7 The following section reports quality control (QC) data that is associated with your sample data. Groups of samples are prepared in batches and analyzed in conjunction with quality control samples that ensure your data is of the highest quality. Common QC types include: Method Blank (Blk): Laboratory reagent water is carried through sample preparation and analysis steps. Method Blanks indicate that results are free from contamination, i.e. not biased high from sources such as the sample container or the laboratory environment Duplicate (Dup): Preparation and analysis of a replicate aliquot of a sample. Duplicates provide a measure of the analytical method s precision, i.e. how reproducible a result is. Duplicates are only reported if they are associated with your sample data. Blank (BS): A known amount of standard is carried through sample preparation and analysis steps. Blank s, also known as laboratory control samples (LCS), are prepared from a different source of standard than used for the calibration. They ensure that the calibration is acceptable (i.e. not biased high or low) and also provide a measure of the analytical method s accuracy (i.e. closeness of the result to a target value). Standard Reference Material (SRM): A material of similar matrix to the samples, externally certified for the parameter(s) listed. Standard Reference Materials ensure that the preparation steps in the method are adequate to achieve acceptable recoveries of the parameter(s) tested for. Each QC type is analyzed at a -10% frequency, i.e. one blank/duplicate/spike for every 10 samples. For all types of QC, the specified recovery (% Rec) and relative percent difference () limits are derived from long-term method performance averages and/or prescribed by the reference method. s Aggregate Organic Parameters, Batch R Blank (R BLK1) Prepared: Feb Analyzed: Feb EPHw (10-19) EPHw (19-32) LCS (R BS1) EPHw (10-19) 370 EPHw (19-32) 4420 Prepared: Feb Analyzed: Feb Aggregate Organic Parameters, Batch R Blank (R BLK1) VHw (6-10) LCS (R BS2) VHw (6-10) General Parameters, Batch K90037 Blank (K90037-BLK1) Prepared: Feb Analyzed: Feb Conductivity (EC) us/cm Blank (K90037-BLK2) Prepared: Feb Analyzed: Feb Conductivity (EC) us/cm LCS (K90037-BS1) Prepared: Feb Analyzed: Feb Conductivity (EC) 1390 us/cm LCS (K90037-BS2) Prepared: Feb Analyzed: Feb Conductivity (EC) 1400 us/cm General Parameters, Batch K Blank (K BLK1) Prepared & Analyzed: Feb-0-09 Nitrogen, Ammonia as N 0.02 Blank (K BLK2) Prepared & Analyzed: Feb-0-09 Nitrogen, Ammonia as N 0.02 Page 7 of 13
