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.
