aquifer. A water table aquifer is an example of an unconfined aquifer. A confined aquifer is trapped below an upper confining layer of rock, clay or shale. When a well is drilled into a confined aquifer, the water level in the well rises above the upper boundary of the aquifer.
Thirstin Builds an Aquifer K-3 AQUIFER IN A CUP (AQUIFER ON THE GO) BACKGROUND: Many communities obtain their drinking water from underground sources called aquifers. Water suppliers or utility officials drill wells through soil and rock into aquifers for the ground water contained therein to supply the public with drinking water.
Earth’s surface. Groundwater percolates through the spaces in and around these materials, sometimes forming underground reservoirs of water known as aquifers. Some aquifers are small, while others span tens of thousands of square miles. The Middle Claiborne Aquifer is one of the latter. It underlies portions of eight States in the Missis-

landfills were often sited over aquifers or close to surface waters and in permeable soils with shal-low water tables, enhancing the potential for leachate to contaminate ground water. Closed landfills can continue to pose a ground water con-tamination threat if they are not capped with an impermeable material (such as clay) before closure

3. Ground Water Resources Availability: Rainfall is the major source of ground water recharge in India, which is supplemented by other sources such as recharge from canals, irrigated fields and surface water bodies. A major part of the ground water withdrawal takes place from the upper unconfined aquifers, which are also the active
water supply, primarily from bedrock aquifers (shales and sandstones).
