HGL-ER JV LLC

HGL-ER JV LLC specializes in environmental remediation services for complex contaminated sites, with a demonstrated focus on Superfund site cleanup under the Department of Defense. Their core capabilities include hazardous substance removal, soil and groundwater remediation, and long-term stewardship activities at legacy industrial and military locations. The contractor applies engineered solutions such as in-situ bioremediation, excavation and off-site disposal, and institutional controls to meet CERCLA and RCRA regulatory standards. Technical expertise spans site characterization, risk assessment, remedial design, and compliance with EPA and DoD environmental directives. Their specialization in Superfund site execution—evidenced by direct work at the Ely Mine site in Vermont—positions them as a contractor adept at navigating stringent federal environmental mandates, coordinating with multiple regulatory stakeholders, and delivering technically rigorous, defensible cleanup outcomes. The contractor’s primary agency relationship is with the Department of Defense, where they deliver environmental restoration services at former defense facilities and contaminated land parcels. Their work supports DoD’s Installation Restoration Program and Defense Environmental Restoration Program, focusing on remediation of munitions residues, heavy metals, and industrial contaminants left from historical operations. This consistent engagement suggests a trusted partnership built on reliability in high-regulatory environments and adherence to military environmental compliance frameworks. HGL-ER JV LLC operates primarily within NAICS 562910, which encompasses hazardous waste remediation and environmental cleanup services. Their market positioning centers on federal environmental remediation, particularly at sites with complex contamination profiles requiring multidisciplinary technical approaches. They serve the defense and federal environmental restoration market with a narrow but deep focus on Superfund and military site cleanup. As a 2L joint venture based in Reston, Virginia, the company leverages regional proximity to federal regulators and defense infrastructure. While no government certifications are currently listed, their operational footprint reflects a strategic alignment with federal environmental compliance requirements and mission-critical cleanup missions.
