  1. Classification of Aquifers Systems in U.S. • Fuller, 1905 • Meinzer, 1923 • Thomas, 1952 • RASA, 1978 • Heath, 1984 • Heath, 1988 • Hydrogeologic Atlas, 1990s

  2. 21 regions, based on bedrock aquifers Aquifer Regions in U.S. according to Meizner, 1923

  3. Combined and simplified to 10 regions Aquifer Regions in U.S. according to Thomas, 1952

  4. 28 regions, extensive aquifers that act as single unit, independent aquifers with common characteristics

  5. Summary of U.S. Water Resources, Classification based on watersheds USGS Professional Paper 813

  6. Ground Water Regions (Heath, 1984) 1. Component aquifers—unconfined, confined, multiple 2. Porosity—primary, secondary 3. Aquifer composition 4. Storage and Transmission characteristics

  7. Regions based on rock type, Heath

  8. Hydrogeologic Characteristics of Aquifer Regions, Heath, 1984

  9. Aquifer Regions in U.S. according to Heath, 1984

  10. Alluvial Aquifer Systems, according to Heath (1984)

  11. Aquifer regions in North America. From Heath (1988) in Hydrogeology, Back and others

  12. Which classification is right?
