What is the required storage/dispensing setback from private wells?

• A. 400 feet
• B. 75 feet
• C. 100 feet
• D. 0 feet

Answer: (B)

Pesticide storage and dispensing areas must be kept a safe distance from private wells to protect drinking water from contamination from spills, leaks, or pesticide movement through soil or runoff. This buffer minimizes the chance that any pesticide could reach the well and enter the water supply.

The required distance is 75 feet, which provides a practical protection zone while still allowing reasonable access for handling and dispensing. If you ever can’t meet this distance, you’d need to implement additional safeguards such as secondary containment, proper labeling and storage practices, spill cleanup readiness, and, if necessary, relocate the storage area or obtain guidance from the regulator. Distances like 0 feet would pose a risk, and larger distances are not the standard requirement in this scenario.
