ACC Environmental Consultants

What ACC Environmental Consultants does

ACC Environmental Consultants, Inc. is a 100% employee-owned, multi-practice environmental consulting firm founded in 1986 and headquartered in Oakland, California. The firm provides professional environmental services — Phase I and Phase II Environmental Site Assessments under ASTM E1527-13/21 and EPA AAI standards; asbestos, lead-based paint, mold, and silica testing and consulting; indoor air quality and industrial hygiene services; soil, groundwater, and storage tank investigations; hazardous materials management and CUPA compliance; LEED green building support; emergency response; and expert witness services. It also delivers certified training courses in person at Oakland and Los Angeles venues and virtually. Customers span four primary verticals: schools and colleges, lenders and brokers, property owners and managers, and government agencies.

The company's underlying technology stack combines industry-standard field methodologies (ASTM, EPA, OSHA, state-specific environmental regulations) with a proprietary software asset, the ADAM Environmental Information Management System, developed and sold by its wholly-owned subsidiary EcoLogic Systems to environmental consulting firms, Fortune 500 companies, school districts, and public agencies worldwide. ACC does not offer a SaaS platform for its own services; all consulting work is delivered as project-based professional engagements by credentialed staff (Professional Geologists, Board-Certified Industrial Hygienists, Certified Asbestos Consultants, CDPH Lead professionals, Certified Hazardous Materials Managers).

The business model is professional services revenue: quote-based fees for environmental consulting projects plus training-course tuition. Distribution is direct-to-client via a Request-a-Proposal funnel, field service delivery, and training enrollment. The company has expanded through two acquisitions — HydroCon Environmental (January 2023, Pacific Northwest) and Sensible Environmental Solutions (March 2026, Northern California) — taking the combined entity to 45+ employees across six states with offices in Oakland, Los Angeles, Seattle, Vancouver WA, Longview WA, and Bend OR, and coverage into Alaska, Hawaii, and Arizona.
