The primary concern related to well interference is overlapping drawdown effects. This phenomenon occurs when multiple wells are in close proximity to each other and are extracting groundwater from the same aquifer. As each well draws water, they create a cone of depression in the water table around them. When two or more wells operate simultaneously, the drawdown effects can overlap, leading to a situation where the total drawdown in the aquifer exceeds what would occur if the wells were operating independently.

This overlapping effect can have several negative implications, such as reduced water availability for each well, decreased efficiency of water extraction, and increased costs for water users. Furthermore, it can also lead to a decline in water quality if the drawdown pulls contaminants toward the wells or causes changes in groundwater flow patterns that disturb the natural filtration processes.

In contrast, increased water temperature, soil erosion, and surface runoff may be important considerations in agricultural practices and environmental management, but they do not directly relate to the concern of well interference in terms of water extraction and aquifer management.
