Case Studies

Get more information about some of our recent projects and learn more about our approach in each of the case studies below.

Case Study 1: Remediation system O&M at a major oil company

Managed and performed site remediation system operations and maintenance program for one of the largest oil companies in California.

Tasks included:
Weekly system monitoring, servicing and retrofitting of system controls and components
Collection of soil vapor and ground water samples
Database management
Monthly progress reports to the client
Quarterly reports to the public agency

System and program delivered over 50% reduction in the operating costs of the system while increasing remediation system operating time and contamination recovery by 40%.

Case Study 2: Modification for higher efficiency at a large refueling facility

Integral evaluated a remediation system and implemented modifications to maximize system efficiency at a large refueling facility.

Instead of recommending a larger conventional ground water pump and treatment system to replace an inadequately size unit installed by a prior contractor, Integral designed and conducted a pilot test to demonstrate that dual phase extraction technology was more feasible and effective for the constraints of the site.

Based on the pilot, Integral re-designed the system with the dual phase extraction technology, resulting in substantial cost savings and 80% efficiency improvement over the existing system.

Case Study 3: Design and O&M of complex remediation for severe soil contamination

Designed, implemented, and conducted operations and maintenance program on a complex remediation system at a former manufacturing facility with severe soil contamination by chlorinated volatile organic compounds from 99 UST’s.

The original manufacturer’s design was discovered to be sub-optimal because the complexity of the release and wide range of constituents.

Extensive field based system re-design and retrofit was successfully performed by Integral.

Case Study 4: Design and construction of complex ground water extraction/treatment system

Design and construction of a complex ground water extraction and treatment system design to remediate a large plume of free-phase and dissolved-phase hydrocarbon, solvent, MEK, and acetone for a major industrial manufacturing facility.

Tasks Included:
Water treatment involving phase separation
Computer controlled multi-cycle air stripping
Carbon absorption
Hydrocarbon vapors treated by thermal and catalytic oxidation

Case Study 5: Design, construction, O&M, and monitoring of Superfund site

Design, construction, operation, maintenance, and monitoring of soil vapor and ground water extraction remediation systems for the Pacific Coast Pipeline Superfund site in Fillmore, California.

Tasks Included:
Ground water treatment with a 220 gpm system utilizing granular activated carbon filtration and free product phase separation.
Extracted hydrocarbon vapors treated by a 1,000 cfm thermal/catalytic oxidizer.

Case Study 6: Large scale cleaning and demolition of decommissioned tanks

Performed on-site management of large scale cleaning and demolition of decommissioned tanks from a former oil refinery.

Tasks Included:
Special considerations for environmental hygiene due to the close vicinity of single-family residences and an elementary school.
Monitoring of contractor health & safety meetings
Collection of ambient lead monitoring
Performance of confined space permit air sampling
VOC/Odor/Visible dust monitoring
Inspection of cleaning activities prior to disposal of dismantled tank casing
