The type and sensitivity of the analysis depends on the purpose of the analysis and the anticipated use of the water.
Chemical water analysis is carried out on water used in industrial processes, on waste-water stream, on rivers and stream, on rainfall and on the sea.
In all cases the results of the analysis provides information that can be used to make decisions or to provide re-assurance that conditions are as expected.
The analytical parameters selected are chosen to be appropriate for the decision making process or to establish acceptable normality.
Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters.
Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry.
In water treatment plants producing drinking water and in some industrial processes using products with distinctive taste and odours , specialised organoleptic methods may be used to detect smells at very low concentrations.
