What is aquifer system.
The Gulf Coast Aquifer is a major aquifer paralleling the Gulf of Mexico coastline from the Louisiana border to the border of Mexico. It consists of several aquifers, including the Jasper, Evangeline, and Chicot aquifers, which are composed of discontinuous sand, silt, clay, and gravel beds. The maximum total sand thickness of the Gulf Coast ...
The simple aquifer shown in Figure 6 is termed an unconfined aquifer because the aquifer formation extends essentially to the land surface. As a result, the aquifer is in pressure communication with the atmosphere. Unconfined aquifers are also known as water table aquifers because the water table marks the top of the groundwater system. Local aquifer (by name) -- For groundwater sites, you can also select the local aquifer that the wells are completed in.

On the basis of permeability, this system is divided into the Upper and Lower Floridan aquifers, which are separated by a less permeable limestone sequence …
A principal aquifer is defined as a regionally extensive aquifer or aquifer system that has the potential to be used as a source of potable (drinkable) water. For study or mapping purposes, aquifers are often combined into aquifer systems. A two-dimensional map representation of the principal aquifers of the Nation is shown below.
Cause. Fine-grained sediments (clays and silts) within an aquifer system are the main culprits in land subsidence due to groundwater pumping. Fine-grained sediments are special because they are composed of platy grains (imagine the shape of dinner plates). When fine-grained sediments are originally deposited, they tend to be deposited in random ...

It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers. Groundwater is used for drinking water by more than 50 percent of the people in the United States, including almost everyone who lives in rural areas.
The Floridan aquifer system is composed of two main aquifers: the Upper Floridan aquifer and the Lower Floridan aquifer. These aquifers are separated by sediments that range from low-permeability clays in the panhandle (Bucatunna Clay) and low-permeability dolomites and gypsiferous anhydrite in west-central Florida to permeable limestones along ...
These aquifers are also known as water table aquifers. They receive recharge directly from the infiltration of rainfall and surface water. Confined aquifers are those that are covered (confined) by an impermeable or semi-permeable layer of rock. Confined aquifers are not directly recharged by vertical infiltration.

Where groundwater can move rapidly, such as through gravel and sandy deposits, an aquifer can form. In an aquifer, there is enough groundwater that it can be pumped to the surface and used for drinking water, irrigation, industry, or other uses. And once an aquifer is contaminated, it's notoriously difficult to remediate. Additional resources: The U.S. Water Monitor is a daily "water health" report that summarizes federal water information.2. Classification of aquifers. Aquifers are generally been classed into two main categories namely confined aquifer and unconfined aquifers. 2.1. Confined aquifers. Confined Aquifers are those bodies of water found accumulating in a permeable rock and are been enclosed by two impermeable rock layers or rock bodies.
