America's number one source of water pollution comes from suspended solids like soil, silt and debris.
|DO ||DON'T |
|Be on the lookout for soil, debris and chemicals leaving construction sites in stormwater runoff, and report poorly managed sites. |
Sweep up dirt and soil.
Cover dirt stockpiles in your driveway or move the piles to non-paved areas if the weather forecast predicts rain.
Cover topsoil piles and mulch to prevent it from blowing or washing away.
|Don't hose off pavement, which washes pollutants like dirt and soil into storm drains. |
Don't make piles of sand or soil in areas where they are likely to be washed into storm drains.
Suspended Solids Effects (Soil, Silt, Debris)
- Inhibits light from reaching aquatic plants, making it difficult for them to grow.
- Can destroy underwater habitats.
- Clogs gills and siphons of underwater animals.
- Impedes fish migration.
- Increases water temperature, which reduces the maximum quantity of dissolved oxygen for aquatic life.
- Causes increases in spending on the storm sewer system when it is clogged with excessive amounts of dirt.
