Military Munitions Response

ERT supports military munitions investigation and remediation nationwide with a focus on determining the most appropriate approach to mitigating munitions and explosives of concern (MEC) and munitions constituents (MC) hazards to the public, balancing factors such as cost and public acceptance.

Our staff of highly experienced UXO Program and Project Managers, industry expert geophysicists, and military-trained and certified unexploded ordnance (UXO) technicians have supported MMRP investigations, the management of material potentially posing explosive hazard (MPPEH) including explosive demilitarization, time-critical/emergency actions, and support for construction projects located in sites with potential for the presence of MEC. ERT also provides advisory services to identify the most cost-effective MEC response actions required to address MEC issues, and community/regulatory coordination for evacuations and approvals.

ERT geophysical capabilities include man-portable terrestrial, towed-array, and marine digital geophysical mapping using state-of-the-art geophysical and navigational equipment and data processing systems. ERT has developed site-specific MEC target identification and characterization methods to successfully reduce false-positive intrusive investigations and project costs on MEC removal activities. Our senior military munitions program staff have DoD explosives safety policy development experience, and have written and reviewed explosive safety planning documents for a wide range of conventional and chemical munitions sites.

Case Studies

Lake Erie Off-Range Cleanup Site, OH: Under a fixed-price performance-based contract task order award, ERT is performing both terrestrial and aquatic RI/FS, engineering evaluation/cost analysis (EE/CA), and MEC removal actions along approximately eight miles of the Lake Erie shoreline, encompassing more than 100 acres of land and 350 acres of water. The work is adjacent to and related to historic range activities at the Camp Perry National Guard training facility. ERT oversees and facilitates involvement with representatives from USACE Baltimore and Louisville Districts, Army National Guard, Ohio EPA, and public representatives. Additional stakeholders include more than 250 private residences, the Davis-Besse Nuclear Power Plant, the Toussaint River Rod & Gun Club, and ARES, Inc. Ohio EPA is a driving force on this project due to very high levels of public concern, and ERT has received numerous compliments from the state on our performance. Through TPP, ERT proposed a VSP-generated statistical approach to RI DGM investigations including transects, cluster analysis and follow-up grids. ERT has completed surface removal of MEC items and demilitarized MPPEH on the beach prior to disposal. ERT self-performed DGM using a four-sensor EM61-MK2A towed array in an amphibious arrangement, towed by a tracked ‘Marsh Master’ vehicle on land and in water. Targets were selected using Geosoft UXDetect™ and a site-specific background noise based target threshold. The results were analyzed with VSP to locate anomaly clusters and recommend grids for full-coverage DGM survey. UXO Intrusive target investigations will be used to perform MEC Hazard Assessment and determine the need for potential further actions.

Spring Valley, Washington, DC: Since 2007, ERT has been serving as the prime contractor on four task orders performing public outreach and education for ongoing investigations; digital geophysical mapping (DGM) in support of CWM/MEC removal actions; and a site-wide RI/FS at this high-profile FUDS in northwest Washington, D.C. The project includes extensive monthly interactions with an active RAB and project stakeholders including American University, foreign embassies, U.S. EPA Region 3, Washington, D.C., Department of the Environment, and two USACE districts.
