F/S Plus EPA Region 5, F/S Plus is a stand-alone application developed in conjunction with the SADA software developers. F/S Plus can display point data, gridded data (interpolated values), and DXFs. Some of the visualization functions include: zoom, rotation, transparency, point size manipulation, scaling, and slicing. In addition, it has a 2D/3D IDW and kriging interpolation modules that create gridded values that can be displayed with or without the original point data.

FIELDS Rapid Assessment Tools EPA Region 5, Rapid Assessment Tools, or R.A.T., is a standalone windows application that combines global positioning information from a GPS device with single point or continuous field sample data. R.A.T. stores the sample data with its GPS location in a flat file and plots these results in a dynamic, two-dimensional display in real-time. In the software, data can be viewed with aerial photography, polygon boundaries, and sample designs to allow for immediate data availability, analysis, and use in the field. The collected data can also be exported using standard U.S. EPA data formats such as SCRIBE and ESRI Shapefile.

FIELDS Tools for ArcGIS© EPA Region 5, The FIELDS Team has developed a set of tools that integrate the power of geographic information systems (GIS), imaging software, global positioning system (GPS), and in-field sampling and analysis technology. The FIELDS tools are a collection of ArcView extensions and a stand-alone 2D/3D software (F/S Plus) that utilize published methodology for each step in the characterization process. The FIELDS software forms the foundation for a system that provides data analysis and interpretation for environmental decision-making. The results allow project managers to evaluate the extent of contamination and hot spot sizes, estimate health risks, prioritize site goals, and weigh potential actions. Users include U.S. EPA Regions, NOAA's coastal restoration scientists, State and Tribal agencies, as well as the private and academic community.

Spatial Analysis and Decision Assistance (SADA) University of Tennessee, Spatial Analysis and Decision Assistance (SADA) is a free software package from the University of Tennessee that integrates modules for visualizing contaminant concentrations, geospatial analysis, statistical analysis, human health risk assessment, cost/benefit analysis, sampling design, and decision analysis. SADA can be used to address site-specific concerns when characterizing a contaminated site, assessing risk, determining the location of future samples, and when designing remedial action.

A Guideline for Dynamic Workplans and Field Analytics: The Keys to Cost-Effective Site Characterization and Cleanup, sponsored by President Clinton's Environmental Technology Initiative, through the United States Environmental Protection Agency, Washington, DC. Robbat, A.; Tufts University and USEPA, The document was prepared by the Tufts Center for Field Analytical Studies and Technologies to help federal and state regulators, site owners and their consulting engineers, and remediation companies understand what is involved in constructing and carrying out a dynamic workplan using field analytical instrumentation in an adaptive sampling and analysis program for expediting the site investigation process.

Current Perspectives in Site Remediation and Monitoring: Applying the Concept of Effective Data to Environmental Analyses for Contaminated Sites USEPA EPA/542-R-01-013, This issue paper provides detail in support of the article "Managing uncertainty in environmental decisions" that was published in the October 1, 2001 issue of Environmental Science & Technology. It addresses topics related to data quality and how field analytical methods may significantly improve the quality of environmental data by permitting better management of sampling uncertainties.
