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.
