Comprehensive Guide to WHO Guidelines for Testing Ammonia in Water: A Laboratory Testing Service by Eurolab
The World Health Organization (WHO) guidelines for testing ammonia in water are established to ensure the safety of drinking water and other water bodies. These guidelines are based on international standards, such as ISO 11731-1:2005, which specifies the method for determining the concentration of ammonia in water.
International Standards
ISO 11731-1:2005 (Water quality Determination of ammonia Part 1: Selective extraction method)ISO 11731-2:2014 (Water quality Determination of ammonia Part 2: Titrimetric methods)ASTM D1429-09 (Standard Test Method for Ammonia in Water)EN 12260-5:2007 (Chemical analysis of water - Determination of ammonia)National Standards
In the United States, the Environmental Protection Agency (EPA) regulates drinking water quality under the Safe Drinking Water Act.The European Union has established a Drinking Water Directive that sets standards for drinking water quality.Standard Development Organizations
International Organization for Standardization (ISO)American Society for Testing and Materials (ASTM)European Committee for Standardization (CEN)Evolution of Standards
Standards are regularly reviewed and updated to reflect new scientific research, technological advancements, and changes in regulations. For example, ISO 11731-1:2005 was revised in 2014 to improve the accuracy and precision of ammonia measurement.
Standard Compliance Requirements
Drinking water suppliers must comply with WHO guidelines for testing ammonia in water.Manufacturers of water treatment chemicals must comply with national and international standards for product safety and efficacy.The presence of ammonia in drinking water can pose health risks to consumers. Ammonia can react with other substances in the water to form toxic compounds, such as nitrosamines. WHO guidelines recommend testing for ammonia to ensure compliance with safety standards.
Business and Technical Reasons
Compliance with regulations and industry standardsProtection of consumer health and safetyPrevention of equipment damage and maintenance costsCost savings through early detection of contamination Failure to test for ammonia can lead to:
Health risks to consumersEquipment damage and costly maintenanceNon-compliance with regulations and industry standardsLoss of business reputation and customer trustIndustries and Sectors that Require This Testing
Drinking water suppliersWater treatment manufacturersIndustrial processes using waterPower generation plants using cooling systemsThe presence of ammonia in water can pose risks to:
Human health through consumption or skin contactEquipment damage through corrosion or scalingEnvironmental pollution through release into water bodiesQuality Assurance and Quality Control Aspects
Eurolab follows strict quality control procedures, including:
Regular calibration and validation of testing equipmentUse of certified reference materials for measurement verificationDocumentation and record-keeping for all testing activitiesThe WHO guidelines for testing ammonia in water recommend the following:
Sampling procedure: Collect a representative sample from the water sourceSample preparation: Dilute the sample to achieve a concentration of 10 mg/LTesting equipment: Use a spectrophotometer or gas detector tubeMeasurement and analysis: Measure absorbance at 625 nm (spectrophotometer) or use a gas detector tubeEurolab provides detailed test reports, including:
