What CORE Environmental Services does
CORE Environmental Services is a private, founder-owned environmental consulting firm established in 2001 by Stephen Zbur and headquartered in Wexford, Pennsylvania, with a second office in Allison Park, PA. The firm provides four interconnected service lines to industrial, commercial, and public-sector clients: Site Characterization and Remediation (UST/AST closure, soil and groundwater characterization, remedial action plans, in-situ remediation, emergency spill response); Compliance Management Services (facility inspections, environmental audits, hazardous waste management, air and discharge permitting, SPCC and stormwater plans); Environmental Due Diligence (Phase I and II Environmental Site Assessments, transaction screens, asbestos and vapor intrusion investigations); and Industrial Hygiene Services (asbestos, mold, lead paint, VOCs, bacterial assessments, and indoor air quality testing). Its customer base spans commercial property owners and developers, industrial facilities, energy companies, environmental service firms, public entities, and individual homeowners and property managers in the Pittsburgh and tri-state (PA, OH, WV) region, with licensed practice extending into New York, North Carolina, South Carolina, and Virginia.
The firm operates a project-based B2B professional services model with quote-based pricing, direct sales, and website-driven inquiries, supplemented by a content-marketing blog covering regulatory updates. Technical capability is anchored in human expertise rather than proprietary software: Professional Geologists (PG), a Licensed Remediation Specialist (LRS), a multi-state Professional Engineer (PE), and a network of affiliated wetlands, ecological, surveying, and computer modeling specialists extend the firm's reach. In-situ soil/groundwater remediation, computer groundwater modeling, and Pennsylvania Act 2 / West Virginia Voluntary Remediation Program expertise are core technical differentiators. Go-to-market relies on direct sales relationships, referrals, the corporate website contact form, and LinkedIn/Facebook presence. The company has no outside funding, no acquisitions, and no documented ownership changes; it is bootstrapped and organically grown, with a team of 11–50 employees across the two Pennsylvania offices.
Revenue is generated entirely through customized consulting engagements billed on a project basis with no disclosed financials, no publicly available pricing, and no software or subscription components. Recent operational signals include steady Staff Scientist hiring from 2022 through 2024, the addition of Industrial Hygiene as a distinct service line targeting new customer segments, and ongoing multi-state licensing and geographic expansion beyond the original Pittsburgh footprint.
