There are several ways our stormwater runoff causes pollution to our waterways. One of the best ways to combat this is to be aware of those major pollutants and to take part in making sure those pollutants are minimized as much as possible. Solid waste is the most noticeable and preventable contaminant. To do your part make sure all solid waste is contained for pick-up and join efforts to keep our communities litter-free. Sediment occurs when stormwater washes soil into existing streams causing an imbalance of nutrients, impacted habitats and altered streamflow. An easy way to prevent this from your household or business is to slow down the runoff by adding mulch or rock to your landscaping. Nutrient rich materials (fertilizers), Pathogens (pet/septic waste), and toxic materials (oil spills, etc.)  are all other factors to consider when trying to eliminate the harmful effects of stowmwater runoff.
