Groundwater Sensitivity Toolkit
API and the California MTBE Research Partnership have produced a software utility to help site managers, water purveyors, and regulators evaluate the sensitivity of a groundwater resource to a potential release of compounds of concern (e.g., an MTBE-oxygenated fuel) at a particular site.
Amigo Software for Evaluating the Potential for Groundwater Impairment
API-AMIGO (v. 1.0 Beta, available as a public beta release.) simulates the chloride concentration in a water table (unconfined) aquifer after an accidental surface release of chloride (e.g. produced water or brine) or after the placement of chloride-rich material at the ground surface, such as in a landfarm or biopile. AMIGO uses the output from library of HYDRUS-1D simulations in a simple ground water mixing model to generate a graph of chloride concentration over time in an imaginary monitoring well located at the edge of the spill, lease or landfarm.
ITRC Environmental Molecular Diagnostics (EMD) (ITRC EMD-2)
The Environmental Molecular Diagnostics (EMD) web-based guidance describes a group of advanced and emerging techniques used to analyze biological and chemical characteristics of environmental samples. EMDs have applications in each phase of environmental site management and provide additional lines of evidence for making better decisions. The guidance provides descriptions of each of the major EMDs, along with case studies of their uses and recommendations regarding the appropriate uses of these techniques. The EMD web-based guidance will help you to understand how EMDs might benefit your site management decisions. View or download at www.itrcweb.org/EMD-2.
GroundWater Spatiotemporal Data Analysis Tool (GWSDAT)
The GroundWater Spatiotemporal Data Analysis Tool (GWSDAT) has been developed by Shell Global Solutions to facilitate spatiotemporal analysis of groundwater monitoring data. It is designed to work with simple time-series data for solute concentration and ground water elevation, but can also plot non-aqueous phase liquid (NAPL) thickness if required. Spatial data is input in the form of well coordinates, and wells can be grouped to separate data from different aquifer units. The software also allows the import of a site basemap in GIS shapefile format. Concentration trend and 2D contour plots generated using GWSDAT can be exported directly to Microsoft PowerPoint and Word to expedite reporting.
The application is supported for Windows XP, Vista and Windows 7 and the corresponding version of Microsoft Office (including 64-bit operating systems). Data input to GWSDAT is via a standardized Excel spreadsheet and the data analysis and plot functions are accessed through an Excel Add-in application. The statistical engine used to perform geo-statistical modelling and display graphical output is the open- source statistical programming language R (www.r-project.org). A user manual and two example datasets are provided with the software for training and demonstration purposes.
