The holding time for <br />Oxygen,Dissolved, pH are listed as immediate. Logistically this is very difficult to obtain. FGL policy is <br />to analyze all samples requiring Oxygen,Dissolved, pH on the same day of receipt at the laboratory. If <br />this presents any problem please call. <br />All samples arrived on ice. All samples were checked for pH if acid or base preservation is required <br />(except for VOAs). For details of sample receipt information, please see the attached Chain of Custody <br />and Condition Upon Receipt Form. <br />Quality Control: All samples were prepared and analyzed according to the following tables: <br />Enorganic - Metals QC <br />200.7 04/04/2013:204847 All analysis quality controls are within established criteria. <br />04/04/2013:203632 All preparation quality controls are within established criteria, except: <br />3010 The following note applies to Calcium, Magnesium: <br />430 Post Digestion Spike (PDS) not within Acceptance Range (AR) because of matrix interferences <br />affecting this analyte. <br />Page 1 of 21 <br />Corporate Offices & Laboratory <br />Office 8 Laboratory <br />Required Holding <br />Actual holding <br />Lab ID <br />AnaIyte/Method <br />2500 Stagecoach Road <br />563 E.
