Army training reservations contain vehicle wash
facilities where combat and other
equipment are washed after field maneuvers. During this process, sediments containing
significant concentrations of petroleum hydrocarbons accumulate in concrete sedimentation
basins. Conventional treatment methods to de
contaminate these sediments include landfill
disposal or land application. However, vegetative remediation systems may offer a cost
-
effective
alternative. A phytoremediation design that reduces petroleum hydrocarbons to acceptable levels
and is simple to

implement and maintain was developed for the Central Vehicle Wash Facility
(CVWF), Fort Riley, Kansas. This paper presents a brief outline of site characterization,
vegetation treatment system design, and complete results for a two
-
year study.
