What is BS EN ISO 9308-8:2019?

BS EN ISO 9308-8:2019 is a professional technical standard that focuses on the enumeration of Escherichia coli

(E. coli) and coliform bacteria. It provides guidelines for the measurement of these bacteria in different water

samples, such as drinking water, ground water, surface water, and more. This standard plays a crucial role in

ensuring the safety and quality of water resources.

The importance of BS EN ISO 9308-8:2019

BS EN ISO 9308-8:2019 is essential for several reasons. Firstly, it helps to detect and monitor the presence of

potentially harmful bacteria in water sources. E. coli and coliform bacteria are indicators of fecal pollution,

which can pose serious health risks if consumed. By following the guidelines outlined in this standard,

organizations and laboratories can accurately assess the microbiological quality of water and take appropriate

measures to prevent contamination or outbreaks of waterborne diseases.

Methods used in BS EN ISO 9308-8:2019

BS EN ISO 9308-8:2019 provides detailed methods for the detection and enumeration of E. coli and coliform bacteria

in water. These methods involve various steps, including sample collection, filtration, membrane transfer, culture

techniques, and biochemical and serological identification. The standard specifies the equipment, materials,

reagents, and incubation conditions necessary for accurate testing. It also gives guidelines for the validation of

test methods and the interpretation of results.

Conclusion

BS EN ISO 9308-8:2019 is an important technical document that sets the standard for the quantitative measurement

of E. coli and coliform bacteria in water. By using the methods described in this standard, organizations can

ensure the safety and quality of their water resources. This helps to protect public health and prevent waterborne

diseases. Compliance with this standard is crucial for laboratories, regulatory bodies, and other entities involved

in water testing and monitoring.
