Mann-Kendall - Toolkit Software Brochure

The GSI Mann-Kendall Toolkit is a free, simple, easy-to-use software tool to help environmental professionals efficiently conduct concentration trend analyses for any groundwater constituent.  Programmed in the Microsoft Excel spreadsheet environment, the software employs the same Mann-Kendall plume stability methodology that was previously developed for the MAROS software (Aziz et al., 2003; AFCEE, 2004).  This software tool can be used to demonstrate the plume stability condition (expanding, stable, or decreasing) and track the progress of remediation efforts, in a quantitative and consistent manner for consideration by both site managers and regulatory personnel.
