documenting the site with sketches

Question 8

Which BMP is most likely to be regulated by the EPA's Underground Injection Control Program?

Accepted Answer

Infiltration trench with subsurface drainage

Question 9

A modular pavement system is designed to:

Accepted Answer

Support vehicle loads while allowing infiltration of surface water

Question 10

Which BMP would be most effective for treating runoff from agricultural fields?

Accepted Answer

Vegetated buffer strips

Question 11

A city is considering two BMPs: a wetland and a retention pond. Which factor should be compared to determine feasibility?

Accepted Answer

The cost, pollutant removal efficiency, and land requirements

Question 12

Which of the following is NOT a category of BMPs for stormwater management?

Accepted Answer

Chemical precipitation practices

Question 13

A homeowner wants to reduce runoff from their property. Which BMP would be most suitable?

Accepted Answer

Installing a rain garden

Question 14

Which BMP is specifically designed to temporarily store runoff before allowing it to infiltrate into the soil?

Accepted Answer

Infiltration basin

Question 15

If a BMP removes 60% of pollutants and is followed by another BMP that removes 50% of the remaining pollutants, what is the total percent removal?

Accepted Answer

$$60\% + (0.5 	imes 40\%) = 80\%$$

Question 16

Which of the following is a real-world application of porous pavement?

Accepted Answer

Parking lots with modular blocks that allow water infiltration

Question 17

Why is it important to keep the soils on the floor and side slopes of an infiltration basin uncompacted?

Accepted Answer

To maximize the rate of water infiltration

Question 18

Which BMP would be most effective for treating runoff from a low-volume traffic access road?

Accepted Answer

Modular pavement blocks

Question 19

A city wants to maximize pollutant removal from stormwater using multiple BMPs. Which strategy should they use?

Accepted Answer

Combine several BMPs in a treatment train approach

Question 20

Which of the following is a benefit of vegetated buffer strips in agricultural settings?

Accepted Answer

They filter pollutants and promote infiltration
