Unconfined Aquifers
Unconfined aquifers are underground layers of water-bearing permeable rock or soil that are directly connected to the surface through empty spaces or pores. Since they are not sealed above, they can be recharged by rainfall or surface water seeping down from above. The water level in these aquifers can fluctuate with natural conditions and human activity. They are accessible through wells and are an important source of drinking water. Unlike confined aquifers, they are more vulnerable to pollution because they are exposed to surface contaminants.
