Problems/Comments
The tank farm is located approximately 50 feet west of the elementary school and 350 feet west of the Kuskokwim River. There is a 3.5-foot-high gravel dike and liner around the tanks. The tank farm consists of two vertical, welded steel, single wall, BIA style tanks with removable tops. Both of the tanks have a capacity of approximately 8,000 gallons. The ASTs are supported on 8-by-8-inch timbers with 2-by-12-inch planking. The timbers and planking supporting the ASTs within the berm area were flooded because of precipitation retainment by the berm. A sheen was noted on open water within the berm area. Historically, excess water from this berm area was pumped to the nearby road surface to prevent overflow. Vegetation was growing within the lined bermed area. One soil sample was collected at 2 feet bgs, downslope from the AST farm main valve assembly. GRO concentrations were 1,500 mg/kg and DRO concentrations were 20,000 mg/kg. Site has been changed from 2402.42.001 to 2402.38.001

| 12/2/2008 | Exposure Tracking Model Ranking | Initial ranking with ETM completed for source area id: 74342 name: ASTs | Grant Lidren |
| 9/29/2009 | Site Visit | An initial site visit, performed by SLR, was completed on September 28 & 29 2009 before site work scheduled for the week of October 26, 2009. The only known drinking water well was located 500 feet away from the tank farm. Two upright tanks were discovered at the site inside an unlocked, fenced, lined area. The tanks are currently in use supplying the nearby house, the Hut (Boys and Girls Club). | Grant Lidren |
| 10/13/2009 | Document, Report, or Work plan Review - other | ADEC approved the Akiak Combined TF Site Characterization Work Plan Akiak Alaska submitted by SLR. Site work is scheduled for the week of October 26, 2009. | Grant Lidren |
| 2/18/2010 | Document, Report, or Work plan Review - other | ADEC reviewed Old Elementary School Tank Farm Site Characterization Report, dated February 8, 2010, submitted by SLR. Eighteen soil samples were collected from six test pits and two soil borings located around the tank farm. Test pits were not advanced south or northwest of the tank farm due to obstructions. Soil samples from test pit 2 and soil boring 1, located west of the tank farm, collected at a depth of 2.5 to 8.0 ft. bgs, contained GRO up to 2,640 mg/kg, DRO up to 22,300 mg/kg, benzene up to 0.0638 mg/kg, toluene up to 8.54 mg/kg, total xylenes up to 89.4 mg/kg and PAHs 1-methylnapthalene and 1-methylnapthalene up to 82.3 mg/kg and 100 mg/kg respectfully. An estimated 285 cubic yards of petroleum impacted soil is located at this location. The rest of the test pits contained detectable levels of contaminants, but below cleanup levels (note: the PQLs for some of the VOC samples were elevated due to matrix interference, therefore these samples could be over cleanup levels). Groundwater was not encountered at 14 ft. bgs, consequently drive point wells were not installed. The closest drinking water well is located 500 ft away from the tank farm. | Grant Lidren |
| 3/13/2012 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 74342 ASTs. | Grant Lidren |
