NCDEQ-WSS-Chemistry Lab Data Qualifiers Al The reported value is an average, where at least one result is qualified with a "U". The PQL is used for the qualified result(S) to call B1 Coliform-Countable membranes with less than 20 colonies. Reported value is estimated or is a total of the counts on all filters repor B2 Coliform-Counts from all filters were zero. B3 Coliform-Countable membranes with more than 60 or 80 colonies. The value reported is calculated using the count from the smalle B4 Coliform-Filters have counts of both >60 or 80 and <20. Reported value is estimated or is a total of the counts on all filters reported B5 Coliform-Too many colonies were present; too numerous to count (TNTC). TNTC is generally defined as >150 colonies. B6 Col iform-Esti mated Value. Blank contamination evident. B7 Coliform-Many non-coliform or non-enterococcus colonies or interfering non-coliform or non-enterococcus growth present. In this cc BB1 MPN-No wells or tubes gave a positive reaction. Value based upon the appropriate MPN Index and reported as a less than "<" valu BB2 MPN-All wells or tubes gave positive reactions. Value based upon the MPN Index and reported as a greater than ">" value. C Total residual chlorine was present in sample upon receipt in the laboratory; value is estimated. G1 BOD-The dissolved oxygen (DO) depletion of the dilution water blank exceeded 0.2 mg/L. G2 BOD-The bacterial seed controls did not meet the requirement of a DO depletion of at least 2.0 mg/L and/or a DO residual of at lea: G3 BOD-No sample dilution met the requirement of a DO depletion of at least 2.0 mg/L and/or a DO residual of at least 1.0 mg/L. G4 BOD-Evidence of toxicity. This is generally characterized by a significant increase in the BOD value as the sample concentration de G5 BOD-The glucose/ glutamic acid standard exceeded the range of 198 ± 30.5 mg/L. G7 BOD-Less than 1 mg/L DO remained for all dilutions set. The reported value is an estimated greater than value and is calculated foi G8 BOD-Oxygen usage is less than 2 mg/L for all dilutions set. The reported value is an estimated less than value and is calculated for G9 BOD-The DO depletion of the dilution water blank produced a negative value. J1 Surrogate recovery limits have been exceeded. J10 Unidentified peak; estimated value.

The estimated concentration J12 The calibration verification did not meet the calibration acceptance criterion for field parameters. J2 The reported value failed to meet the established quality control criteria for either precision or accuracy. J3 The sample matrix interfered with the ability to make any accurate determination. J4 The data is questionable because of improper laboratory or field protocols (e.g., composite sample was collected instead of grab, p J5 Temperature limits exceeded (samples frozen or >6°C) during transport or not verifiable (e.g., no temperature blank provided): non- J6 The laboratory analysis was from an unpreserved or improperly chemically preserved sample. The data may not be accurate. J7 This qualifier is used to identify analyte concentration exceeding the upper calibration range of the analytical instrument/method. Th J8 Temperature limits exceeded (samples frozen or >6°C) during storage, the data may not be accurate. J9 The reported value is determined by a one -point estimation rather than against a regression equation. The estimated concentration M Sample and duplicate results are 'but of control". The sample is non -homogenous (e.g., VOA soil). The reported value is the lower, N1 Presumptive evidence and estimated value. The component has been tentatively identified base on mass spectral library. N2 There is an indication that the analyte is present, but quality control requirements for confirmation were not met (i.e., presence of N3 This code shall be used if the level is too low to permit accurate quantification, but the estimated concentration is less than the labo N4 This code shall be used if the level is too low to permit accurate quantification, but the estimated concentration is less than the labo N5 The component has been tentatively identified based on a retention time standard. P Elevated PQL* due to matrix interference and/or sample dilution. Q1 Holding time exceeded prior to receipt by lab. Q2 Holding time exceeded following receipt by lab. S Not enough sample provided to prepare and/or analyze a method -required matrix spike (MS) and/or matrix spike duplicate (MSD). U Indicates that the analyte was analyzed for but not detected above the reported practical quantitation limit*. The number value repo U, J6 The laboratory analysis was from an unpreserved or improperly chemically preserved sample. The data may not be accurate. UU Indicates that the analyte was not detected by a screen analysis. The number value was determined by a one -point estimation at tf V Indicates the analyte was detected in both the sample and the associated method blank. Note: The value in the blank shall not be s X1 Sample not screened for this compound. X2 Sampled, but analysis lost or not performed -field error. X3 Sampled, but analysis lost or not performed -lab error. Y Elevated PQL* due to insufficient sample size. Z1 Inability to analyze the sample. Z2 Questions concerning data reliability.
