Drinking water, as well as beverage and food manufacturing, requires clean water. Freshwater sources can include chemical pollutants such as perfluorooctanoic acid (PFAS) and arsenic, as well as microbiological contaminants and pathogens, despite the world's small percentage of freshwater. Residual chemicals and pollutants in drinking water can exceed safe and legal limits even after treatment. Municipalities, private water treatment stations, and food and beverage manufacturing enterprises must test their water supply on a regular basis to verify that chemical and microbiological contamination levels are kept at or below statutory compliance limits. 

Testing Methods in drinking Water

These are small, single-use strips that change color to indicate the concentration of a specific chemical. Depending on the particular test, the user “activates” the paper or plastic strip by dipping it into the water sample and swishing it around, or by holding the strip in a stream of water.

Disinfectant Testing in Drinking Water

Disinfection of drinking water decreases the risk of pathogenic illnesses, however, residues and disinfection byproducts (DBPs) may be left behind, posing a health concern. Furthermore, organic and inorganic contaminants may be present in our water supply at the point of origin. To guarantee safe consumption, it is necessary to identify contaminants and DBPs.

Chemical Analysis in Drinking Water Testing

Any industry that produces, consumes, or processes drinking water is required to follow national laws and conduct frequent testing to verify that the water is free of chemical and microbiological contaminants. Aluminum, ammonium, bromate, iron, manganese, chloride, nitrate, nitrite, sulfate, chromium, and other metals are common chemical pollutants.
When some industrial environmental contaminants are suspected, further testing is carried out. In the creation of petroleum products, adhesives, medicines, paints, and refrigerants, volatile organic compounds (VOCs) are often utilized.

Microbiological Analysis in Drinking Water Testing

Microbiological water analysis is a technique for estimating the quantity of bacteria present in a sample of water and allowing for the recovery of microorganisms in order to identify them. The plate count is the method of inspection. Bacteria such as nonspecific coliforms, E. coli, and Pseudomonas are indicator organisms.
