Comprehensive Guide to WHO Guidelines for Testing Turbidity in Drinking Water Laboratory Testing Service Provided by Eurolab

The World Health Organization (WHO) has established guidelines for testing turbidity in drinking water, which is a critical parameter in ensuring the safety and quality of potable water. The WHO guidelines are based on international standards and regulations, including those from the International Organization for Standardization (ISO), American Society for Testing and Materials (ASTM), European Committee for Standardization (CEN), Turkish Standards Institution (TSE), and others.

International and National Standards

The relevant international standards for testing turbidity in drinking water include:

  • ISO 7027:1999, Water quality Determination of turbidity Nephelometric method

  • ASTM D1880-14, Standard Test Method for Turbidity of Water

  • CEN/TS 28710-1:2015, Drinking water Determination of total and soluble solids by evaporation method

  • TSE EN ISO 7027:2002, Suyu Kalite Belirleme - Nefelometrik Yöntemle Bulanıklik (Turbidity) Ölçme

    • These standards provide the framework for laboratory testing services to ensure accurate and reliable results. The national standards are adapted from international standards to meet local regulatory requirements.

    Standard Development Organizations

    The test conditions and methodology used by Eurolab are based on the relevant international standards, including ISO 7027:1999 and ASTM D1880-14. The step-by-step explanation of the testing process is as follows:

    1. Sample Preparation: The drinking water sample is prepared according to the standards requirements.

    2. Testing Equipment and Instruments Used: A nephelometer is used for turbidity measurements.

    3. Testing Environment: The test is performed in a controlled environment with minimal disturbance.

    4. Data Collection and Analysis: Data is collected using a nephelometer, and results are analyzed according to the standards requirements.

    Nephelometric Method

    The nephelometric method is a widely accepted technique for determining turbidity. It involves measuring the amount of light scattered by suspended solids or other contaminants in the water sample.
