Mr. Scott Hilyard - 3 - 27 July 2007 <br /> how CA ARNG would select soil samples for analysis in borings that do not encounter <br /> suspected contamination. <br /> 4. Page 9, Section 6.6: The last sentence in this section is unclear and appears to refer to <br /> sampling methods that are not discussed. Revise this sentence to identify which <br /> sampling methods will be used if the HydroPunch technique is unsuccessful. <br /> 5. Page 9, Section 6.7: This section states that "a trip blank, temperature blank, and <br /> equipment blank may also be added to the list of QA/QC samples submitted for analysis; <br /> if applicable during the field investigation." Please explain why these samples would not <br /> be applicable or revise the Work Plan to state these samples will be collected. <br /> If you have any questions, please contact me at (916) 464-4733 <br /> (m pierce(aD-waterboards.ca.coy). <br /> C/ <br /> Marcus L. Pierce, C.Hg. <br /> Engineering Geologist <br /> cc: <br /> Ms. Margaret Lagorio, San Joaquin County Environmental Health Department, Stockton <br /> Ms. Devra Lewis, California Army National Guard <br /> Mr. Vern Elarth, URS, Sacramento <br />
