Monitoring for microbiological control is crucial for effective #watertreatment programs. Traditional methods often overlook bacteria within biofilms, which can make up to 90% of microbial activity in a system.

The microbial population in a water sample can change over time, which can lead to inaccurate assessments of water quality. Therefore, it is recommended that water samples be transported and analyzed within six hours. It is dependent on your validation research of a storage water sample at 2-8°C. Samples should be collected for microbiological examination in sterile containers. Samples should be kept in a refrigerator 2-8°C. The sample should be analyzed within two hours of collection, if not, store it between 2-8 degrees Celsius. Before analysis water sample attain room temperature. If a sample exceeds the holding time, it is considered suspect, and the sample collection may have to be repeated. Some microbes may survive for a month in storage in water, but others may not. For example, if the pH of a water sample collected in the field is 6.8, it may rise to 7.5 by the time the sample arrives for analysis in a laboratory. This is because dissolved CO2 leaves the sample once it's warmed, which affects the equilibrium of carbonic acid.

The Most Probable Number (MPN) tube technique is a microbiological method involving serial dilution and inoculation of a sample into liquid growth medium tubes. After incubation, positive tubes indicating microbial growth are counted, and statistical tables or software are used to estimate the Most Probable Number, providing a concentration estimate of viable microorganisms in the original sample. This technique is valuable in scenarios with low microbial concentrations, such as water and food testing
