Runoff from impervious surfaces
WebbIn turn, polluted runoff can have a direct impact on drinking and residential water quality. Increased stormwater runoff – along with impermeable surfaces in urban areas – can further lead to significant property damage and floods. This is why, over the past decade, stormwater management efforts have focused on improving the runoff’s quality. Webb7 juli 2024 · Stormwater Runoff and Impervious Surfaces. Perhaps the most defining characteristic of urban streams is the increased amount and rapidity of stormwater or surface runoff to those systems.
