Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Tertiary aquifers are those that occur in older Tertiary age sedimentary deposits (between 66 and 2.6 million years old). Geological reports, maps, and borelogs have been used to identify discreet aquifer units within the Tertiary age geological formations that exist in Southland. These formations consist of a combination of terrestrial, intertidal and marine deposits such as lignite measures and limestone. These are commonly overlain by younger Quaternary age alluvial deposits. Eight hydrogeologic zones have been identified. For more information about these aquifer zones please contact Environment Southland.</SPAN></P></DIV></DIV></DIV>
Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Groundwater zones effectively encompass separate groundwater systems and are utilised as a framework for monitoring, investigation and management of groundwater resources in the Southland region. These groundwater zones are classified into four basic aquifer types which aggregate spatially separate aquifer systems on the basis of similarities in hydrogeology, geomorphology, groundwater - surface water interaction and observed variations in groundwater quality and levels. Individual zones are delineated on the basis of surface water catchments, known geological unit and aquifer extents, hydrogeological properties and resource development.</SPAN></P></DIV></DIV></DIV>
