Integrated Support from Assessment Through Cleanup & Closure

Encon Environmental supports sites throughout California—from initial due diligence through investigation, remediation, and regulatory closure. Our work is grounded in real-world construction experience and an understanding of how environmental conditions affect property value, operations, and redevelopment.

Consulting, Assessment & Planning

We provide environmental consulting, engineering, and real estate support that helps owners, buyers, lenders, and project teams understand environmental risk and plan realistic paths forward.

That includes Phase I and Phase II assessments, health risk evaluations, workplan development, and environmental real estate advisory services tailored to California’s regulatory landscape.

Construction, Cleanup & Infrastructure

Our construction and field crews implement remedial designs in the field—performing remedial excavations, UST and clarifier removals, system installation, and specialized soil and groundwater cleanup.

Consulting and construction staff work together from the start so that each recommendation is practical to build and operate at active facilities and redevelopment sites across California.
