Annex I, Part A - Priority Substances & Pollutants in water

This list contains environmental quality standards (EQS), including annual averages and maximum allowable concentrations, for priority substances and certain other pollutants, as provided for in Article 16 of Directive 2000/60/EC establishing a framework for Community action in the field of water policy.

Notes
6 For Cadmium and its compounds (No 6) the EQS values vary depending on the hardness of the water as specified in five class categories (Class 1: < 40 mg CaCO3/l, Class 2: 40 to < 50 mg CaCO3/l, Class 3: 50 to < 100 mg CaCO3/l, Class 4: 100 to < 200 mg CaCO3/l and Class 5: ≥ 200 mg CaCO3/l).

12 Unless otherwise specified, the EQS parameter expressed as an annual average value (AA-EQS) applies to the total concentration of all isomers.

13 Inland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies.

20 The EQS values may vary depending on the hardness of the water as specified in five class categories
