WATER TESTING
Our water testing services cover a wide range of parameters to ensure the safety and quality of drinking water, groundwater, and
industrial water supplies. We use advanced techniques and equipment to analyze physical, chemical, and biological properties,
including:
- pH, TDS, TSS, and turbidity
- Heavy metals like lead, arsenic, and mercury
- Microbiological contaminants such as E. coli add total coliform
- Effluent Testing
We offer comprehensive effluent testing to help industries meet regulatory standards and ensure environmental compliance. Our
services include: COD, BOD, and TOC analysisHeavy metal and nutrient testing.
1. Types of Water Testing in NABL Labs:
NABL-accredited laboratories are equipped to test various types of water, including drinking water, industrial water, wastewater, and
groundwater. They conduct tests for numerous water quality parameters, such as:
- Physical parameters: Turbidity, temperature, color, odour, taste, pH, and total dissolved solids (TDS).
- Chemical parameters: Chloride, hardness (CaCO₃), alkalinity, dissolved oxygen, chemical oxygen demand (COD), biological oxygen demand (BOD), metals like lead, mercury, arsenic, fluoride, and nitrates.
- Microbiological parameters: Total coliforms, fecal coliforms, E. coli, and other harmful microorganisms.
2. NABL Accreditation Standards:
The NABL accreditation for water testing labs is based on international standards, such as:
- ISO/IEC 17025: General requirements for the competence of testing and calibration laboratories.
- S 10500: Drinking water specifications.
- IS 14724: Guidelines for water quality monitoring.
- IS 14724: Guidelines for water quality monitoring.
These standards ensure that the laboratories are following the necessary protocols for quality and accuracy in water testing.
3. Importance of NABL Testing for Water
- Accuracy and Reliability: NABL accreditation assures the accuracy of test results, which is crucial for ensuring the safety and quality of water.
- Compliance with Regulations: For industries or municipalities, NABL-certified water tests help in complying with environmental regulations and safety standards.
- Public Health: Ensuring that drinking water is free from harmful bacteria and chemicals helps prevent waterborne diseases.
- Environmental Protection: For wastewater testing, NABL accreditation ensures that water being discharged into natural bodies meets regulatory standards and does not harm the environment.
4. Benefits of NABL Accreditation
- Credibility: NABL accreditation is a globally recognized symbol of laboratory competence.
- Compliance: For industries and government bodies, NABL accreditation helps in meeting regulatory requirements.
- Consistency: Accredited labs provide consistent and repeatable results.
- Trust: Consumers and stakeholders trust the results from NABL-accredited laboratories.
5. Steps in Water Analysis
- Collection of Samples: Water samples must be collected properly, using sterilized containers, ensuring no contamination.
- Analysis in the Lab: The samples are analyzed according to the standard testing methods, following strict protocols.
- Reporting: Results are provided in reports that detail the findings, including any parameters that exceed permissible limits.
6. Common Water Testing Parameters:
- pH Level: Measures the acidity or alkalinity of the water.
- Turbidity: Cloudiness or haziness of water caused by suspended particles.
- Total Dissolved Solids (TDS): Measures the amount of dissolved substances in the water.
- Heavy Metals: Such as arsenic, lead, mercury, which are toxic even in low concentrations.
- Microbial Contamination: Indicates the presence of bacteria, viruses, or protozoa that can cause diseases.
7. Conclusion
NABL accreditation for water testing ensures that laboratories providing water analysis follow the highest standards of quality and competence.
The testing is vital to maintaining public health, protecting the environment, and ensuring compliance with regulations for water quality.
Whether it’s for drinking water or industrial wastewater, NABL-accredited laboratories are essential for ensuring water safety and quality.
