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
