Verifies the precision of the instrument and /or method Determines sample matnx interferences, if any Verifies the validity of the calibration ACZ Qualifiers (Qual) Analyte concentration detected at a value between MDL and PQL The associated value is an estimated quantity. Analysis exceeded method hold time. pH is a field test with an immediate hold time Target analyte response was below the laboratory defined negative threshold The matenal was analyzed for, but was not detected above the level of the associated value The associated value is either the sample quantitation limit or the sample detection limit EPA 600/4 -83 -020 Methods for Chemical Analysis of Water and Wastes, March 1983 EPA 600/R -93 -100. Methods for the Determination of Inorganic Substances in Environmental Samples, August 1993 EPA 600 /R- 94-111 Methods for the Determination of Metals in Environmental Samples - Supplement I, May 1994 EPA SW -846 Test Methods for Evaluating Solid Waste Standard Methods for the Examination of Water and Wastewater QC results calculated from raw data Results may vary slightly if the rounded values are used in the calculations Soil, Sludge, and Plant matrices for Inorganic analyses are reported on a dry weight basis. Animal matrices for Inorganic analyses are reported on an "as received" basis An asterisk in the "XQ" column indicates there is an extended qualifier and /or certification qualifier associated with the result 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* http acz com/public /extqualltst pdf Page 11 of 38
