Sample Comments
NCDEQ-WSS-Chemistry Lab Data Qualifiers
A1 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 calculate the average.
B1 Coliform-Countable membranes with less than 20 colonies. Reported value is estimated or is a total of the counts on all filters reported per 100 ml.
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 smallest volume filtered and reported as a greater than ">" value.
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 per 100 ml.
B5 Coliform-Too many colonies were present; too numerous to count (TNTC). TNTC is generally defined as >150 colonies.
B6 Coliform-Estimated Value. Blank contamination evident.
B7 Coliform-Many non-coliform or non-enterococcus colonies or interfering non-coliform or non-enterococcus growth present. In this competitive situation, the reported value may under-represent actual density.
BB1 MPN-No wells or tubes gave a positive reaction. Value based upon the appropriate MPN Index and reported as a less than “<” value.
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 least 1.0 mg/L.
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 decreases. The reported value is calculated from the highest dilution representing the maximum loading potential and
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 for the dilution using the least amount of sample.
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 the dilution using the most amount of sample.
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.

J11 The reported value is determined by a one-point estimation rather than against a regression equation. The estimated concentration is less than the laboratory practical quantitation limit and greater than the instrument noise level. This code is used when
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, plastic instead of glass container, the sample's extraction batch did not include a LCS/MS/MSD, etc.).
J5 Temperature limits exceeded (samples frozen or >6°C) during transport or not verifiable (e.g., no temperature blank provided): non-reportable for NPDES compliance monitoring.
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. The reported value should be considered estimated.
J8 Temperature limits exceeded (samples frozen or >6ºC) 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 is less than the laboratory practical quantitation limit and greater than the laboratory method detection limit.
M Sample and duplicate results are "out of control". The sample is non-homogenous (e.g., VOA soil). The reported value is the lower value of duplicate analyses of a sample.

N2 There is an indication that the analyte is present, but quality control requirements for confirmation were not met (i.e., presence of analyte was not confirmed by alternate procedures).

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 reported with the "U" qualifier is equal to the laboratory's practical quantitation limit*.
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 the PQL.
V Indicates the analyte was detected in both the sample and the associated method blank. Note: The value in the blank shall not be subtracted from the associated samples.
