What is the difference between 'artesian' and 'artesian well'?

Everything is competitive in the market. The people purchase their goods not only home country, but also abroad. Globalisation measured by money value and value of materials going to purchase by the people of the world.

An artesian aquifer is a confined aquifer containing groundwater under positive pressure. This causes the water level in a well to rise to a point where hydrostatic equilibrium has been reached. A well drilled into such an aquifer is called an artesian well.

Artesian is of water rising to the surface under its own hydrostatic pressure.

CONFINED means to restrict to keep within boundary in a limited space. I think the answer is right is Artesian.

Confined aquifers: when the water-bearing bed occurs between two impermeable layers. This type of aquifer can hardly be contaminated.

Unconfined aquifer: when only the lower portion of the aquifer has impermeable material. Hence this type of aquifer is connected to the surface and can be easily contaminated.

A basin or trough-like structure with steep sides.

There must be a catchment area which gives high rainfall.

The aquifer must be confined i.e. occur between two impermeable layers.

The permeable strata (aquifer) should be exposed at the surface.

I think confined is the correct option.

An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer is a trapped water, surrounded by layers of impermeable rocks or clay, which applies positive pressure to the water contained within the aquifer.
