Question

an artesian well draws water from what type of aquifer? perched aquifers confined aquifers unconfined aquifers bedrock aquifers

Explanation:

An artesian well is a well that taps into a confined aquifer. In a confined aquifer, the water is under pressure due to the layers of impermeable rock or clay (aquitards) above and below it. When the well is drilled into the confined aquifer, the pressure causes the water to rise in the well without the need for a pump. Perched aquifers are small, isolated aquifers above the main water table. Unconfined aquifers have no confining layer above them and are open to the atmosphere. Bedrock aquifers are aquifers within bedrock but the key characteristic of an artesian well is its connection to a confined aquifer.

Answer:

confined aquifers
