The definitions of shallow wells, normal depth wells, and deep wells can vary depending on the specific situation, the construction of the well, and geological conditions. In general, the terms mean:
Shallow Well: A shallow well is typically a dug or bored well that obtains water from a shallow source, which makes it more susceptible to surface contamination. The depth of a shallow well can vary, but it is often associated with wells that have a depth of 20 feet or less.
Normal Depth: A normal depth well does not have a specific definition and can vary depending on factors such as soil type and the depth of the aquifer. For example, in some areas, a well that taps into an aquifer at a depth of 70 feet may be considered a normal depth well, while in other areas, a well at 20 feet may be considered normal.
Deep Well: A deep well is typically a well that is drilled into the ground and reaches greater depths. The depth of a deep well can vary, but it is often associated with wells that are deeper than 100 feet. Deep wells are often used to access water from deeper aquifers and may have different construction requirements compared to shallow wells.
It’s important to note that these definitions can vary depending on the region and specific circumstances, so it’s always best to consult with local experts or authorities for accurate information regarding well depths in a specific area.
