(3) The BCMOE and APHA Standard Method require ph to be analysed within 5 minutes of sampling and therefore field analysis is required for compliance. All Laboratory ph analyses in this report are reported past the BCMOE/APHA Standard Method holding time. (4) TOC present in the sample should be considered as nonpurgeable TOC. Page of 3

Used to evaluate the variance in the measurement. Recovery : A sample to which a known amount of the analyte of interest has been added. Used to evaluate sample matrix interference. : A blank matrix sample to which a known amount of the analyte, usually from a second source, has been added. Used to evaluate method accuracy. : A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination. (Duplicate ): The duplicate was not calculated. The concentration in the sample and/or duplicate was too low to permit a reliable calculation (absolute difference <= 2x RDL). UNITS QC Limits (): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration) Page of 3
