ENGINEERING PROJECTS

Currently vacant property
known as “Dr. Pickett”

Site Assessment, Groundwater Monitoring, and Excavation

EAR performed a site assessment and soil vapor extraction feasibility test, which indicated the best option would be the excavation of the impacted soil. We excavated petroleum impacted soil from the former gas station property and are currently performing groundwater monitoring.

Activities:

  • Site investigation
  • Excavation
  • Groundwater monitoring
  • Feasibility testing

Contract Data

Contract Amount: $350,000, through the state clean-up fund

Brazil Market

Site Assessment, Groundwater Monitoring, and Site Remediation

EAR conducted a site assessment at Brazil Market in 1998 and implemented soil vapor extraction, groundwater treatment, and air sparging remediation technologies following feasibility testing. We have nearly reached the clean-up goals for this site and have completed confirmation borings.

Activities:

  • Site investigation
  • Feasibility testing
  • Groundwater monitoring
  • System operation and maintenance
  • Remediation via vapor extraction, groundwater treatment, and air sparging
  • Confirmation boring

Contract Amount: $750,000, through the state clean-up fund


Camp Pendleton

Groundwater Monitoring, Site Remediation, and System Operations and Maintenance

EAR has been conducting environmental activities at the Camp Pendleton Marine Corps Base since March of 2004. With four different sites on the base, EAR has been effectively managing groundwater monitoring, system operations and maintenance, and remediation activities. Contamination has been consistently reduced using techniques such as vapor extraction, LNAPL removal, and biosparging.

Activities:

  • System operation and maintenance
  • Groundwater monitoring
  • Low flow sampling
  • Remediation via vapor extraction and biosparging

Contract Amount: $1,907,648, through the Navy


Nix Automotive

Phase II Site Assessment and Site Remediation

EAR was contracted to conduct site assessment and remediation at Nix Automotive in 1997. EAR initially utilized high vacuum dual-phase extraction to treat the soil and groundwater contamination that was found during the site investigation, but following low recovery rates we chose to implement the more aggressive approach of in-situ chemical oxidation. During this project, we employed membrane interface probe (MIP) technology to help us better characterize the subsurface and serve the client.

Activities:

  • Site investigation
  • Groundwater monitoring
  • Remediation via dual-phase high-vacuum extraction and in-situ chemical oxidation
  • Subsurface characterization using MIP technology

Contract Data

Contract Amount: Up to $1,500,000, through the state clean-up fund


Carat LLC

Phase I and II Environmental Assessment

In February 2006, Carat LLC contracted EAR to perform Phase I site assessment on two vacant lots. Based upon the results, the contract was expanded to include Phase II site assessment, after which EAR determined that the low concentrations of pesticides encountered required no further corrective actions.

Activities:

  • Phase I site assessment
  • Phase II site assessment
  • Soil sampling

Contract Amount: $6,730, through Carat LLC
