Environmental Science and Geology

Our mobile remediation unit in operation. We provide environmental remediation services in Northern California.

Minimizing the risks and costs associated with deleterious environmental conditions can be a significant concern for property owners and developers. Our professional team of Geologists, Environmental Scientists, and Field Technicians has worked for the last 25 years to build strong relationships with public health and water quality staff throughout Northern California. Over this period, our team has overseen the closure of more than 150 contaminated sites spanning waste oils, fuels, metals, wood preservatives, solvents, and caustic chemicals. You will benefit from the use of our Geoprobe drilling rig, innovative cleanup contracts, and fleet of remediation equipment. Our projects have been reviewed and approved by Regional Water Quality Control Board staff, County Environmental Health agencies, and the US Environmental Protection Agency.

Our environmental compliance and remediation services include:

  • Environmental due diligence - Phase I/II Environmental Site Assessments
  • Soil and groundwater investigation and remediation feasibility/design
  • Air, surface water, and groundwater monitoring services
  • Remediation system installation and operation


Our remediation equipment includes:

  • Eight stand-alone ozone/hydrogen peroxide injection units
  • A trailer mounted high vacuum dual-phase extraction (HVDPE) unit with thermal oxidizer
  • A skid mounted soil vapor extraction unit
  • A variety of submersible groundwater pumps
  • A custom self-contained truck-mounted Mobile Remediation Unit (MRU), which can deliver ozone, oxygen, hydrogen peroxide with or without shore power
