Stormwater Pollution Prevention Tips

Household Pollutants

• Common household cleansers and solvents often contain unknown ingredients that not only can be harmful to humans, but can be poisonous to plants and wildlife. Always select the least toxic product and use water-based cleaners whenever possible. Phosphates alter water chemistry and promote algae blooms. As a result, many manufacturers now offer phosphate-free detergents. Be sure to dispose of unused cleaning products and household chemicals at your local hazardous waste collection center. Never pour them down the drain or on the ground.

Landscaping and Gardening

• Creative landscaping that takes stormwater into consideration is the best solution to runoff problems. Walk the perimeter of your property during, or shortly after, a heavy rain and look for areas that have water running into streets or onto sidewalks. Using plants, gravel or a combination of both in these areas will slow the flow of water and allow it to seep into the ground. Incorporate wood decks, gravel or interlocking bricks and stones rather than cement whenever possible to increase percolation. It's best to limit the use of high-maintenance areas, such as green lawns. If you choose the keep a lawn area, incorporate landscaping wales. These are low dips in the lawn that allow water to collect and percolate rather than flowing off the grass.

Outdoor Construction and Remodeling

• Construction and remodeling projects present special issues in stormwater control and pollution prevention. Exposed soils and the addition of impervious building materials will likely contribute to excessive runoff and erosion problems. Fiber rolls or silt fence materials can be used to protect overturned soil prone to erosion during the construction process. Stacked bags of gravel or sand around storm drains will absorb eroded sediments while letting water pass through. Temporary seeding can be used to stabilize soils in areas that will be exposed for longer periods.
