What is storm water pollution?

Stormwater pollution refers to the contamination of rainwater or melted snow as it flows over surfaces such as roads, parking lots, and agricultural fields, picking up pollutants like oil, heavy metals, pesticides, and debris. This polluted runoff can enter storm drains and water bodies without treatment, adversely affecting aquatic ecosystems, drinking water supplies, and public health. Effective management practices, such as green infrastructure and proper drainage systems, are essential to mitigate stormwater pollution and protect the environment.
