Water & waste water

Analysis Laboratory - Water & Wastewater

Water is essential for any life on Earth and any enterprise. And it is therefore highly vulnerable for pollution. Water & Inorganic and Wastewater laboratories of CML offer a variety of tests for quantification of chemical and physical parameters in water and waste water according to the standards method in compliance with ISO 17025:2018 quality system.

 

Water and Wastewater are analyzed to ensure compliance with national environmental requirements and regulations. We are proud to be the countries independent service provider for Health Ministry to perform chemical analysis of raw water and packaged/ bottled drinking water as per the relevant standards. The laboratories provide its expertly for National water quality monitoring studies for Baseline monitoring and EIAs. Onsite sampling service is also available at the laboratory.

 

Instruments

 

The water and wastewater analysis laboratories are equipped with basic instruments such as pH/ ISE/ EC meters, incubators to high end equipment like Ion chromatography systems. All equipment are timely calibrated and traceability is maintained.
