-- Name --<br /></p><p>Aquifer<br /></p><p>-- Definition --<br /></p><p>A wet underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, silt, or clay) from which groundwater can be usefully extracted using a water well.<br /></p><p>-- Description --<br /></p><p>An underground geological formation able to store and yield water.<br /></p>
Attribute
Public AquiferTypeValue
  aquiferType

Details:

Notes: -- Name --<br /></p><p>Type of Aquifer<br /></p><p>-- Definition --<br /></p><p>The type of aquifer.<br /></p><p><br /></p><p>-- Description --<br /></p><p>Water in an Aquifer is, or is not, under pressure. Based on that unconfined, confined, artesian, or subartesian types are distinguished. <br /></p>
Public HydroGeochemicalRockTypeValue
  hydroGeochemicalRockType

Details:
obligation=implementingRule
Notes: -- Name --<br /></p><p>Hydrogeochemical Type of Rock<br /></p><p>-- Definition --<br /></p><p>The rock type with respect to the soluble rock components and their hydrogeochemical influence of groundwater.<br /></p><p><br /></p><p>-- Description --<br /></p><p>Defines the prevailing geochemical character of natural groundwater within the Aquifer. <br /></p>
Public Boolean
  isExploited

Details:
Notes: -- Name --<br /></p><p>Is Exploited<br /></p><p>-- Definition --<br /></p><p>Indicates if groundwater from aquifer is exploited by wells or intakes<br /></p>
Public Boolean
  isMainInSystem

Details:
Notes: -- Name --<br /></p><p>Is Main In System<br /></p><p>-- Definition --<br /></p><p>Indicates if aquifer is the main useful aquifer in the aquifer system <br /></p>
Public AquiferMediaTypeValue
  mediaType

Details:
obligation=implementingRule
Notes: -- Name --<br /></p><p>Type of Media<br /></p><p>-- Definition --<br /></p><p>The classification of the medium in which the groundwater flow occurs.<br /></p>
Public QuantityValue
  permeabilityCoefficient

Details:
Notes: -- Name --<br /></p><p>Permeability Coefficient<br /></p><p>-- Definition --<br /></p><p>The volume of an incompressible fluid that will flow in unit time through a unit cube of a porous substance across which a unit pressure difference is maintained.<br /></p><p><br /></p><p>-- Description --<br /></p><p>The parameter represents the hydraulic conductivity of a rock container. Describes the ease with which water can move through pore spaces or fractures. It depends on the intrinsic permeability of the material and on the degree of saturation.<br /></p><p>NOTE: Because of their high porosity and permeability, sand and gravel have higher hydraulic conductivity than clay or unfractured granite aquifers.<br /></p>
Public QuantityValue
  storativityCoefficient

Details:
Notes: -- Name --<br /></p><p>Storativity Coefficient<br /></p><p>-- Definition --<br /></p><p>The ability of an aquifer to store water.<br /></p>
Public QuantityValue
  vulnerabilityToPollution

Details:
Notes: -- Name --<br /></p><p>Vulnerability To Pollution<br /></p><p>-- Definition --<br /></p><p>An index value or interval of values determining the potential degree of aquifer risk arising from the geological structure, hydrogeological conditions and the existence of real or potential source of contamination.<br /></p><p><br /></p><p>-- Description --<br /></p><p>A single value should be used if it is determined directly from the DRASTIC method. If attribute data comes from another data source which is expressed by categorized items, for example: low, moderate or high, interval should be used expressed by lowest and highest value of category. EXAMPLE: ‘Moderate’ means interval from 101 to 140. <br /></p>
