EEC Environmental

What EEC Environmental does

EEC Environmental (legal name: Environmental Engineering and Contracting Inc.) is a US-based private environmental and engineering consulting firm founded in 1995 and headquartered in Orange, California. The firm specializes in site investigation and remediation of soil, soil vapor, and groundwater, alongside wastewater pretreatment, stormwater compliance, PFAS assessment and treatment, environmental due diligence, and litigation/expert witness support. It serves both public sector clients (municipal governments, water and sanitary districts, state and federal agencies) and private sector clients across manufacturing, industrial laundries, dry cleaners, real estate developers, oil and gas, aerospace/defense, and utilities.

The firm's technical capabilities rest on specialized human expertise and field-deployed remediation systems rather than proprietary software. Differentiated offerings include in-situ remediation design (including monitored natural attenuation, in-situ chemical oxidation, and enhanced biological treatment), operation of six Soil Vapor Extraction (SVE) systems in Southern California, industrial pretreatment system design and build up to 2.5 MGD, stormwater compliance programs including Local Implementation Plans and Exceedance Response Actions under California's Industrial General Permit, GIS/CAD-based data management (with partnerships to Esri, Cityworks, and AWS), and climate change modeling/hydrologic risk assessment led by an MIT-trained climate scientist. Staff credentials include a hydrogeologist licensed in 14 states, a former 30-year EPA Clean Water Act compliance veteran, and a Principal Chemist serving as CEO.

EEC generates revenue through project-based professional services fees, delivered via direct consulting engagements and on-call municipal contracts. The go-to-market model is consultative and relationship-driven, supported by conference sponsorships (ABA Environment/Energy/Resources Section, California CUPA, CWEA P3S, NPHA Annual Meeting), thought-leadership content, and membership in industry associations. The firm operates from offices in Southern California, the Mid-Atlantic (Annapolis, MD), and a newly opened Midwest location (2025), with additional international engagement including a Chinese mayoral delegation. No external funding, no parent company, and no disclosed ownership changes appear in available sources.
