Chemical purity of water is assessed for a wide variety of different chemicals depending on the type of water and applicable local legislation.
Chemical analysis of water can include testing for nitrogen compounds, dissolved heavy metals, and total and dissolved organic carbon.
Common water monitoring applications include:
- Determination of suspended solids in waterusing for example glass fiber filters.
- Chemical analyses of for example heavy metals, dissolved organic carbons (DOC), and ions.
- Microbiological analyses using membrane based microfiltration methods

Drinking water supply and distribution systems around the world (a critical and interdependent component of a nation’s infrastructure) are vulnerable to both intentional and accidental contamination. Unusual water quality may serve as a warning of potential contamination. The available physico-chemical sensors utilize general water quality parameters, such as free chlorine, oxidation reduction potential (ORP), total organic carbon (TOC), turbidity, pH, dissolved oxygen, chloride, ammonia, nitrate to detect the contamination. Generally, one or more of these water quality parameters will change due to the injection of a contaminant. However, no single chemical sensor responds to all possible contaminants nor can they give any indication of the potential toxicity of complex mixtures.
