Underground Storage Tank Site Characterization or Assessment |
Sent letter requiring Phase II Site Assessment to determine full horizontal and vertical extent of remaining contamination. ADOT&PF reuested sampling of a drinking water well within 500 feet of the site to be included in the assessment. If previous reports and data can be located that provide satisfactory data on residual contamination, then the additional assessment will not be required or can be scaled back. |

Underground Storage Tank Site Characterization or Assessment |
ADEC received a May 10, 2006, Workplan for Planned Exploration, from Rory Galloway who is a consultant with G-Logics, Inc. Reviewed work plan for additional site assessment. Provided comments for inclusion in final work plan that included: site map, minimum of 2 GW samples from test pits and sampling public DW well. Coordinated with ADOT&PF and will await their comments prior to approving work plan. Work to be done the end of June 2006. |

Document, Report, or Work plan Review - other |
Reviewed the Soil and Groundwater Sampling Report, dated September 26, 2010, from G-Logics. To further characterize the presence and/or extent of subsurface contamination for the site, four soil borings were advanced and developed into groundwater monitoring wells. The soil boring sample results indicated that GRO, Benzene, Toluene and Ethylbenzene soil contamination remains in the subsurface at nine feet below the ground surface from the soil boring taken just south of the former UST location. The groundwater samples taken from this soil boring indicated that GRO, DRO, Benzene and Total Lead groundwater contamination remains in the groundwater. EDB and EDC were not detected in the groundwater sample taken within this monitoring well. The results of the drinking/potable water well survey indicated one onsite drinking water well approximately 50 to 60 feet south of Trident Airport Building and approximately 650 feet south of the contaminated monitoring well. This drinking water well is currently not being used as a drinking water source. |

Reviewed the Groundwater Sampling Report, dated October 25, 2011, from G-Logics. On August 15, 2011 the four existing groundwater monitoring wells and the one supply well was sampled. Only monitoring well GL-4 located just south of the former UST location detected Benzene above the groundwater cleanup levels at 0.0327 mg/L. The other three monitoring wells and the supply well did not detect any of the analytes in the samples taken. The groundwater was flowing towards the south at depths of 6.06 to 6.74 feet below ground surface. A drinking/potable water well survey was conducted within 1,000 feet of the former UST location, and none were discovered. The area businesses were also contacted and confirmed that all the business do not have potable water supply wells and that all potable water is brought into the offices from an offsite source. |

Cleanup Complete Determination Issued |
The cleanup actions to date have served to excavate and adequately reduce contaminant concentrations at this site. Contamination remains on site in subsurface soil and groundwater above established default cleanup levels; however ADEC has determined there is no unacceptable risk to human health or the environment. The most current soil sample analytical data reported GRO, DRO, benzene, toluene and ethylbenzene contaminations exceeding the applicable soil cleanup levels, within the former underground storage tank location. Any proposal to excavate, transport, move, treat, and/or dispose of residual contaminated soil at this “site” requires prior ADEC approval. Off site public water service is provided to this property. Water wells may not be installed on this property without the prior notification and approval of ADEC. All groundwater monitoring wells associated with this project must now be properly decommissioned in accordance with ADEC’s November 2011 Monitoring Well Guidance. The unused water supply well located south of the Trident Seafoods Building should be also be properly decommissioned in accordance with Alaska Drinking Water regulations. |
