Problems/Comments

Fuel contamination of soil and groundwater found during owner site assessment in 11/1988. Possible sources are underground tanks and surface spills. Also spills of at least 100 gallons of waste oil, which at times has been found in drainage ditch on Fairbanks Street. Complaint 91-122 indicated that oil, batteries, and drums were dumped on property next to site before the Borealis Hotel was built. A soil vapor extraction/air sparging remedial system was installed in 1994, with subsequent declines in the groundwater contaminants. The contaminant plume had reached the University of Alaska Fairbanks (UAF) public wells, but has since reduced beneath cleanup levels to the north of Geist Rd and the UAF wells are no longer being used for drinking water.

1/14/2014	Document, Report, or Work plan Review - other	DEC reviewed the First Semi-Annual 2013 Groundwater Monitoring Report. Concentrations of GRO and DRO remain above cleanup levels in wells G-8, G-3, and off-property well G-5. Benzene remains above cleanup levels in well G-1R. All other groundwater wells and the UAF wells did not contain contaminants above cleanup levels. G-5 is the well with the highest concentration of hydrocarbons, with GRO detected at 15,200 ug/L and DRO at 3,800 ug/L.	Robert Burgess
2/27/2014	Meeting or Teleconference Held	DEC met with Chevron and their consultants for a project update and planning meeting. The remedial system has been decommissioned, with the exception of air sparge wells which will be decommissioned in 2014. Off-property wells that have not contained detectable contaminant concentrations for several sampling events will be decommissioned. DEC agreed that sampling frequency can be reduced from semi-annual to annual, and that the sampling UAF well influent and effluent sampling can also be reduced or eliminated, pending UAF approval. Off-property well G-5 was discussed as a major issue that could potentially prevent site closure in the future, however a decision was made to allow contaminants throughout the site to attenuate before further discussion of active remediation at this well.	Robert Burgess
11/17/2014	Document, Report, or Work plan Review - other	DEC reviewed the Annual 2014 Groundwater Monitoring Report. Concentrations of petroleum hydrocarbons in monitoring wells G-8 and G-5 have increased since the last sampling event, likely due to the unusually high water table elevation. The report notes that wells that are no longer needed for monitoring will be decommissioned in 2015.	Robert Burgess
2/24/2015	Meeting or Teleconference Held	ADEC project manager met with Chevron and ARCADIS via teleconference. Plans for the site in 2015 include decommissioning inactive monitoring wells and continuing with annual monitoring. In addition, the potential for contaminants remaining in soil to be released during dynamic compaction of a construction site a few miles away was discussed and Chevron agreed to monitor downgradient wells between the existing plume and the UAF water supply wells to ensure that the tremors do not mobilize contamination. Treatment options were discussed for off-property well G-5 which still contains relatively high concentrations of diesel range organics. If active treatment is employed at this well in the future, Chevron states it will likely be new injection techniques such as Plume Stop.	Robert Burgess
9/24/2015	Document, Report, or Work plan Review - other	DEC reviewed and approved the 2015 Groundwater Monitoring and Sampling Work Plan.
