Co-inoculated Trees with Multiple Endophytes for Mixed Wastes Soil & Groundwater Site in Fairbanks, AK
Prime Contractors: PPCU and Trihydro
Intrinsyx worked with its prime contractors to design a phytoremediation system to address overlapping groundwater plumes of chlorinated solvents as well as petroleum hydrocarbons (TPH, DRO GRO benzene). The team developed a planting scheme based on the locations of the plumes. Where both chlorinated solvents and petroleum hydrocarbons were present, trees would be co-inoculated with both PDN3 (chlorinated compound degrader) and PD1 (petroleum hydrocarbons degrader).
Holes were bored through soil and through asphalt and 700 trees were augered in 8 feet deep. Local balsam poplar stock were sourced to be best adapted to the environment.
