What is the required storage/dispensing setback from public surface water supplies?

• A. 75 feet
• B. 100 feet
• C. 400 feet
• D. 200 feet

Answer: (C)

Protecting public surface water supplies from pesticide contamination relies on keeping storage and dispensing activities well away from the water source. A larger setback reduces the chance that spills, leaks, or runoff during rain events can carried pesticides into streams, lakes, or reservoirs. The required distance is 400 feet, which provides a substantial buffer to help prevent contamination. Smaller distances like 75, 100, or 200 feet don’t offer as much protection against runoff or accidental spills, especially under varying weather, terrain, and pesticide properties. Follow this 400-foot rule to help safeguard drinking water, unless local regulations allow a different approved method.
