Comprehensive Guide to ISO 13145 Rapid Enumeration of E. coli in Fresh Water Testing Services

ISO 13145 is an international standard for the rapid enumeration of Escherichia coli (E. coli) in fresh water. This standard provides a comprehensive framework for testing and evaluating the presence of E. coli in freshwater sources, which is critical for ensuring public health and safety.

International Standards Governing ISO 13145

  • ISO 13145:2017 - Rapid enumeration of Escherichia coli (E. coli) - Part 1: General guidance on sampling

  • ISO 11731-1:1998 - Water quality Detection of E. coli Part 1: Method by inoculation into a selective medium

  • ASTM D 7683-10: Standard Test Method for Enumeration of Escherichia coli and Other Related Coliform Bacteria in Drinking Water

    • Standard Development Organizations

    Standards are developed by standard development organizations, such as the International Organization for Standardization (ISO), American Society for Testing and Materials (ASTM), and European Committee for Standardization (CEN). These organizations collaborate with industry experts, governments, and regulatory bodies to develop and maintain standards that reflect best practices and technological advancements.

    Why ISO 13145 is Needed

    E. coli contamination in fresh water poses a significant risk to public health, particularly in areas where drinking water sources are contaminated or compromised. The rapid enumeration of E. coli is crucial for:

  • Ensuring the safety of drinking water

  • Preventing waterborne illnesses and outbreaks

  • Complying with regulations and standards

    • The ISO 13145 test involves collecting a representative sample from the fresh water source, which is then processed and analyzed using a selective medium. The testing process includes:

    1. Sample Collection: Collect a representative sample from the fresh water source, following guidelines for sampling protocols.

    2. Sample Preparation: Prepare the sample according to standard procedures, including filtration or centrifugation, as required.

    3. Selective Medium: Inoculate the prepared sample into a selective medium, which inhibits the growth of non-E. coli bacteria.

    4. Incubation: Incubate the inoculated medium under controlled conditions (temperature, time, etc.).

    5. Analysis: Count the number of E. coli colonies that grow on the selective medium.

    The ISO 13145 test report includes:

    1. Test Methodology: A description of the testing process, including sampling protocols and sample preparation.

    2. Test Results: The number of E. coli colonies detected per milliliter (or other suitable unit).

    3. Certification: Certification details, such as accreditation numbers or compliance with relevant regulations.

    Why This Test Should Be Performed

    Performing the ISO 13145 test provides numerous benefits:

  • Ensures public health and safety by detecting E. coli contamination

  • Complies with regulatory requirements and standards

  • Provides quality assurance and control for water treatment processes

  • Supports innovation and research development in water management
