Due to its specificity the contaminants in water are determined by a separate ordinance (№ 9 MH), as some substances were not considered as harmful to other foods, but to water are normalized. For drinking water is characteristic that it participates in the production of all foods and drinks, and is also directly consumed, which makes it the source of the most serious load of certain substances and elements in the human body.
The most common contaminants in drinking water divide into several groups of substances: organic, inorganic and microbiological, as their source may be of natural origin or from human activity.
I will examine the contaminants in drinking water when considering the different groups of substances and I will specify
where they are normalized and where they are being searched.
