Decision Support Software

Dynamic field activities often rely on decision support software because large quantities of data must be analyzed and evaluated in a short period of time. The software allows project members to select sampling points, visualize site data in an up-to-date conceptual site model, and generate reports. They can greatly decrease the time required for data processing and facilitating rapid decision making.

U.S. EPA Fully Integrated Environmental Decision Support (FIELDS)

U.S. EPA Region 5 developed this system which combines geographic information systems (GIS), global positioning systems (GPS), database analysis, and imaging technologies to identify, assess, communicate, and help solve environmental problems.
Spatial Analysis Decision Assistance (SADA)

The University of Tennessee, Knoxville, with support from EPA and DOE, and in collaboration with Oak Ridge National Laboratory, has developed a software program that integrates visualization, geospatial analysis, statistical analysis, human health risk assessment, cost-effective analysis, sampling design, and decision analysis.
U.S. DOE Pacific Northwest National Laboratory Visual Sampling Plan software Exit EPA

VSP provides statistical solutions to sampling design to help users decide where samples should be collected and how many are needed.

  • DEFT: Data Quality Objectives Decision Error Feasibility Trials
    A program that allows users to evaluate the financial feasibility of incorporating selected data quality objective (DQO) constrains into a statistical sampling design before developing a final plan. The user can test the proposed constraints on several simple sampling designs (e.g., simple random sampling, composite sampling, stratified sampling).
