HYPERVENTILATE is an interactive software guidance system for evaluating the feasibility of using Soil Vapor Extraction (SVE) at a specific site based on site and contaminant characteristics. HYPERVENTILATE is designed to (1) identify the level of site data required to evaluate the SVE system, (2) evaluate soil permeability test results, (3) approximate the minimum number of extraction wells likely to be needed, and (4) provide a rough approximation of the system's desired and maximum removal rates. HYPERVENTILATE contains a guidance system based upon recent SVE research and analytical methods based upon research and empirical data to evaluate soil permeability test results and perform a screening level design of an SVE system. Sensitivity analyses of HYPERVENTILATE results can easily be performed using the program to assess uncertainties in site and contaminant characteristics.

HYPERVENTILATE operates under MS Windows, is menu-driven, provides for interactive data entry and editing, and includes the Spinnaker Plus system to review graphical guidance information. The program produces output in tabular and graphical format. Although the HYPERVENTILATE computational module is in the public domain, IGWMC's version is considered proprietary because of inclusion of the licensed Spinaker graphics software. The distributed disks contain executable image, guidance data sets, examples data sets and a single-use runtime version of the Spinnaker Plus V. 2.5 program. The documentation includes installation instructions and a user's manual.
