What are the parameters used to evaluate the quality of water in a laboratory?

The evaluation of the quality of water in a laboratory starts with the analysis of its chemical parameters, such as pH, alkalinity, hardness, chlorides, iron and manganese, nitrogen, phosphorus, fluoride, dissolved oxygen (DO), organic matter, biochemical oxygen demand (BOD), chemical oxygen demand (COD), inorganic compounds, and organic components.
The physical parameters analyzed include temperature, taste and odor, color, turbidity, solids, and conductivity.
The presence of total coliforms indicates the presence or absence of live pathogenic microorganisms, which may have been caused by fecal contamination.
The presence of excessive total nitrogen in water can lead to uncontrolled growth of algae and the complete death of aquatic organisms, resulting in a financial impact on companies for water treatment.
The presence of alkaline earth salts in water leads to a bad taste, unpleasant odor, and laxative effect.
The total dissolved salts present in water indirectly indicate the origin and degree of contamination.
