Ready to play a game of “Pervious or Impervious”? Here’s how: brush up on your knowledge of pervious and impervious surfaces below, and then watch the video to see how many you can guess correctly!
💧PERVIOUS surfaces decrease the volume and speed of stormwater runoff by allowing water to seep into the ground. These surfaces also help filter out many pollutants before stormwater reaches larger waterways.
💧💧IMPERVIOUS surfaces increase the volume and speed of stormwater runoff because water is not able to seep into the ground. Impervious surfaces can erode stream beds and reduce water filtration, leading to more pollutants and sediment entering waterways.
