What is the mixing and loading setback distance for a Non Gravel Packed Public Well?

• A. 75 feet
• B. 400 feet
• C. 50 feet
• D. 250 feet

Answer: (D)

During mixing and loading, the distance kept from a water source is all about protecting drinking water. A non-gravel-packed public well has less natural filtration in the surrounding soil, so contaminants can travel more readily toward the well if spills, leaks, or drift occur. Because of this, the regulating rule sets a substantial buffer to reduce the chance that anything handled during mixing and loading reaches the well. The required minimum distance in this case is two hundred fifty feet, which helps ensure any potential contamination has enough roadblock time to dissipate before it could affect the public water supply. Smaller setbacks would not provide the same level of protection, while other scenarios (like gravel-packed wells or different water sources) may call for different distances.
