Quality Criteria for Drinking Water
The Drinking Water Directive 2020/2184 concerns the quality of water intended for human consumption. Drinking water is wholesome and clean if it’s: (a) free from any micro-organisms and parasites and from any substances which, in numbers or concentrations, constitute a potential danger to human health; (b) meets the minimum requirements set out in Parts A, B and D of Annex I. Indicators parameters set out in Part C of Annex I shall also be monitored, as they can help to identify water treatment.
| Application Name | Maximum Threshold | Part | Notes(s) | |
|---|---|---|---|---|
|
Drinking water |
50 mg/l |
B Part B - Chemical parameters |
Member States shall ensure that the condition [nitrate]/50 + [nitrite]/3 ≤ 1, where the square brackets signify the concentrations in mg/l for nitrate (NO3) and nitrite (NO2), is complied with and that the parametric value of 0,10 mg/l for nitrites is complied with ex water treatment works |
