Which of the following is NOT a method of well development?

• A. Chemical treatment
• B. Over pumping
• C. Rotary drilling
• D. Air surging

Answer: (C)

Rotary drilling is not considered a method of well development; rather, it is a technique used for drilling a borehole to create the well itself. Well development refers to the processes that enhance well performance after it has been drilled, ensuring that it can yield water effectively. Techniques like chemical treatment, over pumping, and air surging are all employed after the initial drilling to improve the well's flow rate and overall efficiency. Chemical treatment can remove fine materials that can clog the well, over pumping can help to stabilize the water level and clear obstructions, and air surging involves using compressed air to disturb sediments and enhance water flow. These methods are focused on optimizing the well's operational capacity, while rotary drilling serves the primary purpose of making the well itself, establishing the structure from which water will be extracted.
