Which of the following is NOT a type of well?

The correct answer is "Blasted" because it is not a recognized type of well in conventional water well construction terminology.

Drilled wells are created using a drilling rig that bores a hole into the ground to access groundwater. This method allows for precise placement and can reach deep aquifers. Jetted wells utilize high-pressure water jets to penetrate soil and rock, often used in softer soil conditions. Dugout wells, also known as dug wells, are excavated by hand or machine and typically have a larger diameter, reaching water closer to the surface.

In contrast, the term "blasted" does not correspond to a standard well construction method. Instead, blasting is a technique often used in mining or construction to remove large quantities of rock or to create space for various purposes, but not specifically for water well creation. Thus, "Blasted" is not a recognized type of well, making it the correct choice in this context.
