The samples from each <br /> well will be collected in two pre-cooled and cleaned 46-m1 VOA vials and a 1- <br /> F;a. liter amber glass bottle. The VOA vials will be preserved with Sodium azide or <br /> es of organic contaminant, <br /> sodium hydrogen sulfate and will be used for analys <br /> TPH, BTEX, EDC, and EDB by EPA method 524.2. The 1-liter amber glass bottles <br /> will be preserved with nitric acid and will be used for analyses for total lead <br /> by EPA method 7420• the containers will be <br /> a Immediately following sample collection, <br /> head space, labeled, sealed with electrical tape, secured in <br /> sealed, without <br /> F1 containing artificial ice <br /> guard bottles VOA vials), and placed in an ice chest <br /> ation documentation will <br /> for preservation. Chain-of-custody/sample presery <br /> round water samples from collection to the laboratory. <br /> We plan <br /> accompany the g P <br /> to use Coast to Coast Analytical Services, Goleta to conduct the laboratory <br /> analyses for both the ground water samples and the soil samples. <br /> Fes, <br /> REPORT PREPARATION <br /> We will prepare and submit a technical report summarizing the <br /> results of our findings and presenting recommendations for additional site <br /> remediation if necessary. <br /> WORK PLAN <br /> SGD is prepared to implement this technical work plan within two <br /> . Initial soil sampling will require one <br /> weeks of receipt of approval by 5JLHD <br /> day, field work will be completed within two to three days. Laboratory analysis <br /> be submitted <br /> will require two to three weeks to complete.
