The natural quality of water in recent decades has undergone change and degradation due to various sources of pollution (e.g. municipal sewage, industrial liquid waste, detergents, agricultural liquid waste, livestock liquid waste, seawater intrusion, etc.). The main effects of water pollution are: the reduction of oxygen, the eutrophication of waters, the pollution of groundwater as well as the pollution of drinking water.
Drinking water must be clean from a physical, biological and microbiological point of view as its consumption must not endanger human health. In addition, the water must be colorless, odorless and with a pleasant taste. It must not have high hardness, contain organic substances, heavy metals nor pathogenic parasites or microbes.
Physicochemical and microbiological analyzes are carried out in the laboratory in order to examine and control the quality of water intended for consumption. In addition, in addition to drinking water, tests are carried out in the laboratory on swimming pool, swimming pool and irrigation water
Indicative of the chemical analyzes carried out in the laboratory are:
✓ Residual Chlorine
