Date of Spill Response Report prepared by Michael L. Foster and Associates on behalf of Crowley Petroleum Distribution. Work was conducted on June 15 and 16, 2010 and included field observations and screening, as well as hand excavation and removal. Prior to excavation, staining of the gravelly surface layer was within 40 feet of lake edge that is used for drinking water, although no sheening was observed during these activities.
Excavation depth ranged up to 18 inches at which staining was no longer evident and a silt layer was reportedly encountered. The horizontal extent was 17 by 16 feet. A total of approximately 8.5 cubic yards of contaminated soil was removed and treated.
Petroleum odors remained following excavation. Two test pits were excavated beyond the extent of the excavation(side opposite the direction of the lake). Odors were observed in one of the 2 test pits.
Confirmation samples contained up to 2,150 mg/kg GRO, 7.54 mg/kg benzene, 158 mg/kg toluene, 75.8 mg/kg ethylbenzene, 747 mg/kg xylenes, and 9,210 mg/kg DRO. |

Update or Other Action |
Email on today's date from Drinking Water Program stating that "We have discussed this issue and the consensus is that it is reasonable and precedented for the system to collect a sample of finished water to be analyzed for BTEX (Benzene, Toluene, Ethyl Benzene and Xylene) using EPA Method 524.2." It was also stated that they will communicate this requirement. |

Site Visit |
Site visit to observe monitoring well installation location and presence/absence of water in wells. MW-3 (closest to the lake) appeared to have sufficient water in it to be sampled based on observations made using a bailer. MW-1 did not appear to have sufficient water in it based on observation with bailer. MW-2 had a petroleum odor but no observations were made of the water level. |

Document, Report, or Work plan Review - other |
Receipt of draft Eureka Lodge Site Characterization Report. Eight soil borings were advanced around the ASTs with three completed as MWs. Ten soil samples were collected from the borings. Only two of the borings located south of the ASTs (SB02/MW-1 and SB-3) contained contaminant concentrations above cleanup levels with DRO up to 4,000 mg/kg at 9 feet bgs and benzene up to 18 mg/kg from a sample collected at 12.5 feet bgs. Further delineation to the south was not conducted per the lodge owners request. Only one of the three MWs contained groundwater. Groundwater encountered in MW-2 at 13.5 feet bgs contained detectable levels of DRO, but below cleanup levels. A surface water intake and a lake surface water sample contained detectable levels of DRO but below cleanup levels. (Note: the report CSM indicates that Ingestion of Surface Water Pathway is Incomplete which does not match with the ETM evaluation. This pathway should be considered complete. Also, only two PAH samples were collected and six compounds for each of these samples are considered rejected (five of these compounds are bioaccumulators, therefore, the Ingestion of Wild and/or Farmed Foods Pathway cannot yet be considered Incomplete as the report concludes). The report includes a memo from the laboratory providing a reasonable argument for the nondetected results that require qualification to be considered estimated low rather than rejected. Regardless of the qualification, we still do not know if these compounds would have been detected.) |

Update or Other Action |
Per a sanitary survey in 2015 by the DEC Drinking Water Program, it was discovered a new drinking water well had been completed at the property back in 2010. The location of the well house is approximately 100 feet south of the Lake adjacent to the east of Eureka Lodge; 100 feet west of the contaminated site. The well total depth is 105 feet bgs, but is perforated 20 to 23 feet bgs and is considered under the influence of surface water. This well is an ADEC regulated public water system (ID# 226397)and is the Lodge's current drinking water source. |

Site Characterization Report Approved |
On this date, ADEC received the 2017 Monitoring Report Eureka Lodge Mile 128 Glenn Highway, Alaska submitted by ERM and dated May 2018. MW-1, MW-3, surface water and the lodge public water system drinking water well were sampled. Additionally, forensic soil samples were collected. MW-2 could not be located and assumed graveled over. PAHs were not sampled from MW-1 due to low recharge. Groundwater samples from MW-3 did not contain detectable concentrations of contaminants. A groundwater sample from MW-1 contained DRO up to 3,700 ug/L, which is above the ADEC table C groundwater cleanup level of 1,500 ug/L. Two surface water samples were collected, one from the former well house location and one from the historic bankside location. These surface water samples contained detectable levels of DRO up to 220 ug/L, but did not contain detectable levels of BTEX and PAHs and therefore did not exceed TAH and TAqH AK water quality standards. Historically, the community used the unnamed lake as a drinking water source and there is at least one known surface water intake still in use on the lake. The Eureka Lodge groundwater drinking water well sample, collected inside of the well house to bypass the water treatment system, contained toluene up to 0.17J ug/L, which is well below ADEC table C groundwater cleanup levels and drinking water standards. Groundwater flow was not determined. |
