Site Characterization Report Approved |
Report covering 2007 activities approved this date. Two tanks were located at the Birch Lake Storage area. Samples collected at the South Tank did not show contamination, however samples collected at the North Tank showed contamination to 15 feet bgs. Additional investigation needed. |

CERCLA SI |
2008 ROST SI report approved this date. 37 probes were installed. 5 primary samples and 1 duplicate were collected. 1 sample showed elevated concentrations of DRO (1800 mg/kg), Chromium, arsenic, 1,2 dibromoethane, and methylene chloride. Contamination was found only at Tank 1 (north) and not at Tank 2 (south). Additional investigation will be conducted in 2010-11. |

Site Visit |
Joint site visit by ADEC, DNR, USACE, and FES. The site had 2 ASTs. One of them does not need further investigation per the prior data. The other one does need further investigation. The site is relatively flat and is characterized by compacted gravel. No obvious signs of contamination were observed, but there is potentially fuel contamination below ground. Work is planned for the near future to include test pitting and/or excavation from 0-15 ft. Although no groundwater monitoring wells are planned, I requested that the camp drinking water well on site be tested. The camp drinking water well is down gradient of the site and is potentially shallow as evidenced by discoloration likely due to the presence of tannins as a result of its close proximity to the lake. |

Update or Other Action |
The following contaminants were found in soil beneath the pesticide containers above ADEC cleanup levels: 4,4'-DDD, 4,4'-DDE, 4,4'-DDT, chlordane, heptachlor, 1,2,4-trichlorobenzene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, ethylbenzene, and xylenes. Work on site has stopped and the responsible party will determine a disposal method for the stockpiled soil and a work plan for the pesticide contaminated soil still in the ground. |

Removal action is complete. Next step is likely a geophysical study of the extent of buried debris. |

Update or Other Action |
A geophysical investigation has been completed. at Birch Lake. It appears that they delineated the extent of the burial pit and that it extended between Tank 1 and Tank 2. CRREL needs to process that data and will provide a figure showing the geophysical results that we can use for estimating the amount of potentially hazardous debris and soil that needs to be excavated. |

Document, Report, or Work plan Review - other |
Reviewed and approved the report titled: 2017 Source and Contaminated Soil Removal Report Final (Revision 1). The planned work for Birch Lake was to excavate petroleum contaminated soil that was remaining at the footprint of aboveground storage tank (AST) #1 only - AST #2 was previously investigated and no further action is planned. During the work, debris including domestic waste, crushed 55-gallon drums, and pesticide cans dating to the 1950’s containing dichlorodiphenyltrichloroethane (DDT) and chlordane were encountered. Additional removal action site investigation (RA/SI) activity is warranted. |

Per B. Astley: the site is still eligible for FUDS depite the DDT cans. IF the groundwater is contaminated and IF has migraed to AF property adjacent - have no access to AF property. Geophysical data suggests metal anomaly larger than empty DDT cans. Going to do additional characterization. Plan is to sample the groundwater in summer 2019. |

Meeting or Teleconference Held |
Met with the DNR and the USACE on projects. The USACE is going to evaluate FUDS eligibility after finding the pesticide contamination - site should be eligible. This process may take two years. In the interim, the DNR will not issue any permits to dig on site which prevents access to the contamination located belowground. There appears to be a historic dump and berms which have debris - may be an indicator of the magnitude of the historic dump. However, we are able to continue looking at the groundwater contamination in the interim as it was part of the original scope of work. |

Site Characterization Report Approved |
FUDS conducted a removal action near the former Tank 1 to remove and dispose of all petroleum contamination at the site related to the use of the two former tanks and appurtenances. A total of 1,907 cubic yards of comingled pesticide and petroleum contaminated soil were excavated and disposed at Moose Creek Facility. The 2021 excavation encompassed the Tank 1 source areas identified by laboratory sampling in the previous investigations. Bedrock was encountered throughout the excavation and no groundwater was observed during this removal action or at any time throughout the project. A total of 27 primary laboratory confirmation samples were collected from the base and sidewalls of the excavation. Samples were analyzed for RRO, DRO, GRO, VOC, EDB, PAH, pesticides, PCB, and RCRA metals. No PCB were detected in the confirmation samples. All RRO, DRO, GRO, VOC, PAH and RCRA metals, except for arsenic, were well below the most stringent cleanup levels. Following the excavation the site was re-seeded. Collocated pesticide contamination is under the associated site Eielson AFB (SER-2) (DP55) Birch Lake. |
