Question 1

Which stormwater management approach mimics natural hydrology by infiltrating, filtering, and evapotranspiring runoff near its source?

Accepted Answer

Low Impact Development (LID)

Answer

Low Impact Development uses distributed, small-scale practices like bioretention, permeable pavement, and green roofs to manage stormwater close to the source.

Question 2

Under CWA Section 404, which agency issues permits for dredge and fill activities in waters of the United States?

Accepted Answer

U.S. Army Corps of Engineers

Question 3

What is a groundwater recharge zone?

Accepted Answer

A zone where water infiltrates from the surface to replenish an aquifer

Answer

A groundwater recharge zone is an area where precipitation or surface water infiltrates through permeable soils and rock to replenish an underlying aquifer.

Question 4

Which water quality parameter measures the amount of oxygen required by microorganisms to decompose organic matter in water?

Accepted Answer

Biochemical oxygen demand (BOD)

Answer

BOD measures the amount of oxygen consumed by biological decomposition of organic matter over a standard five-day period at 20°C.

Question 5

What is the primary cause of saltwater intrusion in coastal aquifers?

Accepted Answer

Excessive groundwater pumping that reduces freshwater head pressure

Answer

Excessive groundwater extraction lowers the freshwater head in coastal aquifers, allowing denser saltwater to migrate landward and contaminate the aquifer.
