... of 16 mg/L while outflow P was <0.2 mg/L until 25 d. Thereafter, P outflow concentrations increased and had a mean value of 10 mg/L. Fecal coliform removal averaged 99.97% during the first 51 d. The stratified sand filter may provide an alternative wastewater disposal system for many locations...

... Potable water specimens, usually well water, were analyzed for total and fecal coliforms by a Standard Methods membrane filtration test (MF) and the Colilert Presence/Absence test (CPA), Access Analytical, Inc., Branford, CT. MF sample membrane filters were incubated on M-Endo agar plates at 35...

... This study was designed to demonstrate the magnitude of the bias of the most probable number (MPN) test when applied to sediment. Sterile sediment samples were inoculated with fecal coliforms or Pseudomonas aeruginosa organisms, and recovery by MPN and plate count procedures was compared...

... quality. KEY WORDS: bacteria, water, fecal coliforms Drinking water of good bacteriological quality in the United States is indicated by the absence of coliforms when a minimum of 100 ml is tested by the membrane filter (MF) technique or 50 ml by the most probable number (MPN) method. Due to limitations...
