CORNERSTONE GC, LLC specializes in environmental services and waste management solutions aligned with federal compliance and sustainability standards. Leveraging deep expertise in hazardous and non-hazardous waste handling, remediation support, and regulatory adherence under RCRA and CERCLA frameworks, the company delivers integrated environmental management services tailored to government infrastructure and facility operations. Their technical capabilities include spill response planning, decontamination protocols, waste stream characterization, and environmental sampling and monitoring, with a focus on minimizing ecological impact while ensuring full compliance with EPA and DoD environmental regulations. A key differentiator is their commitment to sustainable disposal practices and closed-loop resource recovery systems, enabling clients to meet stringent federal green procurement goals. Award history is not available to confirm specific agency engagements, but the contractor’s NAICS classification and certifications suggest alignment with environmental cleanup, facility support, and infrastructure maintenance contracts typically awarded by agencies such as the Department of Defense, General Services Administration, and Environmental Protection Agency. Their operational model is designed to support mission-critical environmental compliance across military bases, federal laboratories, and public works sites. The primary NAICS code 562910 — Other Remediation Services — reflects a focus on site assessment, soil and groundwater remediation, and contaminated media management. This positions CORNERSTONE GC as a niche provider in the federal environmental services market, particularly suited for projects requiring specialized handling of regulated substances and regulatory documentation under federal environmental statutes. As a Women-Owned Small Business and Woman-Owned Business certified contractor, CORNERSTONE GC operates from Floresville, Texas, with a lean, agile structure optimized for responsive service delivery. Their certifications enhance eligibility for set-aside contracts and demonstrate alignment with federal diversity and inclusion initiatives, reinforcing their role as a trusted small business partner in the government environmental services sector.
