4/3/2006 Report or Workplan Review - Other The ADEC received 1999 & 2000 post treatment reports from ASR. The reports show that ASR received and successfully treated 92.81 tons of contaminated soil in 1999 and 125.2 tons in 2000. Donald Seagren
4/4/2006 Update or Other Action An ADEC communication with a previous consultant, Gregg DuBois, indicates additional site assessment work is required to determine extent of remaining plume. Mr. Dubois intends to send ADEC copies of reports. Donald Seagren
4/4/2006 Underground Storage Tank Site Characterization or Assessment The ADEC reviewed the Corrective Action Report for Facility No. 3308, dated October 2, 2000 submitted by the IT Group and received by ADEC on this date. In August 2000, remaining contaminated soil was excavated from the area of the former UST and a trench was excavated to evaluate the extent of contamination. At the former UST, where soil contamination was visually observed at approximately 6 feet bgs., 100 cubic yards of contaminated soil was removed. To evaluate if soil contamination continued off property, a trench was excavated 15 feet away from the area, perpendicular of the former UST. Soil contamination was encountered down to 12 ft. bgs. Excavation was stopped at 12 feet bgs. due to the size of the excavator and its inability to remove a compacted soil layer. It was not determined whether the compacted soil layer represented the beginning of bedrock or a glacially compacted soil layer. Soil samples taken from stockpiles created during excavation activities from the area of the former UST and the trench contained DRO up to 2,390 mg/kg. The soil stockpile was later treated offsite. No confirmation analytical soil samples from the depths of the investigation were taken. Groundwater was not encountered. Grant Lidren

11/1/2016 Report or Workplan Review - Other Reviewed the Work Plan for Release Investigation, dated October 19, 2016 for the Begich Towers site. Soil and potentially water samples will be collected from four soil borings advanced. Joshua Barsis
2/20/2017 Report or Workplan Review - Other Reviewed the report titled Release Investigation, dated January 31, 2017 for the Begich Towers site. The requested field effort was completed on November 22, 2016 and consisted of advancing four soil borings (B1 through B4), three of which were completed as temporary groundwater monitoring wells (TWM1, TMW2, and TMW3), and collecting soil and water samples as appropriate. A temporary well was not installed at the location of Boring B4, the upgradient well, because groundwater was not encountered to a depth of 27 feet below ground surface (bgs). Groundwater was encountered in the other wells at about 18 feet bgs. Analytical soil and water samples were submitted for one or more of the following: gasoline range organics (GRO), diesel range organics (DRO), residual range organics (RRO), benzene, toluene, ethylbenzene, and xylenes (BTEX), volatile organic compounds (VOCs), and/or polycyclic aromatic hydrocarbons (PAHs). The soil samples collected from borings B1 through B3 exhibited levels of DRO between 365 mg/kg and 1,940 mg/kg, all of which exceed the soil migration-to-groundwater (MTG) cleanup level of 230 mg/kg. Additionally, naphthalene was present in the sample collected from Boring B2 at 0.0472 mg/kg, which slightly exceeds the cleanup level of 0.038 mg/kg. The samples collected from Boring B4 did not exhibit contaminant concentrations in excess of ADEC cleanup levels. DRO was identified in all of the groundwater samples between 10.5 mg/l and 31.5 mg/l, all of which are above the Table C groundwater cleanup level of 1.5 mg/l. The sample collected from TMW3 exhibited a level RRO at 3.97 mg/l, above the cleanup level of 1.1 mg/l. The sample collected from TMW1 was analyzed for PAHs and exhibited levels of benzo(a)anthracene, benozo(a)pyrene, benzo(b)fluoranthene, benzo(g,h,i)perylene, dibenzo(a,h)anthracene, indeno(1,2,3-c,d)pyrene, and naphthalene above the Table C groundwater cleanup level. ADEC requested a work plan for further characterization by May 1, 2017. Joshua Barsis
4/24/2017 Report or Workplan Review - Other Reviewed the Work Plan for Additional Release Investigation Activities, dated April 13, 2017 for the Begich Towers site. Proposed activities include advancing two soil borings that will be completed as groundwater monitoring wells, and collecting soil and groundwater samples as appropriate. Joshua Barsis
4/30/2018 Report or Workplan Review - Other Reviewed the report titled Additional Release Investigation Activities, dated March 14, 2018 for the Begich Towers site. The 2017 field effort consisted of advancing three soil borings, all of which were completed as groundwater monitoring wells, and collecting soil and water samples from the borings and wells as appropriate. Boring B5 (Well B5MW) was completed within the former UST excavation area. Borings B6 and B7 (Wells B6MW and B7MW, respectively) were installed downgradient of the former excavation, across Kenai Street. Concentrations of diesel range organics (DRO) was present in Boring B5 up to 648 mg/kg, which exceeds the Method Two Migration-To-Groundwater (MTG) soil cleanup level; however the water sample collected from Well B5MW had a concentration of DRO at 454 µg/l, which is below the Table C groundwater cleanup levels. None of the samples collected from Borings B6 or B7 exhibited contaminants in excess of applicable ADEC cleanup levels. There was not sufficient water in Wells B6MW or B7MW to collect a water sample. ADEC requested a work plan to sample Wells B5MW, B6MW, and B7MW semi-annually during the 2018 field season; once in the spring and again in the fall. Joshua Barsis
6/15/2018 Report or Workplan Review - Other Reviewed the Work Plan for Groundwater Monitoring, dated June 05, 2018 for the Begich Towers site. Proposed activities include biannual groundwater monitoring at three monitoring wells (B5MW, B6MW, and B7MW). Joshua Barsis
