Which of the following factors can influence the effectiveness of a water well?

The effectiveness of a water well is closely tied to both the depth of the well and the composition of the surrounding soil. The depth of the well determines how far the water must be drawn from the aquifer and can impact the amount of water available, as well as the pressure and quality of the water. Deeper wells may access more reliable water sources during dry seasons but can incur higher costs for drilling and maintenance.

Additionally, the surrounding soil composition affects water quality and flow rates. Different soil types have varied permeability, which can influence how quickly water can be drawn from the well and how contaminants may enter the water supply. For instance, sandy soil allows for quick water flow, while clay can impede it, affecting how much water can be extracted and its cleanliness.

Other factors, while influential in broader environmental or operational contexts, do not directly affect the well's functionality in the same way. The location of nearby businesses, presence of urban areas, and weather conditions during the drilling process may impact water demand, surface runoff, or logistical considerations, but they do not influence the intrinsic effectiveness of the well itself as directly as the depth and soil composition do.
