What is the mixing and loading setback distance for All private water wells?

• A. 50 feet
• B. 25 feet
• C. 400 feet
• D. 75 feet

Answer: (D)

Mixing and loading pesticides near drinking water sources is tightly controlled to protect the water you drink. For private wells, a minimum distance of 75 feet between the well and the place where you mix or load pesticides is required. This 75-foot buffer reduces the chance that spills, leaks, or spray drift will reach the well through runoff or groundwater movement. Measure from the wellhead to your mixing/loading area, and ensure the site is well-drained and clearly separated from the well. If the site can’t meet this distance, look for compliant alternatives—such as relocating the operation to a compliant site or using approved containment and methods—before proceeding.
