Former BJ Services Company Facility, Ventura, CA

Weston performed soil and groundwater remediation and closure of a former BJ Services Company facility affected by petroleum hydrocarbons and enabled its reuse for the benefit of the local community.

In 2013, oilfield service company Baker Hughes retained Weston to complete ongoing remediation activities at a former BJ Services facility in Ventura, CA. Baker Hughes wished to expedite completion of remediation activities and regulatory closure of the inactive site to facilitate sale of the property.

Soil and groundwater at the project site were impacted by historical releases of petroleum hydrocarbons from underground storage tanks, vehicle maintenance, and chemical storage and handling at seven separate areas of interest. Light non-aqueous phase liquid (LNAPL) was also present in groundwater monitoring wells. Remediation of soil and groundwater was achieved by a combination of LNAPL recovery and soil vapor extraction. Remediation activities were performed between 2013 and 2015.

Confirmation soil vapor sampling and groundwater monitoring were performed in 2016 to verify that the cleanup goals were achieved. The Ventura County Environmental Health Department approved the closure sampling report and is in the process of issuing a No Further Action letter for the site. Weston oversaw removal of all remediation equipment and wastes from the site. Completion of remediation activities allowed Baker Hughes to sell the property that has since been put back into beneficial use by the new owner.
