Koli-Index

The coli index is an indicator that is used to assess water quality. It is determined by counting the number of E. coli in 100 ml of water. Escherichia coli is one of the most common microorganisms in nature and can cause various diseases in humans.

The coli index is an important indicator for assessing the safety of drinking water, as high levels of E. coli can lead to gastrointestinal diseases and other health problems. Therefore, monitoring the quality of drinking water is an important task for government agencies and organizations involved in water supply.

To determine the number of E. coli, the method of inoculating water on a special nutrient medium is used. After incubation for a certain time, bacterial colonies grow and can be counted. The number of colonies, expressed in quantity per 1 ml of water, is the coli index.

Depending on the coli index value, water can be classified into several categories:

1. Water with high levels of E. coli (more than 10). Such water cannot be used for drinking without additional treatment.
2. Water with moderate levels of coliforms (3 to 10). This water can be used for drinking, but requires additional purification or filtration.
3. Water with low coliform levels (less than 3). This water is considered safe to drink and does not require additional purification measures.

The quality of drinking water is controlled through regular inspections and monitoring. This allows you to identify water quality problems and take corrective action.

Thus, the coli index is an important indicator of drinking water quality and helps protect public health. Regular monitoring and control of water quality are necessary measures to ensure the safety of the population.

The coli index is a microbiological indicator that is used to assess the bacterial contamination of water. It measures the amount of E. coli (Escherichia coli) in one milliliter of water and is used to determine the quality of drinking water.

Escherichia coli is one of the most common microbes in nature, usually found in the intestines of animals and humans. Most types of E. coli do not pose a risk to human or animal health, but some
