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.
