Environmental Construction & Remediation in California
Encon Environmental delivers environmental construction and remediation services that turn approved workplans and engineering designs into working systems in the field. Our crews support projects throughout California, including Southern California, the Central Coast, the Bay Area, and the Central Valley.
From remedial excavations and in-situ treatment to vapor extraction systems and infrastructure removal, our focus is on safe execution, clear communication, and regulatory compliance at operating and redevelopment sites.
- Implementation of soil and groundwater cleanup remedies.
- Installation and optimization of vapor extraction and treatment systems.
- Field services that support long-term monitoring, risk reduction, and closure.
Construction & Remediation Services for California Sites
Encon Environmental provides field implementation services that bridge the gap between design and completed construction. We work at active fueling facilities, industrial properties, and redevelopment sites where access, safety, and schedule all need to be carefully managed.
Our construction teams coordinate closely with consultants, engineers, and regulators to build systems that match approved environmental workplans. We understand the requirements associated with Phase III cleanup, UST and clarifier removal, and soil and water remediation under California regulatory programs.
- Remedial excavations and off-site soil disposal or treatment.
- Support for UST, waste oil tank, hydraulic lift, and clarifier removal.
- Trenching and installation of subsurface conveyance piping.
- Construction of treatment pads, equipment foundations, and utility connections.
- Backfilling, compaction, paving, and surface restoration following work.
System Installation, Start-Up, & Ongoing Field Services
Beyond one-time excavation projects, Encon installs, starts up, and maintains a variety of remediation and vapor control systems. Our crews implement designs for vapor extraction systems, bio-remediation and chemical injection programs, and groundwater treatment systems developed by Encon engineers or third-party consultants.
We also provide routine field services—sampling, system checks, and performance monitoring—that support long-term cleanup, risk management, and eventual site closure throughout California.
- Installation of vapor extraction and off-gas treatment systems.
- Construction of injection wells and implementation of bio-remediation or chemical injection.
- Installation and development of groundwater monitoring and extraction wells.
- System startup, troubleshooting, and optimization based on field data.
- Sampling, O&M visits, and documentation for regulatory reporting.
Working Safely at Operating Facilities Across California
Many projects involve construction and remediation at operating sites—retail fueling locations, fleet yards, warehouses, industrial plants, and mixed-use properties. Encon Environmental plans work to minimize disruption to business operations while maintaining strong safety performance.
We coordinate closely with facility staff, tenants, and other contractors to manage access and phasing, and we implement site-specific health and safety plans consistent with client and agency requirements.
- Site-specific health and safety planning and tailgate meetings.
- Coordination of traffic, access control, and work areas.
- Compliance with client, contractor, and agency safety programs.
- Clear communication of schedule, constraints, and milestones.
- Detailed field documentation to support regulatory and internal records.
