r <br /> } <br /> SECOR calculated the initial mass removal rates for each well using the average flow rate observed during <br /> testing and the analytical results of vapor samples collected near the end of each test Vacuum and flow rate <br /> information is summarized on Table 1 through Table 8 in the attached report Analytical results are <br /> summarized in Table 9 of the attached report and laboratory reports are included as Attachment A Initial <br /> mass removal calculations are included as attachment B <br /> Based on the results of the pilot test, it appears as though vapor extraction will be a feasible technology for <br /> addressing hydrocarbon-impacted sods at the subject site Figure 2 in the attached report illustrates that the <br /> majority of impacted sods can be influenced by vapor extraction from W-1 through W-8 with an assumed 50- <br /> foot radius of influence <br /> If you have any questions regarding these matters, please do not hesitate to contact me at(206) 286-4495 <br /> Sincerely, <br /> Time Oil Co <br /> A-4&04 C-�� —wkr�� <br /> Anastasia E Duarte-Wilkinson <br /> Environmental Toxicologist <br /> cc Ms Elizabeth Thayer <br /> California Regional Water Quality Control Board <br /> • may9844049I35 doe <br /> 2 <br />
