What type of wells are usually categorized as shallow?

Water table wells are categorized as shallow because they are constructed to tap into the water table, which is the upper surface of the saturated zone of soil or rock where the pores are filled with water. This depth is typically within the range of a few feet to around 30 feet, depending on the local geological conditions and the amount of rainfall.

In contrast, artesian wells access water that is pressurized and found in confined aquifers, often located at greater depths. Spring wells are also relatively shallow, but they specifically occur at the point where groundwater flows naturally to the surface, often needing geological conditions that might not always qualify as shallow. Deep wells, as the name suggests, extend far below the surface and reach groundwater at much greater depths than typical shallow wells.

Understanding these distinctions is crucial for water resource management and ensures proper well construction and usage in line with local guidelines and best practices.
