Soil erosion rates accelerate dramatically, impacting water quality in streams and rivers.

Removing vegetation, grading, and exposing bare soil on construction sites makes runoff much more erosive. That runoff carries large amounts of sediment (turbidity), and often attached pollutants (nutrients, metals, oils), into nearby waterways, degrading habitat and water quality.
