CES assesses property, investigates and cleans up contaminated soil and groundwater, and monitors and maintains landfills and remediation systems. Our own engineers, geologists, scientists and field crews carry each site from the first Phase I to final regulatory closure.
CES employs its own engineers, geologists, scientists, project managers and field crews, and holds a California Class A and HAZ contractor license. We perform the consulting and the field construction and operations ourselves, so the people who scope your project are the people who finish it.
About CES
Phase I and Phase II ESAs for property purchases, refinancing and development, written so you can price and schedule the transaction.
Site assessment →Characterization, risk evaluation, cleanup planning and case management with DTSC and the Regional Water Board through closure.
Investigation and closure →SVE, multi-phase extraction, air sparging, groundwater treatment, chemical oxidation and excavation, built and run by CES crews.
Remediation →Monitoring, sampling, system maintenance and repair, and compliance reporting for active and closed landfills.
Landfill services →Groundwater, soil vapor, landfill gas, air and water sampling programs, well work and equipment installation.
Monitoring →Task order delivery for school districts, counties, Caltrans, ports and federal agencies.
On-call services →Dry cleaner site taken from assessment to a DTSC No Further Action determination for unrestricted land use, with approximately 99% reduction across soil, groundwater and vapor.
Two SVE systems on 22 wells designed, built and operated by CES for Phillips Edison & Company. PCE down 99.6% at the historic hotspot.
Prime since 2013 across 13 active and closed landfills, including Prima Deshecha, Olinda Alpha and Frank R. Bowerman.
We assess, design, build, operate and close. No hand off between a consultant and a separate contractor, and no markup on subcontracted field work.
CES crews sample, construct and maintain, which means faster mobilization, consistent sampling quality and direct control of schedule and safety.
Our largest public contracts have been renewed and re-won over many years, the clearest measure of performance an agency can give.
An owner of the company leads each engagement and a licensed engineer signs each regulatory deliverable.
Every scope starts with the decision you need, whether a clean transaction, a closure letter or continuous compliance, and leaves out work that does not move toward it.
Time and materials for consulting and on-call work, fixed price for recurring monitoring and maintenance, lump sum for construction where procurement requires it.
Tell us the decision you need to make and when. We will tell you what it takes to get there and who on our team will carry it through.
