Document, Report, or Work plan Review - other |
Nortech Groundwater Sampling Results, UIC injection well closure for 5855, and 5859 Aerofuel Place, Fairbanks, AK was received from EPA. The floor drains in the hangar and shop were formerly connected to on site septic systems. Groudwater samples were collected from two on site leachfields. Analytical results indicate that toluene concentrations in the septic groundwater slightly exceeded the Table C cleanup levels. Also, arsenic concentrations in the septic groundwater were above ADEC Table C cleanup levels. However, concentrations were only slightly above the accepted background concentrations in the Fairbanks area. The floor drains have been re-directed to a buried tank which will be pumped out. |

Update or Other Action |
According to the report, monitoring wells MW-1 and MW-2 were sampled according to the proposed work plan but MW-3 could not be located. MW-1 detected petroleum contamination but it was below the ADEC regulatory levels and MW-2 was nondetect. Since MW-3 was located in the former source area and historically had elevated levels of contamination, DEC requested to replace this well and sample for closure. Sent a letter to the RP. |

Update or Other Action |
DEC received from Rockwell Engineering a 2008 report for the installation and sampling of source area well MW-3. DRO and benzene were above cleanup levels at the time of sampling. No information has been submitted regarding the fate of the stockpile. This information has been requested by DEC. |

Document, Report, or Work plan Review - other |
DEC received the September 2010 Soil Stockpile Groundwater Monitoring Sampling Event Report. No work plan was submitted for this work. Report does not include information on how well MW-3E was installed or how the sampled soil was excavated for sampling. RP contacted DEC after comments from DEC were sent. RP is concerned with the amount of money that has been spent at the site and the need for closure. DEC indicated that a decision can be evaluated once the additional information requested is submitted to fill in data gaps. There are currently two coverall buildings on top of the formerly contaminated soil, therefore, additional sampling may be difficult. |
