A total of 529 well and distribution potable water samples were analyzed for total coliforms by the most probable number (MPN) and membrane filter (MF) techniques. Standard plate count (SPC) bacteria and MF non-coliform bacteria were also enumerated. Frequency of coliform detection, turbidity in MPN tubes and extensive overgrowth by non-coliforms on MF filters were directly proportional to SPC. Overgrowth by non-coliforms on MF filters suppressed sheen development and, in turn, masked coliform detection.
