Water, Air, Energy, And Waste Management For Environmental Sustainability Practice Test

Stormwater Best Management Practices are about keeping rainfall on the landscape where it falls, slowing it down, and removing pollutants as it moves through the system. Green roofs intercept rainfall on rooftops and create a shallow, vegetated layer that stores water, increases evaporation, and reduces how much runoff leaves the building. Bio-retention areas and rain gardens use engineered soils and plants to infiltrate water and filter nutrients and sediments as runoff passes through. Retention and detention basins provide temporary storage, spreading out the release of runoff so peaks are dampened and pollutants have more time to settle or be treated. Together, these practices actively manage runoff at the source and improve water quality, which is the essence of BMPs for stormwater. The other options describe activities more related to drinking-water treatment or large-scale infrastructure rather than on-site stormwater management.
