Cecchuu, Cecchuu and G ovannau, Fueling Island 1.2 Work Peirffoirmed Second Quainter 096 The following tasks were performed during the Second Quarter of 1996 at the fuel island area o Installation of monitoring well UST-5 and vapor well VP-1, and o Ground water monitoring and sampling 2.0 RnstaRzfloun off New Monftorkg Wi eRN To further monitor hydrocarbons in ground water beneath the fuel island, ESE proposed in a workplan dated April 17, 1996, installation of a ground water monitoring well UST- 5 and soil vapor well VP-1 An addendum to the workplan dated May 6, 1996 was prepared to document changes in the well design to a nested configuration per Mr Michael Infurna of the SJCEHD The permit for monitoring well installation approved on May 31, 1996 2.1 ]ExpRoratoiry IIDirflUng aAs described in the work plan, a mobile drill rig equipped with 12-inch hollow-stem auger was used to make the exploratory borehole. Mork commenced on June 13, 1996 and was completed that day Soil samples were collected at five foot intervals using a modified split-spoon sampler Soils were described using the Unified Soil Classification System (ASTM 2488-84). The exploratory boring UST-5 was located on the east side of the fuel island between UST-1 and the gasoline underground storage tank (UST) were ea labeled and laced in an ice Soil samples selected for laboratory analyses e e pped, p chest under chain-of=custody for transport to a California Certified Laboratory. Soils were tested for Total Petroleum Hydrocarbons as Diesel (TPH-D) using EPA method 3553/8015 modified, for Total Petroleum Hydrocarbons as Gasoline (TPH-G) using EPA method 503018015, and for benzene, ethylbenzene, toluene, and xylenes (BTEX) using EPA method 5030/8020 The findings of these tests are presented in Section 4 2 of this report !+ Envnronwntal Science&Engineering, Inc 1692540012QM96 RPT 2
