Many people believe that trash enters rivers only through illegal dumping and littering, but in reality, there are many other pathways.
Trash created on land can still end up in rivers even when it is properly disposed of. The primary ways trash enters waterways include stormwater runoff, wind transport, illegal dumping, and sewer overflows, all of which move litter from streets, parks, and landfills into rivers and streams. During rainfall, water flows over streets, parking lots, and sidewalks, collecting litter and carrying it into storm drains that often discharge directly into local waterways.
Wind can also transport lightweight materials such as plastic bags, food wrappers, and Styrofoam from open trash bins and landfills into rivers, lakes, and streams. In some areas, heavy rainfall overwhelms sewage systems, causing sewer overflows that release untreated water and debris into rivers. Urban environments worsen this problem because paved surfaces increase runoff speed, allowing trash to be carried into waterways more quickly. Poorly managed trash bins that are overfilled or uncovered further increase the likelihood of debris escaping. Even small items, such as cigarette butts, can become plastic pollution in our river. This mismanaged waste harms water quality, wildlife, and recreational areas.
Volunteer with us and learn how to use less plastic, prevent litter, and improve the way we manage all types of waste and stormwater.
