Where are filter strips typically located?

• A. Next to streams, ponds, and other water bodies
• B. In the center of fields
• C. Under the soil surface
• D. On rooftops

Answer: (A)

Filter strips are vegetated buffer zones placed along the edge of fields where they border streams, ponds, or other water bodies. Their job is to intercept and filter runoff from the field before it reaches the water, using grasses and other plants to slow flow, trap sediment, and absorb or degrade nutrients and pesticides. This location—right next to the water body—maximizes the strip’s ability to protect water quality and bank stability, since runoff passes through the vegetation as it enters the water. Placing them in the center of fields wouldn’t intercept runoff before it reaches water, placing them under the soil wouldn’t interact with surface runoff, and placing them on rooftops isn’t relevant to field drainage.
