挑战

The Defense 物流 Agency manages the global supply chain for the Army, 海军, 海军陆战队, 空军, 空间力量, 海岸警卫队, eleven combatant commands and various other federal agencies for the entire nation. This includes overall 管理 of a global supply chain that supplies 86% of the military’s spare parts and close to 100% of the fuel and troop support consumables. 像这样, DLA operates a network of facilities across the nation, handling both dangerous goods and 有害物质, and the conveyance of these materials to their destinations.

新黄金城

Since 2002, Apex Companies, LLC [Apex]/The Source Group, Inc. (SGI) (Apex-SGI), has provided an array of environmental engineering services at two DLA‑operated military fuel storage and distribution facilities located in 南加州.

Over the past five years alone, our work at these sites has included preparation of H&年代的计划, quality assurance project plans (QAPPs), 废物管理计划, 协调实验室活动, 网站评估, 补救措施设计, remediation system operation and maintenance (O&M), groundwater and monitoring and sampling services, and 合规 and permitting under numerous ongoing contracts.

我们已经完成了O&M of over ten separate remediation systems which utilize groundwater extraction and treatment, biologic treatment processes, 空气喷射, LNAPL复苏, thermal treatment and/or vapor extraction technologies. Tasks completed included site investigations, groundwater monitoring and sampling, public participation support and engagement, and reporting (over 200 reports are generated each year); and conducting work in accordance with DLA Facilities Management, 合规, and permitting requirements.

Our services also include providing thermal remediation support to remediate petroleum contaminated soil and groundwater at 9 areas of concern (AOC) located at the site:

  • Working in concert with thermal remediation technology specialists, Apex-SGI的工程师, 地质学家, and environmental specialists have completed the remediation of soil and groundwater at two former 2.1加仑容量体积, field‑constructed underground storage tanks (BFCUSTs) using steam injection and electrical resistance heating (ERH) methods. Thermal remediation systems are currently in operation at three additional BFCUST sites and preparations are underway for installation of similar systems at four more BFCUSTs.
  • As part this turnkey project, Apex‑SGI completed investigations to delineate the extents of the target remedial zones, prepared agency-approved 补救措施设计s and plans, installed the multi‑component treatment systems, and conducted remediation system O&M, and groundwater monitoring and sampling.
  • Thermal remediation required remediation personnel to be on-site 24 hours a day, including weekends. Apex‑SGI addressed this requirement in the project 管理 plan and then coordinated security access and a communication structure to ensure access to the site for multiple crews.
  • After approximately 12 months of active thermal remediation was completed, Apex‑SGI conducted rebound testing, soil matrix confirmation sampling, and soil gas sampling at the first two thermal remediation sites. The results of this confirmation testing and analysis was used as the basis for preparing detailed Remedial Action Completion Reports (RACRs) for review by DLA and submittal to State regulators.

结果

We have earned repeated accolades from successive DLA project managers. In its recent CPAR (federal government rating system), DLA ranked Apex-SGI’s 管理 at DFSP San Pedro as “Exceptional” in the areas of quality, 计划成本控制, 管理, 和法规遵从性. 移除超过260个,000 pounds of hydrocarbon mass at the two former fuel storage tanks, the completion of confirmation soil sampling to confirm that soil cleanup goals had been achieved, and post‑treatment soil gas surveying demonstrated that no residual hydrocarbons were present in shallow soil gas, the State Board agreed that the thermal remediation phase of remediation was complete.

Apex-SGI is currently responsible for the remediation of soil and groundwater at over 20 AOCs at the facility, with a goal to complete all active remediation by the end of 2025. At the completion of this project, 近500,000 cubic yards of contaminated soil and associated contaminated groundwater will be remediated.
