Description  Back to Top

WHPA is a semi-analytical ground-water flow simulation program used for delineating capture zones in a wellhead protection areaCThe program consists of four computational modules (RESSQC, MWCAP, GPTRAC, MONTEC). WHPA is applicable to homogeneous aquifers exhibiting two-dimensional, steady ground-water flow in an areal plane and appropriate for evaluating multiple aquifer types (i.e., confined, leaky-confined, and unconfined). The model is capable of simulating barrier or stream boundary conditions that exist over the entire depth of the aquifer. WHPA can account for multiple pumping and injection wells and can quantitatively assesses the effects of uncertain input parameters on a delineated capture zone(s). Also, the program can be used as a postprocessor for two-dimensional numerical models of ground-water flow.

Getting Started:

You will need unzipping (compression) software to uncompress ZIP files. If you need to load unzipping software on your computer, free software is available for download on the internet at the following sites:

Leaving EPA -> http://www.pkunzip.com -  PKUNZIP home page
Leaving EPA -> http://www.info-zip.org/ - InfoZip Wiz

Installing the Program:

Four files are available for download

To download and install WHPA, the following procedures MUST be followed:

  1. View the online User's Manual (WHPA.PDF) file for further installation instructions.
  2. Download the fileS WHPA1.ZIP and WHPA2.ZIP.
  3. After downloading, unzip WHPA1.ZIP from your hard drive to a blank formatted 3.5 high-density diskette labeled "WHPA Disk 1"
  4. Unzip WHPA2.ZIP to a blank formatted 3.5 diskette labeled "WHPA Disk 2".
  5. Put the disk labeled "WHPA Disk 1" into the 3.5" drive.
  6. At the DOS prompt, change drives to your 3.5" drive
  7. Type INSTALL.
  8. Follow the on-screen directions and see the User's Manual.
