Aquifer Test Analysis Software

"This software is great! We plan to buy another seat,
waiting on purchase order. The output is very readable and
options are fast and easy to use."

The First Commercial Aquifer Testing Software for Windows

Windows 7 Compatible Environmental Software Windows 10 Compatible Environmental Software The latest versions of all Starpoint Software applications run on Windows 2000 through Windows 7 64-bit up to Windows 8/10

  • Easy to use Windows interface with context sensitive on-line help
  • Drag-and-drop type curve matching
  • Extensive ability to exclude data with on-screen buttons
  • Importing most manufacturers' data logger files without prior editing
  • Extensive resistance to program crashes from unusual data sets
  • Automatically adjusting slug-test data for maximum displacement at time = 0
  • Displaying calculations in moveable and customizable text boxes
  • Instantaneous type curve display
  • Copy graphs to clipboard or save as a bitmap

Features Common to All Three Programs:

  • Display graphs in any language*
  • Multiple fonts for all graphs
  • Many calculations displayed in customizable, moveable text boxes
  • Consistent user interface between all programs
  • Improved display of results for Automatic Parameter Estimation (with multiple fonts)
  • Export reports to tab-delimited files or rich-text format

  • Drag-and-drop type curve matching
  • Up to 2000 time and drawdown values
  • In addition to the wide variety of pre-defined units, user-defined units for transmissivity, hydraulic conductivity, and discharge rate are now supported.
  • Extensive choice of symbols for both included and excluded data display
  • Customizable graph axes; specify maximum values and tick mark spacing
