This winter brought much needed rain to the Pedlar River watershed. With rain comes runoff, and with runoff comes sediment. Sediment is the fancy word for the loose sand, clay, silt and other soil particles that are dislodged from the land by rainwater and transported by stormwater runoff towards bodies of water. While runoff and erosion are natural processes, human activities on the land can drastically increase the rate at which sediment enters our waterways, making sediment pollution the #1 type of water pollution in our region of the James River watershed. (State of the James Report Card 2021, James River Association). Our local waterways have been looking cloudy after the big rains this winter. Sediment is what makes that cloud in the water. The color of that cloud varies depending on what kind rock, soil, and clay runs off the land or makes up the stream bottom and sides. In the Pedlar River, the sedimentation cloud often looks orange, like our clay soils. Activities that expose soil are the main causes of sediment pollution in the Pedlar River watershed–such as logging, removing trees and shrubs from steep slopes and near streams, farming practices such as tilling, use of pesticides and fertilizers near streams, unprotected streambanks in fields and livestock pastures, and construction practices that do not follow Best Management Practice guidelines. Here’s the quick dirt on why we need soil to stay on the ground and out of the water, plus info about how you can make sure your property keeps its sediment to itself. Please, read on and do your part to protect our streams and rivers. Sediment is considered a pollutant because it degrades the quality of water for drinking, wildlife and the land surrounding streams in the following ways: It clouds the water, preventing animals from seeing food and harming aquatic vegetation. In streams, sediment disrupts the natural food chain by destroying the habitat where the smallest stream organisms live–organisms that are food for fish. And sediment can clog fish gills, reducing resistance to disease, lowering growth rates, and affecting fish egg and larvae development. Sediment increases the cost of treating drinking water and can result in odor and taste problems. It fills up storm drains and catch basins to carry water away from roads and homes, which increases the potential for flooding. Nutrients transported by sediment can activate blue-green algae that release toxins and can… Continue reading
