2. Bacteriological water analysis - Wikipedia

   en.wikipedia.org/wiki/Bacteriological_water_analysis

   Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...

3. Winogradsky column - Wikipedia

   en.wikipedia.org/wiki/Winogradsky_column

   This is followed by water from the pond to saturate the mud (or sand) and occupy half the remaining volume. The column is sealed tightly to prevent evaporation of water and incubated for several months in strong natural light. After the column is sealed tightly the anaerobic bacteria will develop first, including Clostridium spp. These ...

7. Dip slide - Wikipedia

   en.wikipedia.org/wiki/Dip_slide

   For some water systems a weekly dip slide test is recommended. For multiple tests the incubation period and temperature should be the same each time a new sample is assessed. Bacteria present in the sample liquid will grow and form colonies. A bacterial reference chart is used to determine the number of bacteria in the sample. Appropriate ...
