Services
A full continuum of environmental services
From first assessment to regulatory closure, every engagement is documented, defensible, and built to move complex Southern California sites toward redevelopment.
Additional Site Investigation
Data-gap analysis, delineation workplans, nested vapor probes, groundwater delineation, and CSM refinement, with responses to DTSC, LARWQCB, and CalGEM.
Remediation & Mitigation
RAWs and feasibility studies; SVE, ISCO, bioventing, and excavation; rebound testing, optimization, and closure reporting.
Vapor Intrusion Mitigation
Sub-slab depressurization, vapor barrier design, and verification monitoring for protective, regulator-ready outcomes.
Site Characterization
Conceptual site models, contaminant delineation, and risk-based screening that frame a clear path to closure.
CalGEM Well Reviews (CSWR)
Construction Site Well Reviews: well records review, re-abandonment scoping, and agency coordination.
Process
A clear path from first look to closure
Every project follows the same four phases, so you always know where the site stands and what the next defensible step looks like.
- 1
Assessment
We review site history, prior reports, and regulatory files to scope the right investigation the first time.
- 2
Investigation
Phase II sampling, boring logs, vapor and groundwater data collection, building the conceptual site model.
- 3
Remediation
SVE, ISCO, bioventing, or excavation — whichever approach gets to closure fastest and most defensibly.
- 4
Closure
Regulator-ready reporting and agency coordination through no further action (NFA) or closure.
