Here, we compute the aquifer-scale cumulative distribution function to characterize the age distribution for 21 Principal Aquifers that account for ~80% of public-supply pumping in the United States.The 16 aquifers of the State were divided into two major physiographic regions of the State: the Coastal Plain Province (referred to as Coastal Plain) of eastern and southern Arkansas, which …Sixteen aquifers in Arkansas that currently serve or have served as sources of water supply are described with respect to existing groundwater protection and management programs, geology, hydrologic characteristics, water use, water levels, deductive analysis, projections of hydrologic conditions, and water quality. State and Federal protection and management programs are described according ...

This data set represents the extent of the Mississippi River Valley alluvial aquifer in the states of Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Purpose: Supplemental_Information: The juxtaposition of regionally mapped aquifers has led to some instances where an aquifer outcrop or shallow subcrop is bounded by a State ...Abstract. The Mississippi Embayment aquifer system is composed of six regional aquifers covering about 160,000 square miles in parts of Alabama, Arkansas, Illinois, Kentucky, Louisiana, Mississippi, Missouri, and Tennessee. The flow analysis presented in this report as part of the Gulf Coast Regional Aquifer-System Analysis study pertains to ...This map shows aquifer water level declines across western and central Kansas based on preliminary results from the annual Kansas Geological Survey assessment taken in early 2022. But those accelerating depletion rates didn’t come as a surprise to Brownie Wilson, the survey’s water data manager.Aquifers are underground layers of porous and permeable rock or unconsolidated sediment, such as sand and gravel, that hold water. Porous means that rocks contain pores, or holes, and permeable means the pores are interconnected in a way that allows water to flow from pore to pore. Spaces containing water in sand and gravel or loosely …Aquifers of Arkansas—Protection, Management, and Hydrologic and Geochemical Characteristics of Groundwater. Alma Dyer Van Buren Fort Smith.

At only 15 to 30 gpm, the Springfield Plateau Aquifer produces smaller amounts of water than either the St. Francois or Ozark aquifers. However, the aquifer’s shallow depth makes it a good target for private domestic wells. Separating the Springfield Plateau and Ozark aquifers is Ozark Confining Unit composed of shales and limestones.Abstract. Sixteen aquifers in Arkansas that currently serve or have served as sources of water supply are described with respect to existing groundwater protection and management programs, geology, hydrologic characteristics, water use, water levels, deductive analysis, projections of hydrologic conditions, and water quality. ….

The National Ground-Water Monitoring Network compiles information from over 7,000 groundwater monitoring wells across the country, including Federal, State, and local groundwater monitoring networks. Although the image above only shows the contiguous United States, the interactive map also includes wells from Alaska, Hawaii, Puerto Rico, Guam, and the U.S. Virgin Islands. Users can filter and ... Both aquifers range in thickness from 200 to 800 metres. In addition, the Dammam and Umm er-Radhuma aquifers, which extend into the western desert areas, contain highly saline water. The recharge of shallow aquifers depends mainly on rainfall events and surface run-off, and thus may vary considerably from year to year.

Water is the human vital requirement for life; in these days, decreasing of the fresh water increases the importance of the aquifer water. However, Upper Egypt is higher than north Egypt, so the water map continually changes daily, and the aquifer water is deeper than 10 m. The ground penetrating radar (GPR) system is used for underground …Herein, aquifers in the Sparta Sand and Memphis Sand will be referred to as “the Sparta-Memphis aquifer” throughout Arkansas. During the spring of 2011, 291 water levels were measured in wells completed in the Sparta-Memphis aquifer and used to produce a regional potentiometric-surface map.
