Y a is k 3 The soil samples were collected, labelled, and handled in a manner identical to the procedure described in Section 2.1. The product lines were located at a depth of approximately two feet bgs and appeared to be encased in concrete. No concrete casing existed around the product pipes along Fuel Island No. 2 (see Figure 3) . 2.3 SAMPLING E UIPMENT CI,F.ANTNG RROTOCOL All soil sampling equipment was decontaminated between each sampling by the following procedure: - All excess soil was scraped off the sampler parts; - The sampler was washed in a solution of Alconox detergent and tap water; and - The sampler was rinsed with tap water and then distilled water. 2 .4 EFFLUENT HANDLING All effluent generated during assessment activities were sealed in labeled 55-gallon drums. The drums were stored on- site, pending the results of the analytical testing, at which time the appropriatE disposal method was determined. 3.0 SUBSURFACE CONDITIONS The subsurface conditions encountered in the soil borings are presented on the boring logs (see Appendix B) . The following is a generalized summary of the soil stratigraphy encountered. The two soil borings around the sewer line (SB-1 and SB-2) encountered man-made fill to a maximum depth of approximately 3.5 feet bgs. Both man-made fill and natural ground to the termination depth of the borings consisted of a brown and moist, slightly sandy silt. The soil stratigraphy at the proximity of the product lines, below the concrete pavement and gravel base consisted of a thin layer of man-made fill to a maximum depth of approximately 1.5 E - feet bgs. The fill consisted of a brown sandy to slightly sandy silt sandwiched between two layers of sandy gravel. Below this fill, natural ground consisting of a thin layer of dark brown to black organic silty clay (one to two fee'-- thick) was encountered and interbedded with thin layers of tan to brown slightly sandy to slightly clayey silt to the termination depth of the borings. 3 � J Project No. 1232 -4- E ENVIPOWMENTAL AUDIT,INC s.a ..
