NOVEMBER 3, 2009 — HGL is pleased to announce the development of the next generation Munitions and Explosives of Concern (MEC) Identification Tool: MEC-ID. This tool provides a realistic approach to MEC removal cost savings - given site risk and uncertainty - leading to optimized range response and clearance decisions. The tool provides a completely open, transparent, and stakeholder-reviewable analysis, and uses error-guarded analysis to increase the discrimination's safety and certainty. Discrimination results are not hidden, because neither black boxes nor feature-lumping techniques are used. MEC-ID uses credible features developed by geophysicists for building discrimination models: it enhances QA/QC of geophysical data collection, readily handles thousands of candidate features, and then automatically down-selects them and focuses on the high priority items for MEC classification at a specific site. MEC-ID handles multiple MEC types simultaneously and can operate in either static (fixed data set training) or online (real-time) mode for production clearances. MEC-ID is robust and explicitly computes the probability of various potential MEC types and clutter. The tool uses data obtained from any MEC sensor currently in field-use today. MEC-ID has been peer reviewed and was recently validated using production quality geophysical data from a complex MEC site in South Dakota⁽¹⁾.

The first FTMO module planned for release is the groundwater pump and treat optimization tool (flow and transport). It will be integrated with HGL's MODFLOW-SURFACT groundwater flow and transport code. FTMO is a comprehensive optimization tool-kit that has evolved from research first conducted at the Massachusetts Institute of Technology in the 1980s. FTMO has been applied to a wide spectrum of challenges, including prioritization of programmatic portfolios at the Department of Energy (DOE), Superfund reauthorization legislation (HR2500), health and safety issues at the DOE, remedial designs and ordnance discrimination, monitoring well placement, and even power plant design and future megawatt output predictions. FTMO is based on powerful and effective optimization technology, which has proven itself in numerous applications. The greatest independently verified cost savings to date, $20M, is from its application to a DOE environmental health and safety challenge. The application of the FTMO technology has also received numerous accolades, the highest of which is the U.S. Vice Presidential Hammer Award. HGL's goal is to promote the use of this toolkit by creating user-friendly applications. The first of the modules to be released is for groundwater management optimization, including groundwater cleanup optimization. By using FTMO in combination with MODFLOW-SURFACT®, modelers will be able to tackle problems such as: 1. Designing optimal groundwater remedial systems, including where multiple plumes exist and accounting for cost, time and other site- and project-specific constraints; 2. Optimizing design and operation of potable supply well fields; and 3. Optimizing regional aquifer resource management planning.
