The Direct Push Technology (DPT)provides discrete depth soil sampling <br /> without generating investigation derived waste. The DPT methodology is the-only change <br /> to the Site. Contamination Work Plan. The location and depth of the-borings have not <br /> changed. The depth of the borings will extend up to SO feet below ground surface. Up to <br /> five soil samples will be selected.from each-boring for chemical analysis. The-soil samples <br /> ` will be analyzed for Total Petroleum Hydrocarbons (TPH) as diesel and TPH as gasoline <br /> using:modified .EPA Method 8015, and benzene, toluene, ethylbenzene, and total xylenes <br /> rt using EPAMethod8020. .The.chemical analysis of soil samples will be conducted by a State <br /> of.California certified analytical laboratory. <br /> If you have any questions, please callme.at(916) 368-0988 or Mike Sartor.in our Oakland <br /> office at (510) 874-3173. <br /> Very truly yours, <br /> WOODWARD-CLYDE <br /> William Loskutoff <br /> Geologist <br /> i cc: Alan Graft (KJAX) Harry Butler (WCFS Rockville, MD)- <br /> Mike Sartor(WCFS Oakland; CA) Don Siligo (EN PROBE) <br /> Chuck Georgius (WCFS Gaithersburg, MD) <br /> j Attachments: Figure 3 - Site Map with Proposed Soil Boring Locations <br /> 8054WAXPERM.LTR (03.15.95).SAC. - - <br />
