A confined aquifer is curtained by an impermeable layer of rock or substrate. If a confined aquifer moves downward from its recharge zone, groundwater can become pressurized. This, in turn, will create artesian wells that flow freely without the necessity of a pump and rise to a better eleva...
A deep well that passes through impermeable rock or sediment and reaches water that is held under pressure in a confined aquifer. In aquifers of this type, the water in the lower regions is trapped between two layers of impermeable rock and cannot rise to the level of the water table in ...
Examples of the use of transient electromagnetic soundings for three ground-water exploration problems in sedimentary aquifers are given. The examples include: (1) estimating depths to water table and bedrock in an alluvium-filled basin, (2) mapping a confined fresh-water aquifer in bedrock ...
Another sounding identified a very low-resistivity layer (less than 10 ohm-m) at 5-6 m depth about 1 km southwest of the north landfill - this may represent leachate contamination of a shallow confined aquifer. Electrically conductive zones, also possibly indicating...

5. Conclusions In general, groundwater quantity issues are most prominent in the central sands region of central Wisconsin and heavily populated parts of northeastern and southeastern Wisconsin that draw from confined aquifers. Some regions, such as the municipalities near Lake Michigan, are fortunate ...
