MS; Three samples were taken in the Moose Creek neighborhood by Timmons and Noland. The General Store, the Al Cory Dr. residence, and a neighbor's house well were all sampled for VOCs, EPA Method 502.2. Date indicates actual date of sampling. Samples were taken from the well-pump located in the Al Cory Dr. house basement. A strong odor of hydrocarbons was noted and the water exhibited a yellowish-orange tint. |

ADEC received the analytical results from the groundwater sampling that occurred in June 2003. MW-9 had levels of 254 ppb benzene, MW-5 had levels of 221 ppb benzene and MW-26 (located next to the store's septic system) had 520 ppb benzene. The Altig's residence well (50' bgs) and pond that is used by the neighborhood children as a swimming hole were both non-detect. |

Received 2004 Annual Report for Moose Creek General Store. MW-26 showed benzene cont. at 766 ppm and EDB at 9.64 ppm. Drinking water wells (WW-1 and WW-2) were sampled and determined to be non-detect for GRO, BTEX and EDB. |
Deborah Williams |
| 8/3/2004 |
Update or Other Action |
ADEC drafted a letter to the RP making comments on the 2004 Annual Report for Moose Creek General Store. Also, ADEC stated the minimum requirements for groundwater sampling at the site would be sampling drinking water wells (WW-1, WW-2, and A-50) annually for BTEX using EPA Method 524.2. In addition, these wells should be sampled for EDB using EPA Method 504. The monitoring wells (MW-26, MW-9, and MW-25) should be sampled annually for GRO/BTEX using AK Method 101/8021. In addition, MW-9 should also be sampled and analyzed for EDB using EPA Method 504. After two years of data have been collected, the data can be evaluated for trends and a possible NFRAP determination could be issued. |

Update or Other Action |
ADEC received sample results from NORTECH for the samples collected from the drinking water wells on September 22, 2005 at the Allen's (WW-2) and the Altig's (A-50). Both of these wells were non-detect for BTEX using EPA method 524 and EDB using EPA method EPA method 504. |

ADEC received sample results from 2006 groundwater sampling event. The sampling event involved the sampling of WW-2 and A-50 for BTEX using 524.2 and EDB using Method 504 and GRO/BTEX for MW-26. The drinking water wells WW-2 and A-50 were non-detect for BTEX and EDB. MW-26 had 18.8 ppm GRO, 138 ppb benzene, 4.9 ppm toluene, 1.11 ppm ethylbenzene and xylenes were below ADEC cleanup levels. |

Update or Other Action |
Meeting with supervisor to discuss future remediation requirements for the site. According to the file, the primary pathways of concern at the site appear to be the Vapor Intrusion Pathway and the Groundwater Ingestion Pathway. The two drinking waters on site are WW1 and WW2 and are 60 feet deep. One downgradient well exists offsite on the Altig's residence is approx. 50 feet deep. WW1 was sampled in 94, 95, 03, and 04 and the results have always been non-detect for GRO and BTEX. WW-2 has been sampled in 03, 04, 05, and 06. The samples were non-detect for GRO and BTEX. In 05 and 06 the sample from the well was analyzed for EDB and was non-detect. A-50 drinking water well is located further downgradient and was sampled in 03, 05, and 06. All the samples have in non-detect for GRO and BTEX. In 05 and 06, the sample from the well was analyzed for EDB and was non-detect. For evaluating the Vapor Intrusion Pathway for the residences within in the plume area, indoor air samples were collected in 03 and 04. The highest result was 3.7 ug/m3 in 03 from the Allen's property. The levels exceed EPA screening levels for indoor air but could be attributed to background levels.
The groundwater plume appears to be stable and confined to the property which includes the rental property adjacent to the store. |

Proposed Plan |
DEC proposed a plan for RP to obtain site closure- sent letter in response to RP's request. At minimum, wells not intended for future use need decommissioned, long term monitoring plan needs maintained, ICs must be established including possible COBC, deed notice. See letter. |

Site Visit |
Met Al Samuel at site to survey monitoring wells, sparge wells, and vapor extraction wells. Found 8 monitoring wells, 11 vapor extraction wells, and 5 sparge wells. Many wells were not found and were probably previously decommissioned, covered, or destroyed by plowing. Discussed well decomissioning and groundwater monitoring with Al. |

Update or Other Action |
Contacted by owner to discuss treatment being installed on drinking water wells at the site by the Air Force due to the Moose Creek plume of perfluorinated compounds. Discussion with the DEC project manager about this treatment indicated any petroleum that might be present would be taken care of by the treatment system. The owner of the Moose Creek General store plans to sample the monitoring wells around July 1, when they are most likely to be thawed. Drinking water well testing will occur later due to limited funding. |

Update or Other Action |
DEC term contractor and staff inspected monitoring wells at the site, collected samples from two downgradient monitoring wells (MW-6 and MW-9), and attempted to sample MW-25 but could not find it. Additional wells were checked but several were frozen (MW-14 and MW-21). Other wells could no longer be found. A second round of groundwater sampling is planned for September. |

Document, Report, or Work plan Review - other |
A groundwater monitoring report was submitted by the contracted consultant, Shannon & Willson, for sample efforts in May and September 2021 for three groundwater monitoring wells located on site (MW-26, -9, and -14). The sample results shown that gasoline range organics (GRO), diesel range organics (DRO), 1,2,4-trimethylbenzene, 1,2-dibromoethane, 1,3,5-trimethylbenzene, benzene, ethylbenzene, naphthalene, and total xylenes remain above the DEC Groundwater Cleanup Levels at the source monitoring well (MW-26)in May. Many of the same analytes were also above the DEC Groundwater Cleanup Levels in September. An obstruction in MW-14 prevented sample collection in May 2021, but was successfully sampled in September, resulting in results that were mostly below the detection levels. Sample results for m,p-xylenes, o-xylenes, total xylenes, and naphthalene were flagged as estimated concentrations in this sample. |

Document, Report, or Work plan Review - other |
Moose Creek General Store Groundwater Sampling report received by DEC for a sample effort conducted in September 2022. Work was completed under the Amendment Two of the NTP21*472 on a Term Contract. Three groundwater monitoring wells were sampled to assess remaining petroleum contamination and the data was compared to historical data to review seasonal trends. Characterization of the investigation-derived waste purge water from sampling was analyzed for the presence of per- and polyfluoroalkyl substances (PFAs) as the store property is within the known groundwater plume for PFAs that originates from offsite. Sample results from MW-26 had diesel range organics (DRO) and gasoline range organics (GRO) above groundwater cleanup levels. The volatile organic compounds exceeding groundwater cleanup levels in all three sampled wells (MW-26, MW-5, MW-9) included 1,2,4-trimethylbenzene, benzene, and total xylenes. Trend analysis of MW-9 furthest downgradient of the source area did not have sufficient sample data for winter months and a complete suite of analytes to determine whether there were significant seasonal trends. |

Document, Report, or Work plan Review - other |
DEC reviewed a revised copy of the Moose Creek General Store Groundwater Sampling report submitted as a partial report on contracted work to sample groundwater at MW-5, MW-9, MW-26 during June, September, and December 2023 to gather information on contaminant levels across the seasons to compare with past sample results. |
