21 March 2011 <br />AGE-NC Project No. 10-1810 <br />Page 3 of 5 <br />sample containers were labeled with soil boring designation, date, time, and samplers <br />initials and then placed in a chilled container. <br />Following soil and grab ground water sample collection, probe-boring locations were <br />backfilled to surface grade with Portland cement. Grouting of the borings was witnessed <br />by representatives of the SJCEHD. <br />SAMPLE ANALYSES <br />Soil and grab ground water samples were transported under chain-of-custody to Cal Tech <br />Environmental Laboratories (CTEL), a California Department of Health Services-certified <br />laboratory, and analyzed for the following: <br />Carbon chain in accordance with EPA Method 8015M; and <br />Volatile organic compounds (VOCs) in accordance with EPA Method 8260B. <br />EQUIPMENT DECONTAMINATION <br />Prior to sample collection soil sampling equipment was thoroughly rinsed with clean water <br />after being washed with a solution of Alconox. Push rods were thoroughly cleaned prior to <br />soil probe boring advancement. <br />FINDINGS <br />Utilizing the OVM, organic vapors were not detected in any of the soil samples. Analytical <br />results of soil and grab ground water samples are summarized in the table below. <br />PHASE II ANALYTICAL RESULTS <br />Sample <br />ID Matrix Date GRO DRO MRO VOCs <br />concentrations in micrograms per liter (pg/l) <br />B2-W grab gw 01/13/11 ND ND ND 1,1-DCE: 4.8 .6•0 <br />vk - 0 <br />1,1-DCE: 650-- ,y <br />- <br />0 0 ,0Th <br />1,1-DCA. 51-- B3-W grab gw 01/13/11 900 ND ND 1,2-DCE: 3.7-' <br />ICE: 32,4 <br />Advanced GeoEnvironmental, Inc.
