Coliform Count

A test of water potability
Untreated water, e.g., from the Thames:
Typical coliform count ± 2,000 bacteria/100 cm3
Mechanically treated water—Post storage, sedimentation and clarification: ± 10 bacteria/100 cm3
Chemically treated water—disinfection with chlorine or ozone: 0 bacteria/100 cm3 for safely distribution to public

Similarly, these hotels were found to have released wastewater into Coron Bay, contributing to the presence of high coliform count in some portions of it.
The coliform count in a sampling station in Davao River amounted to 16-million MPN (most probable number) per 100 liters compared to the standard of standard of 200 MPN per 100 liters.

Microbial Analysis: In the laboratory, water samples were processed for analysis of total viable, coliform and fecal coliform count. Total viable count (TVC) in the water samples were performed by spread plate method using Nutrient agar medium(Suthar et al.
The samples were subjected for total bacterial count (TBC), total coliform count (TCC) and isolation.
Aliquots of each dilution were spreaded on Nutrient agar (Himedia Labs, Mumbai, India) for aerobic plate count (APC) and MacConkey agar (Himedia Labs, Mumbai, India) for total coliform count (TCC) as described by Lateef and Kana (2014).
