Why is stormwater runoff an issue?
Uncontrolled stormwater runoff has many cumulative impacts on humans and the environment including: Flooding – Damage to public and private property. Eroded Streambanks – Sediment clogs waterways, fills lakes, reservoirs, kills fish and aquatic animals. Widened Stream Channels – Loss of valuable property.
What are the causes and impact of stormwater pollution?
Stormwater impacts Stormwater running over rural land or from our catchment towns can pick up a range of pollutants: dissolved chemicals from various sources including pesticides and herbicides. waste from livestock and pets. sewerage and effluent from falling onsite wastewater treatment systems.
What are 2 examples of best management practices?
- Use Fertilizers Wisely.
- Apply Pesticides Wisely.
- Use Landscaping Practices that Prevent Erosion.
- Wash Your Vehicle Wisely.
- Dispose of Pet Waste.
- Use and Dispose of Household Chemicals Safely.
- Evaluate Existing Roads.
- Proper Planning of Roads.
How does stormwater impact the environment?
Stormwater runoff can cause a number of environmental problems: Fast-moving stormwater runoff can erode stream banks, damaging hundreds of miles of aquatic habitat. Stormwater runoff can push excess nutrients from fertilizers, pet waste and other sources into rivers and streams.
How can storm drain pollution be prevented?
Start with doing one of the actions on the following top 10 list:
- Maintain your car or truck.
- Wash your car at a commercial car wash rather than in the street or in your driveway.
- Drive less.
- Cut down on fertilizers, pesticides and herbicides.
- Remove part or all of your lawn.
What are the three types of water pollutants?
Types of Drinking Water Contaminants
- Physical contaminants primarily impact the physical appearance or other physical properties of water.
- Chemical contaminants are elements or compounds.
- Biological contaminants are organisms in water.
What are stormwater best management practices?
Stormwater Best Management Practices (BMPs) can be used to mitigate the effects of urban development by retaining large volumes of stormwater runoff and treating runoff to remove pollutants.
What is stormwater runoff and why is it important?
Stormwater runoff is generated from rain and snowmelt events that flow over land or impervious surfaces, such as paved streets, parking lots, and building rooftops, and does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams, lakes, and coastal waters.
What are the limitations of traditional stormwater management approaches?
Traditional stormwater management approaches that rely on peak flow storage have generally not targeted pollutant reduction and can exacerbate problems associated with changes in hydrology and hydraulics.

What are stormwater controls and why are they important?
The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams, lakes, and coastal waters. To protect these resources, communities, construction companies, industries, and others, use stormwater controls, known as best management practices (BMPs).
