Vogue Cleaners 1 Norman Higgins page 2 <br /> 2315 N. California St., Stockton. <br /> Please advise your consultant to have the laboratory list all soil data listed in <br /> "mglkg" only and all groundwater data in "Lig/1" only. Your consultant can <br /> inform the laboratory in the "notes" section on 1he Chain of Custody. <br /> Included in your consultant's report was an ex lavation for using EPA Method <br /> 8240 instead of EPA Method 8260 for the oxy enates. PHS-EHD will allow this <br /> one time use of 8240 to meet the requirements for testing the oxygenates. <br /> Please be advised that future testing of the oxygenates (post-remedial <br /> confirmation sampling) will require the use of EPA Method 8260. Although no <br /> additional oxygenate groundwater sample analyses is required at this time for <br /> the existing monitoring wells at your site, PHS- HD recommends that you <br /> discuss with your consultant the need to verify the oxygenate presence in the <br /> groundwater at your site with method 8260 for all seven constituents before <br /> entering the remediation phase. The presence of oxygenates in soil or <br /> groundwater from confirmation sampling after 1he completion of remediation <br /> could result in difficulties in obtaining the "No Further Action" certification. <br /> Please have your consultant modify some oft the reporting format. All site maps <br /> are to orient the site with "north" at the top oft the page. TPH-G, TPH-D, and <br /> TPH-SS are present at this site and tables of groundwater and soil results are to <br /> list these constituents separately. Tables that ist "ND" only should have the <br /> detection limit unit (i.e., 0.5 ug/l) listed on the t ble either next to the result or in <br /> the legend. Laboratory identification numbers are not needed in tables. <br /> Please contact Michael Infurna at (209) 468-34-54 if you have any questions or <br /> wish to discuss the site. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> ,,,�C,�L� /-5� —fyl-,�ATn:� <br /> Michael J.
