ADZ Laboratories, Inc. 2773 Downhill Dnve Steamboat Spnngs,CO 80487 (800)334-5493 Report Header Explanations Batch A distinct set of samples analyzed at a specific time Found Value of the QC Type of interest Limit Upper limit for RPD,in%. Lower Lower Recovery Limit,in% (except for LCSS,mg/Kg) MDL Method Detection Limit Same as Minimum Reporting Limit unless omitted or equal to the PQL(see comment#5) Allows for instrument and annual fluctuations. PCN/SCN A number assigned to reagents/standards to trace to the manufacturers certificate of analysis PQL Practical Quantitation Limit. Synonymous with the EPA term"minimum level". QC True Value of the Control Sample or the amount added to the Spike Rec Recovered amount of the true value or spike added,in%(except for LCSS,mg/Kg) RPD Relative Percent Difference,calculation used for Duplicate QC Types Upper Upper Recovery Limit,in% (except for LCSS,mg/Kg) Sample Value of the Sample of interest OC Sample Types AS Analytical Spike(Post Digestion) LCSWD Laboratory Control Sample-Water Duplicate ASD Analytical Spike(Post Digestion)Duplicate LFB Laboratory Fortified Blank CCB Continuing Calibration Blank LFM Laboratory Fortified Matra CCV Continuing Calibration Verification standard LFMD Laboratory Fortified Matra Duplicate DUP Sample Duplicate LRB Laboratory Reagent Blank ICB Initial Calibration Blank MS Matrix Spike ICV Initial Calibration Verification standard MSD Matrix Spike Duplicate ICSAB Inter-element Correction Standard-AplusBsolutions PBS Prep Blank-Soil LCSS Laboratory Control Sample-Soil PB W Prep Blank-Water LCSSD Laboratory Control Sample-Soil Duplicate PQV Practical Quantitation Venficetion standard LCSW Laboratory Control Sample-Water SDL Serial Dilution QC Sample Type Explanations Blanks Verifies that there is no or minimal contamination in the prep method or calibration procedure. Control Samples Verifies the accuracy of the method,including the prep procedure. Duplicates Verifies the precision of the instrument and/or method Spikes/Fortified Matra Determines sample matrix interferences,if any. Standard Verifies the validity of the calibration. ACZ Qualifiers • . B Analyte concentration detected at a value between MDL and PQL The associated value is an estimated quantity. H Analysis exceeded method hold time. pH is a field test with an immediate hold time. L Target analyte response was below the laboratory defined negative threshold U The material was analyzed for,but was not detected above the level of the associated value The associated value is either the sample quantitaton limit or the sample detection limit Method References (1) EPA 600/4-83-020.

Results may vary slightly it the rounded values are used in the calculations (2) Soil,Sludge,and Plant matrices for Inorganic analyses are reported on a dry weight basis (3) Animal matrices for Inorganic analyses are reported on an"as received"basis. (4) An asterisk in the"XQ"column indicates there is an extended qualifier and/or certification qualifier associated with the result. (5) If the MDL equals the PQL or the MDL column is omitted,the PQL is the reporting limit For a complete list of ACZ's Extended Qualifiers,please click: https:Hacz.coin/wp-content/u ploads/2019/04/Ex t-Oua I-Li st.pdf REP001 03 15.02 L70424-2201310853 Page 4 of 23
