HGL is a full-service munitions response provider with the capabilities to effectively execute any project, regardless of size or location, from concept through completion. HGL accomplishes this by developing tailored technical approaches specific to the unique characteristics associated with each site. These technical approaches are then safely implemented using well-qualified personnel following HGL’s mature, time-proven corporate procedures and regimented approach to munitions services.
Whether we’re developing innovative solutions, expediting removal activities, or negotiating restoration exit strategies; HGL’s multidisciplinary project delivery teams of program managers, project managers, UXO specialists, geophysicists, engineers, information and geospatial technologists, numerical modelers, and environmental scientists focus on integrating their specialized skills and experience to meet client expectations, minimize performance risk, and efficiently optimize limited resources to meet project objectives.
The primary goal of characterizing a site under the MMRP is to collect and analyze the data necessary to determine the nature and extent of MEC and MC contamination present at a site and to perform the associated risk assessments necessary to quantify risks and explosives safety concerns to human health and the environment. HGL accomplishes these goals by tailoring its characterization designs to each Munitions Response Site (MRS). This characterization design is prepared for both MEC and MC using statistically based methodologies and tools such as Visual Sample Plan (VSP) and UXO Estimator software. This statistical-based approach ensures that the right type, quality, and quantity of data are gathered to support confident decisions as to the nature and extent of contamination and the associated risk. Once this characterization design is established, it is implemented using a mature toolbox of techniques and activities as follows:
- Reconnaissance- HGL employs the use of both visual and instrument- aided reconnaissance where appropriate to quickly gain insight into areas of greatest concern based upon data collected over both linear and meandering path transects. This tool allows HGL to quickly and cost effectively optimize other aspects of its characterization efforts.
- Digital Geophysical Mapping- HGL provides comprehensive, nonintrusive geophysical services to the environmental, engineering, geological, and construction industries. Whether the scope of work is identifying buried munitions, mapping underground utilities, or determining geologic structures, HGL’s approach is to deploy the right tools for the specific site conditions that will enable HGL to provide the project-critical results in an accurate and easy to access geo-referenced format. HGL’s geophysicists have the experience necessary to identify MEC items in the subsurface and understand the value of providing near “real-time” results to our clients. HGL’s advanced use of proprietary algorithms for data analysis and processing enhances target picking and effectively maximizes its clients’ return on investment.
- Intrusive Investigations- HGL’s team of seasoned UXO professionals has the experience and capabilities to quickly perform intrusive investigations in support of site characterization activities. HGL’s personnel can quickly and efficiently reacquire identified anomalies for intrusive investigation, and can then safely excavate them, identify MPPEH and classify it, and efficiently dispose of the items through demolition and/or solid waste disposal.
- MC Sampling – HGL has experience conducting MC and HTRW sampling activities and subsequent fate and transport modeling. HGL balances its MC sampling approach using an observational approach in that it focuses sampling efforts on those areas with the highest probability of containing MC contamination as evidenced by the presence of MEC and MD in the area. This approach allows HGL to minimize the overall number of samples that must be obtained, analyzed, validated, and evaluated to ensure that a representative sample population to support risk assessment efforts has been obtained.
MEC Removal and Disposal
The primary goal of conducting a MEC removal is to eliminate the risk associated with ferrous or nonferrous items present within a given area. HGL tailors the removal approach specific to the potential risk associated with the munitions present, the site conditions, and the current and future land use. This approach can include a surface clearance, a subsurface clearance, or a combination of both.
HGL applies an adaptive approach to MEC removal using a full suite of methods applied to specifically address the budgetary, schedule, and physical limitations present on each project. This toolbox includes use of methods such as analog geophysical detection and removal; digital geophysical mapping, detection, and removal; robotic assisted removal; use of up-armored equipment for removal; manual sifting of removed soils; and mechanical sifting of removed soils. HGL deploys what is needed for the project when it is needed in order to most efficiently achieve the required end state of clearance completed.
Range Maintenance and Construction Support
HGL provides range maintenance and construction support services to maintain active military firing and bombing ranges, including the periodic removal of MEC and MD near an impact zone and providing support for the maintenance and replacement of range targets. HGL’s approach to providing these services is derived from its focus on the customer and emphasis on effective communications with the contractual client, the installation, and range control. This range maintenance can include dedicated MEC removal as discussed previously or it can include MEC/UXO avoidance measures in support of construction.
HGL has been performing MEC/UXO avoidance support for both horizontal and vertical construction, cultural and archaeological investigations, and underground environmental investigation activities for both federal and commercial clients. HGL works closely with its clients to develop an approach to MEC/UXO avoidance that ensures the safe conduct of the project factoring in the relative risk of exposure and the specifics of the activity being performed.
