Water is one of the most important & precious natural resources available to the living organisms on earth. It is precious because it is synonymous with ‘Life’ on earth. Its importance is manifold; the significant role being played by it is in the life saving process or survival involving every living organism on this planet, be it plants, animals, fish & human beings. The existence & availability of Water on our planet occurs through the ‘Water Cycle’ (or the Hydrologic Cycle), which explains all the dynamic processes involving Water.
The two important aspects regarding Water in the contemporary world are its Quantity & Quality. Unfortunately, both these aspects have become growing concerns for the entire world. Various anthropogenic adverse activities, including population boom, have led to shortages in the supply of Water in various parts of the globe, and also degraded the Quality of Water. Quality of Water refers to the ‘Suitability’ of a particular type of Water for a specific purpose. The various purposes for which Water is used include drinking, irrigation, construction, recreational activities like swimming, aquatic life etc. The Specifications or Suitability of a particular type of Water differ from that of another one. Hence, various Standards & Guidelines have been established which specify the Suitability of a particular type of Water according to certain criteria. The Criteria for assessing the Quality of Water are:-
Color, Odour, Taste, Temperature, Turbidity, etc. These tests generally should precede any other test.
pH, Acidity, Alkalinity, Hardness, Dissolved Oxygen, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Concentration of Heavy & toxic metals like Mercury, Lead, Arsenic, Cadmium etc., Inorganic ions like Nitrate, Nitrite etc., and Pesticides etc. The majority of tests conducted on Water fall under this category as these parameters have significant effects on the Quality of Water.
Presence & Quantification of various microorganisms. These microorganisms can be Bacteria, Viruses, or Parasites which can cause several diseases & hence pose a threat to human health. Examples include E.coli, Salmonella, Legionella spp., Faecal coliform counts, Vibrio cholerae, Enteroviruses etc.
These parameters include testing of radioactive particles or residues like alpha, beta, gamma which find their way into Water bodies as a result of decay of minerals natural deposits. High levels of radioactive particles or residues can increase the risk of cancers in human beings.
