Remedial Investigation at Travis Air Force Base
VENTURA, CA / The Remedial Investigation (RI) for 16 aqueous film forming foam (AFFF) sites included three phases of iterative field investigation tasks, for which where we performed project management, site-specific planning document development, field investigations, reporting, and support for community involvement.
Primary tasks include characterization of the vertical and lateral extent of PFAS impacts in soil and groundwater; source strength evaluation; Conceptual Site Model (CSM) development, and support for United States Army Corps of Engineers (USACE) and Travis Air Force Base for planning and communication with regulatory agencies and stakeholders.
The project required continuous coordination of chemists, geologists, engineers, and scientists, drilling operators, natural resources team, project biologists, data analysts, GIS analysts, contract managers, and accounting managers. Team members used all data to inform the site understanding, or CSM, and make recommendations on project activities.
Highlights
- ‘Exceptional’ rating in Contractor Performance Assessment Reporting System (CPARS) in all evaluation areas
- Presented at the 2023 Battelle Bioremediation Symposium in Austin, TX
- Presented at the RemTEC & Emerging Contaminants Summit in Westminster, CO
Services
- Chemical Engineering
- Geological and technical assistance regarding regulatory compliance and interaction
- GIS data analysis support
Challenges and solutions:
Project complexities included collection or data to determine off-Base impacts to private wells, complicated hydrogeologic framework, and biological requirements to protect the endangered species at Travis Air Force Base, requiring a very limited field season for intrusive work.
