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. The value reported is based on the number of colonies per 100 ml that would have been
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.

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.
G6 BOD-The calculated seed correction exceeded the range of 0.6 to 1.0 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
