ROY F. WESTON, INC. <br />n9DU STOCKTON ANALYTICAL LABORATORY <br />INORGANICS CASE NARRATIVE <br />Client: CAL CEDAR <br />RFW #: 89035075 <br />W.O. #: 5448-01-01-0000 <br />MAY 24 1489 <br />ENVP(-;1`,1V1EN 1Al hlEALIH <br />PERMIT / SERVIC-ES <br />1. All required holding times were met. <br />2. All method blanks were analyzed below detection limits. <br />3. All LCS (blank spike) recoveries were within control limits. <br />4. As per request, these samples were reanalyzed for CAM metals <br />as opposed to EPTOX metals. This reanalysis was performed on <br />05/11/89, well within holding time constraints. <br />5. The following data qualifiers are used in the enclosed <br />report: <br />U - Indicates that the sample was analyzed for but not <br />detected. <br />* - Indicates that the original sample result was <br />greater than 4 x the spike amount added. The USEPA- <br />CLP has determined that spike sample calculations <br />where this occurs have been proven to be unreliable. <br />6. Methodology unless otherwise indicated follows the USEPA-CLP <br />SOW -787 for metals analysis; Methods for Chemical Analysis of <br />Water and Wastes for conventional water analyses; and SW -846 <br />for nonmetallic soil parameters. <br />0 <br />1d46-/ <br />Date: �� (1U Approved: • U- <br />L , \E .
