SERES-ARCADIS 8(A) JV, LLC

SERES-ARCADIS 8(A) JV, LLC specializes in environmental remediation and engineering services for defense and federal installations, with deep expertise in per- and polyfluoroalkyl substances (PFAS) investigation, remedial action planning, and contaminated site closure. The firm delivers comprehensive site assessments, remedial investigations, and cleanup support for former defense sites, leveraging technical knowledge in soil and groundwater characterization, regulatory compliance under CERCLA and RCRA, and multimedia environmental modeling. Their work includes off-post well investigations, PFAS fate and transport analysis, and UXO/ munitions response support, demonstrating proficiency in complex regulatory frameworks and interdisciplinary environmental engineering. A key differentiator is their ability to integrate engineering design with remediation execution, ensuring defensible records of decision and seamless transition from investigation to remediation phases. The contractor maintains a consistent relationship with the Department of Defense, delivering environmental compliance and restoration services across active and formerly used defense sites nationwide. Their engagements consistently involve installation-wide cleanup programs, including FUDS sites and joint base remediations, indicating a trusted role in supporting the DoD’s Environmental Restoration Program and Installation Restoration Program objectives. Their primary focus lies in NAICS 541330 (Engineering Services) and 562910 (Remediation Services), positioning them as a technical integrator for defense environmental projects requiring both engineering design and field implementation. They specialize in PFAS contamination response, munitions clearance, and site closure documentation—areas of high demand within military environmental restoration. As an 8(a) joint venture structured as a 2K entity, the firm leverages small business advantages while combining the technical depth of its parent companies. Based in Charleston, SC, it operates nationally with a focused presence in defense environmental markets, serving as a responsive, mission-aligned partner for complex federal remediation challenges.
