The adjacent aquifer area north of the Iao aquifer is the Waihee aquifer which extends north to Kahakuloa Stream.

The dike-impounded water body is found in the mountainous interior part of the aquifer. ... The general movement of fresh ground water in the Iao aquifer area is from the dike-impounded water body into the freshwater-lens system and then to the ocean (US Geological Survey Water-Resources Investigations Report 00-4223). Similar occurrences of ground water are expected in the Waihee aquifer area.

4. The Ogallala Aquifer Depletion
- www.iitap.iastate.edu
- The Ogallala Aquifer Depletion.
- The Ogallala Aquifer underlies approximately 225,000 square miles in the Great Plains region, particularly in the High Plains of Texas, New Mexico, Oklahoma, Kansas, Colorado, and Nebraska. The depth of the aquifer from the surface of the land, its reate of natural thickness, vary from region to region. The aquifer has long been a major source of water for agricultural, municipal, and industrial development.
- Use of the aquifer began at the turn of the century, and since World War II reliance on it has steadily increased. The withdrawal of this groundwater has now greatly surpassed the aquifer's rate of natural recharge. Some places overlying the aquifer have already exhausted their underground supply as a source of irrigation. ...
- The most recent High Planes-Ogallala Aquifer Regional Resources study was sponsored by the US Department of Commerce (DOC) and was released in mid-1982. ...
- Policies developed in response to depletion of the aquifer that may be technically and economically feasible must also be politically and socially acceptable. ...
- The rates of drawdown and recharge of the aquifer vary from one locale to another. ... This difference translates into varying degrees of concern about the depletion of the Ogallala Aquifer with, for example, Texas being more concerned than Nebraska (which happens to have the most favorable recharge rate of all areas throughout the region that overlays the aquifer). ...
- Is the drawdown a national problem? How concerned should national leaders be about the depletion of this aquifer? This question raises a dilemma for some of those immediately affected. While on the one hand there is interest within the states in generating national concern about the "problem," on the other hand, there is a strong desire to keep control of the aquifer and its management at the local and state levels. Because of the local variations in aquifer thickness, people in the region prefer local responses to local changes in the aquifer. ...
- The drawdown of the aquifer raises an important issue that permeates discussions about the social and political responses to a global warming: discounting the future. ...
- Are the policy measures implemented in response to the Ogallala Aquifer depletion applicable to changes in regional water supplies that may result because of projected changes in climate due to increasing CO2? The depletion of the aquifer represents a change in the water balance of the Great Plains region, as would the suggested impacts of global warming. ... By using the Ogallala Aquifer depletion as an analogue, scientists and policy makers can learn much about the process of evaluating and selecting socially acceptable policy responses to large-scale environmental issues. ...

- The Floridan aquifer is a confined artesian aquifer. ...
- Some hydrologists estimate that the total quantity of freshwater in the Floridan aquifer is more than one quadrillion gallons (That would be 15 zeros).
- Throughout central Florida, the Floridan aquifer lies at 100 to 200 feet beneath the surface. ... In the west coastal and the north-central areas, the Floridan aquifer is closer to the surface.
- The formations in the Floridan aquifer are predominantly made up of limestone (calcium carbonate), dolomite (calcium-magnesium carbonate) and limestone-dolomite mixtures. ...
- The rocks that make up the aquifer are easily dissolved by acidic rainwater. Portions of rock making up the aquifer have dissolved over thousands of years. ...
- The Floridan aquifer is replenished in a natural process called "recharge. " Recharge occurs when water seeps down from the surficial aquifer to the Floridan, directly into the Floridan where it is closer to the surface, or where sinkholes have broken through the Floridan's confining layer. ... However, most water is discharged when people drill wells to withdraw water from the aquifer.

11. Arthur testifies regarding High Plains aquifer
- www.txfb.org
- High Plains aquifer .
- The proposed Senate bill, which calls for a federal study of the Ogallalla, or High Plains, aquifer, would expand federal power over groundwater. Speaking to members of the House Resources Committee, and the Water and Power Subcommittee, Arthur, a producer who grows cotton and grain sorghum on 3,781 acres of farmland in that area, irrigates his crops from the High Plains Aquifer. Arthur pointed out that the aquifer is essential to his livelihood. "The High Plains Aquifer is an open aquifer system containing some 3. ... While agriculture is often pointed to as the reason for a declining water table in the High Plains Aquifer, the fact is that developing irrigation technology continues to make American agriculture the most efficient groundwater user in the world. " According to Arthur's testimony, about 35 percent of Texas' agribusiness is generated in the 41 counties that overlay the aquifer from Lubbock to Amarillo. ... Approximately 30 percent of the income in the Panhandle is dependent on its regional agriculture industry, which is true of all the states that overlie the High Plains Aquifer. ...
