Water testing is a broad description for the various procedures used to analyze water quality. Millions of water quality tests are performed every day to meet regulatory requirements and to maintain safety. Testing can be done to evaluate
the process of examining and measuring the quality, composition, and properties of water to ensure its safety and suitability for various purposes. This analysis includes examination of physical, chemical and biological parameters such as pH, turbidity, contaminants (e.g. heavy metals, bacteria), and dissolved oxygen (DO) content, the results of which are important for drinking water, agriculture, industry and environmental maintenance.
