Free Product Recovery System Kinder Morgan Site
A JP-8 fuel release resulted in a very large free phase hydrocarbon plume beneath the bulk fuel facility managed by a tenant fuel contractor at MCAS Yuma. Upon discovery, the tenant fuel contractor hired a large firm to characterize and remove the free product. A series of monitoring wells were installed and free product recovery efforts began and continued for a period of 6 months. During that time, approximately 15 gallons of product were removed from the subsur-face. MCAS Yuma was not satisfied with the remediation progress. As a result, GCE was awarded the contract to characterize and remove the free product from the site.
Ms. Stacy Gutierrez, P.E., C.I.H., supervised the completion of following project tasks ahead of project schedule:
♦ GCE installed an extensive monitoring well network to delineate the lateral extent and thickness of free phase hydrocarbons at the site.
♦ GCE designed and installed a free product recovery system consisting of in-well separator pumps, which discharge to an above ground- double walled storage tank.
GCE has successfully removed 40,000 gallons of free product from the subsurface. GCE went above and beyond expectations by including, within the scope of work, the identification of the responsible party. Using geophysical data, GCE delineated the topography of the clay layer beneath the site. This informa-tion was used in conjunction with groundwater flow data to successfully identify the source of the product plume. Identification of the source placed the burden for the next phase of remediation on the responsible party, providing a significant cost avoidance to MCAS.
Marisol Canales, P.E. was instrumental in providing additional cost savings in this project. Ms. Canales ensured that the recovered product was free from groundwater, thus allowing the fuel to be recycled with the on-base military fuel contractor. This non-scope task not only provided a cost savings to MCAS, but also maintained compliance with the waste minimization program requirements for MCAS.
This project was completed on time and under budget as direct result of GCE’s full service capabilities. This project provides a clear example of GCE’s capabili-ties with respect to groundwater investigations, remediation system design and operation, and pollution monitoring.
