Rainwater Runoff Illustration - Stormwater Pollution & Urban Drainage #1997292 (License: Personal Use)

This stylized illustration uses a single raindrop to depict three layers of urban stormwater dynamics: the upper layer shows rainfall hitting pavement where a boot steps, the middle features a cheerful mouse in a paper boat under a pink umbrella symbolizing clean surface runoff, and the lower right reveals dark, polluted water entering a storm drain grate. The contrast highlights how impervious surfaces and everyday activities contribute to water pollution.

Used on environmental nonprofit websites, municipal stormwater management pages, or educational resources about watershed protection; targets users seeking to understand nonpoint source pollution and advocate for green infrastructure.
