OMID ARZILI
Burbank
Summary
Experienced mid-level geologist with a strong background in Phase II environmental investigations and remediation. Holding a degree in Geology from California State University, Northridge, I am dedicated to advancing my expertise in environmental consulting, site assessments, investigations, and remediations. With three years at GSI Environmental and six months with Roux Associates, I have developed specialized skills in soil and groundwater sampling, subsurface drilling, lithologic analysis, site remediation, data tabulation and interpretation, and report writing. Proficient in executing complex investigation and remediation projects, including ensuring compliance with state and local regulatory frameworks, such as DTSC, USEPA, SCAQMD, and the Regional Water Quality Control Board.

Work History
Staff Geologist II
Roux Associates
Burbank
07.2025 - 01.2026
- Led Phase II investigation and remediation projects as field lead.
- Managed projects before, during, and after fieldwork by completing pre-field tasks, including correspondence with the project team and subcontractors; leading projects in the field; and tabulating data and drafting Phase II reports.
- Led drilling and well installation jobs, sampling events including soil sampling, groundwater sampling, and soil vapor sampling, as the field lead.
- Held discussions closely with project managers, seniors, and principals, and offered options and ideas to ensure project success.
Environmental Geologist I
GSI Environmental
Irvine
07.2022 - 07.2025
- Conducted comprehensive environmental risk assessments and Phase I ESAs at various sites across Greater Los Angeles County, Orange County, and San Bernardino County.
- Led various Phase II environmental investigations and remediation projects.
- Led drilling projects as the field lead, and tracked soil lithology to assess geological formations, saturated zones, and confining layers. Then, efficiently relayed information to the project team to ensure proper installation of the screening zone in the groundwater wells.
- Installed groundwater wells, soil vapor wells, and soil vapor extraction wells.
- Executed groundwater remediation projects via the injection of sodium permanganate and sodium bicarbonate.
- Executed soil and soil vapor remediation projects as field lead, including the installation of shallow and deep networks of soil vapor extraction wells, and oversight of connections made to the SVE system. Also led shallow and deep soil excavation projects, including confirmation soil sampling, and diligent field documentation.
- Performed soil, soil vapor, and groundwater sample collection, solely and with subcontractors.
- Familiar and proficient with SCAQMD rules and PM10 fugitive dust protective measures, including Rule 403, Rule 1166, and Rule 1466, and have conducted air monitoring utilizing all three rules.
- Tabulated and interpreted laboratory data for soil, soil vapor, and groundwater, to assess contamination levels and appropriate remediation strategies.
- Collaborated with multidisciplinary teams to develop and implement effective, site-specific environmental solutions, and ensure project success before commencing fieldwork.
- Provided daily, detailed reports and presentations to project managers, showcasing findings in the field, and recommending actions for future activities.
- Tabulated data tables from lab reports from multiple state-certified laboratories.
- Prepared Phase II reports for projects I led in the field, and for PMs on projects with which I was not directly involved in the field.
- Skilled at working independently and collaboratively in a team environment.
Research Assistant
CSUN
Northridge
12.2019 - 04.2022
- Planned and executed various research techniques, procedures and tests for U-Pb zircon dating of low to mid-crustal rocks focusing on growth of continental lithosphere during the Phanerozoic
- Collected research data through experiments conducted in a heavy machinery lab, a fume hood lab, and a microscope lab
- Microscopes include SEM, XRF, XRD, and IC-PMS
- Recorded clean and organized experimental notes, findings, and questions in laboratory notebook to analyze and interpret findings to ultimately resolve questions
- Worked collaboratively with our research team to investigate, identify, and coordinate data results, errors, and deviations from standards
Research Internship
Southern California Earthquake Center
Los Angeles
06.2021 - 12.2021
- This SCEC internship allowed me to learn and practice numerous old and new field methods of collecting field data, interpreting and creating geologic maps, and logging detailed notes into a field notebook
- 20 hours of field experience obtained through summer internship, most was spent conducting experiments in the lab and analyzing the results
- We were collecting lower-crustal granulite facies metamorphic rocks from the South-Eastern San Gabriels to conduct U-Pb radiometric dating techniques to understand the timing of shear deformation
- Met weekly with an internship cohort & advisor and collaboratively discussed project updates, positives and negatives, and future goals
