According to the EPA, soil is the number one pollutant in waterways, and if it is transported offsite it can fill up small tributaries and streams and move on until it reaches the mouths of rivers, bays, and other waterways.
It is important to control erosion first, and then contain the silt and sediment that does erode. That is why we recommend a number of best management practices (BMPs) for erosion control on slopes, embankments and landscape formations that border streams, rivers or lakes.
