4 Types Of Pollutants in Stormwater & Ways to Respond

In a majority of cases stormwater runs off roofs, driveways, and streets into nearby trenches or bodies of water. Pollutants in stormwater can end up in local waterways and impact fish, birds, and other aquatic life.

If your home is filled with water due to a severe storm, it is important to be familiar with the contaminants in water to ensure you are able to protect your health. A large number of everyday activities lead to pollution in stormwater. To help you avoid health issues, we have created an outline of various types of contaminants in water and ways to respond to water damage.

What Is Urban Stormwater Runoff?

Urban stormwater runoff is a term used to describe rainwater and melting snow that flow across several types of landscapes and surfaces.

If not managed properly, urban stormwater can overwhelm a city’s drainage system and surrounding bodies of water, causing long-term environmental damage. Stormwater can cause flooding, erosion, and pollution leading to large environmental, health, and economic issues.

How Stormwater Collects Contaminants

Excessive rain or snow creates high levels of water throughout the year. This stormwater moves across impermeable surfaces such as asphalt and concrete and collects trash, debris, and other pollutants.

Urban and suburban areas have a higher likelihood of stormwater runoff because of the paved road to dirt-road ratio. Additionally, harmful chemicals and pesticides in city environments can bind to leaves, branches, and other materials, contributing to a harmful environment.
