' BMG Resources ~ Terracon
' Soil Sampling at the Historic Fueling Area
Project No. 46027059
October 22, 2002
Although the fill material below four inches appeared moist, free water was not observed at
any depth in the excavation. Terracon observed a light gray discoloration in the 4-inch to
12-inch bgs layer of soil. Terracon did not observe obvious discoloration in the lower
' material. With the exception of urine odor likely associated with livestock activity, Terracon
did not note unusual odors in any of the soil removed from Excavation No. 1.
3.2.2 Northern Test Excavation No. 2 Observations
Test Excavation No. 2 observations were recorded during August 29 field activities. Test
Excavation No. 2 was located approximately six feet to the north of the northern electrical
connection. Terracon encountered fill material at all depths. Fill material consisted of a clay
and gravel mixture in the upper 12 inches followed by a sandy fill material to at least six
inches below the liner (located at approximately 30 inches bgs). Although the fill material
below four inches appeared moist, free water was not observed at any depth in the
excavation. Terracon did not observe obvious discoloration associated with any material
observed in the second excavation. With the exception of urine odor lilley associated with
livestock activity, Terracon did not note unusual odors in any of the soil removed from
Excavation No. 2.
4.0 LABORATORY ANALYSES
4.1 Soil Samples
As described in Section 3.0, a total of six soil samples were collected for laboratory
analysis. The samples were containerized in laboratory-prepared bottles that were labeled
identifying the sample name, coltectiori time and date, and the laboratory analyses. The
samples were placed in an ice-filled cooler and hand delivered under standard Terracon
chain-of custody procedures to Evergreen Analytical Laboratory in Wheat Ridge, Colorado.
The laboratory was requested to analyze the soil samples for benzene, toluene,
ethytbenzene, and xylenes (BTEX by EPA Method 8020) and total recoverable petroleum
hydrocarbons (TRPH by EPA Method 418.1).
4.2 Sample Analytical Results
Table 4.2-1 which follows, summarizes the sample analytical results. The laboratory
sample analytical report is presented in Appendix D.
