What’s New in Version 2.0

The Decision Support Tool (DST) Matrix  has been updated in order to stay current with the evolution of environmental investigation and remediation technology.  The DST Matrix Version 2.0 includes five new DSTs in the matrix, one new mini-case study and updates the information on the 20 DSTs that were included in Version 1.0, including notes about new features, new versions and documentation. The DSTs added were evaluated using the same process and criteria as Version 1.0 (Development of DST Matrix (742K/24pp/PDF)). 

The new DSTs include:

  • Biobalance Toolkit:  The Biobalance Tool Kit provides a suite of analytical models and routines to estimate the mass balance of electron donors and acceptors in a chlorinated solvent plume emanating from a source area. These tools are designed to give site managers an approach to demonstrate whether the assimilative capacity of a system is capable of reducing or eliminating the mass flux of chlorinated solvents emitted from a source zone.
  • Mass Flux Toolkit:  Mass Flux Tool Kit is a Microsoft Excel spreadsheet that gives site personnel the capability to compare different mass flux approaches, calculate mass flux from transect data, and apply the results of mass flux analysis to manage groundwater plumes more quickly and easily.
  • ProUCL:  ProUCL estimates the 95 percent upper confidence limit (UCL) of an unknown population mean of environmental data sets. ProUCL is designed to summarize and graph simple statistical analysis and may be used on a number of different media.
  • Rapid Analysis Tools (R.A.T.):  R.A.T. is a Microsoft Windows based software package that provides field teams real-time field data collection and mapping. The software enables users to collect data from monitoring devices in real-time, integrate device data with descriptive data and user-created polygons, lines, and point sample designs, before exporting data as ESRI shapefiles or SCRIBE or Access databases.
  • WhAEM 2000:  WhAEM2000 is a groundwater flow model designed to facilitate delineating capture zones and mapping well head protection areas (WHPAs).

 

A new case study that discusses the use of the Spatial Analysis and Decision Assistance (SADA) software for a soil removal project is also included.
