How Storm Drains Carry Pollutants to Rivers and Oceans - Environmental Impact Diagram #88231 (License: Personal Use)

The image depicts a cross-sectional illustration of urban stormwater runoff: rainwater carrying pollutants like oil, trash, and chemicals flows over pavement into a storm drain inlet, then travels through an underground pipe and discharges untreated into a creek or river. A yellow fire hydrant sits on the sidewalk above, emphasizing the proximity of infrastructure to natural systems. Arrows and labels clarify the path of contamination from surface to aquatic environment.

Used in environmental education, municipal sustainability pages, EPA outreach materials, and school curricula to illustrate nonpoint source pollution and the importance of proper waste disposal and green infrastructure. Matches user intent for understanding stormwater management and watershed protection.
