Figure 4. 1 shows several aquifers and observation wells. The upper phreatic aquifer ( A) is underlain by two confined ones ( B and C) . In the recharge area，aquifer B becomes phreatic. Portions of aquifers A，B，and C are leaky，with the direction and rate of leakage deter...

The results showed that there were two types of aquifers, namely unconfined aquifers and unconfined aquifers. Related to this study, well 1 took water in the unconfined aquifers of 4 m depth. If the water kept taken for a long period, the quality and quantity of the water would be worse ...

There are three types of aquifers70. The upper shallow aquifer is located northwest of the coastal area, with a thickness varying from a few meters to 60 m. Second, the shallow aquifer, which has a thickness ranging from 10 m to more than 100 m71, contains saltwater pockets, particularly ...
Underground reservoirs are called aquifers. Groundwater gathers where the geology allows reservoirs to develop. Some aquifers are totally sealed, and some aren't. There are different types of aquifers. In some cases, they feed surfacewatersupplies and even release water in the form of springs. ...
Uptake of uranium (U) by secondary minerals, such as carbonates and iron (Fe)-sulfides, that occur ubiquitously on Earth, may be substantial in deep anoxic environments compared to surficial settings due to different environment-specific conditions. Yet, knowledge of U reductive removal pathways an...
