stormwater runoff
Stormwater runoff occurs when rainwater or melted snow flows over surfaces like roads, parking lots, and rooftops instead of soaking into the ground. This runoff can carry pollutants such as oil, chemicals, and debris into nearby rivers, lakes, and streams, affecting water quality and aquatic life.
Managing stormwater runoff is essential for preventing flooding and protecting the environment. Techniques like rain gardens, permeable pavement, and retention basins can help absorb and filter the water, reducing the amount of pollution that enters natural water bodies. Proper management also supports groundwater recharge and maintains healthy ecosystems.
