Environmental remediation and engineering for contaminated sites and federal facilities

Environmental Services Reston, VA 501–1,000 employees Founded 1987 Privately Held

HydroGeoLogic is an environmental engineering and remediation firm founded in 1987, operating across 500+ employees with deep specialization in contaminated-site cleanup, radiological remediation, and unexploded ordnance clearance. The hiring pattern—heavily weighted toward engineering and operations roles, with senior-level hiring dominating—reflects active project delivery rather than growth-stage recruitment. Tech stack is traditional (CAD, GIS, Microsoft Office, Adaptive Planning) with no visible cloud or automation adoption, suggesting operational maturity in field-driven execution but potential opportunity in proposal and project-management modernization.
