EA assists our clients by minimizing the explosive hazard and future liabilities from munitions and explosives of concern (MEC), including unexploded ordnance (UXO) and discarded military munitions, and by the assessment and remediation of human health and ecological risks due to munitions constituents (MC).

Our Munitions Response Services platform includes the following:

20 Years of Excellence

EA knows what it takes to effectively assess and respond to risks posed by UXO, discarded military munitions, and MC.  Our 20-year partnership with Department of Defense (DoD) testifies to our ability to successfully address the safety, human health, and environmental challenges associated with MEC.  With our well-established Munitions Response Services platform, EA continues to support DoD’s mission to minimize future liabilities, while enhancing long-term sustainability.

Addressing Public and Regulatory Concerns

EA has a proven track record of effectively working with stakeholders and gaining their concurrence on critical issues such as future land use controls and remedial actions.  As evidenced by our success supporting the DoD’s Operational Range Assessments, Military Munitions Response Program, and Formally Used Defense Sites program, EA has developed strong working relationships with DoD personnel, and state and federal regulators nationwide, including territories outside of the continental United States.  EA’s success in gaining stakeholder consensus is facilitated by our understanding and implementation of Uniform Federal Policy (UFP) for Quality Assurance Project Plans (QAPPs), including the Munitions Response QAPP Module 1.  EA utilizes this consistent, streamlined, systematic planning process on every MEC project, which results in reduced review times and revision cycles—providing significant cost savings.

Safety is EA’s No. 1 Priority

EA has never had an Explosive Safety Incident or Accident.  Every person working on an Munitions Response Site (MRS) project has the authority and responsibility to “stop work” in the face of unsafe work conditions, and this empowerment directly contributes to EA’s outstanding safety record.  Through a concerted company effort led by our Corporate Health and Safety Director, EA perpetuates a “culture of safety” throughout the entire organization.  EA’s commitment to safety is constantly communicated through safety newsletters, monthly company-wide safety conference calls, risk management reviews, and open communications with our clients.  Practicing both their responsibility and accountability for maintaining EA’s exemplary safety performance, our in-house UXO-qualified personnel (including Senior UXO Supervisors, Quality Control Supervisors, and Safety Officers) actively participate in every risk and technical document review to ensure project safety and compliance with all DoD, state, federal, and EA corporate policies.

Munitions Response

EA provides expertise in munitions and chemical data management, geographic information system (GIS) mapping and analysis, and field data collection methods utilizing electronic tablets, drones, and hi-accuracy Global Positioning System (GPS) units.  Using Esri’s ArcGIS software platform, EA integrates field data collected via tablet applications and Trimble GPS technology directly with mapping outputs and database deliverables by linking GIS with Earthsoft’s Equis database to comply with Department of Defense (DoD) data deliverables.  EA has provided both spatial analyses and interactive mapping capabilities on over 100 munitions response and operational range assessment projects, allowing our field personnel to capture and process data for same-day results that can be made available to the client.  With the addition of drone technology, EA has expanded its services to provide real-time aerial coverage of project sites and topographical assessments.

EA is recognized in the munitions industry as experts in designing and performing digital geophysical mapping (DGM) surveys for the purpose of identifying subsurface MEC hazards.  We utilize the most current DGM equipment and software in a variety of difficult environments that include forests, steep terrain, residential, and underwater (oceans, back-bays, rivers, and marshes).

EA, as the prime contractor, manages all aspects of munitions response removal actions with the support of our in-house team of munitions response technical personnel and UXO-qualified technicians.  EA produces all planning documents, explosive safety documents, and reports and provides corporate quality control and safety oversight.  We are licensed by the Bureau of Alcohol, Tobacco, and Firearms to purchase explosives, and maintains personnel with State Blasters licenses.

EA has a thorough understanding of the CERCLA process to achieve a comprehensive remedial investigation/feasibility study.  This is accomplished by development of UFP-QAPPs including the Munitions Response QAPP Module 1, that crosswalk the CERCLA program and meet the remedial action objectives.  As a full-service provider, our staff combines the professional environmental disciplines and UXO expertise into one cohesive investigative team.

Since 2005, EA has supported the DoD’s Operational Range Assessments (ORAs). ORAs are part of an initiative to support long-term range sustainability while protecting human health and the environment. In accordance with DoD Directive 4715.11 and DoD Instruction 4715.14, the ORA process evaluates the potential for the MC migration from operational range areas to surrounding off-range areas, and for this migration to cause potential unacceptable human health or ecological risks.

Since program inception, EA has conducted over 680 ORAs at 426 Army and Air Force (National Guard, Active, and Reserve) installations across all continental United States.  EA’s work also spans installations outside the continental United States in Alaska, Hawaii, American Samoa, Turkey, Italy, Germany, and England.

For over 20 years, EA has provided UXO Construction Support Services to the construction industry at sites potentially impacted with munitions.  With a nationwide database of UXO Technicians, EA can mobilize to a site within 48 hours or less to support on-call project needs and unexpected UXO finds.  We have successfully provided UXO Construction Support Services at numerous sites, including Aberdeen Proving Grounds, Maryland; Marine Corps Base at Quantico, Virginia; Fort Meade, Maryland; and Camp Lejeune, North Carolina.

Our UXO Construction Support Services are performed in both terrestrial and marine environments for a wide range of construction project activities such as planning and site survey, site preparation and layout, excavation and material management, wetland delineation, soil borings for pole/well installation, and utility installation and relocation.  EA’s UXO Technicians identify and clear areas of UXO prior to and during construction activities to ensure worker safety in potentially impacted areas.  In addition, our services include preparing Work Plans, Safety and Health Plans, providing MEC/UXO Awareness Training and Daily Safety Briefs, and preparation of Daily Reports, including global positional data for UXO finds and the boundaries of areas cleared.
