| Chloride | 250 | mg/l | Note 1 |
Clostridium perfringens (including spores) | 0 | number/100 ml | |
| Colour | Acceptable to consumers and no abnormal change | ||
| Colour | 20 | mg/l Pt/Co | |
| Conductivity | 2500 | μS/cm at 20 °C | Note 1 |
| Hydrogen ion concentration | ≥ 6.5 and ≤ 9.5 | pH units | Notes 1 and 3 |
| Iron | 200 | μg/l | Note 2 |
| Manganese | 50 | μg/l | Note 2 |
| Odour | Acceptable to consumers and no abnormal change | ||
| Oxidisability | 5.0 | mg/l O2 | Note 4 |
| Sulphate | 250 | mg/l | Note 1 |
| Sodium | 200 | mg/l | |
| Taste | Acceptable to consumers and no abnormal change | ||
| Colony count 22 °C | No abnormal change | ||
| Coliform bacteria | 0 | number/100 ml | Note 5 |

Parametric values for radon, tritium and indicative dose—
| Parameter | Parametric value | Unit | Notes |
|---|---|---|---|
| Radon | 100 | Bq/l | Note 8 |
| Tritium | 100 | Bq/l | Note 9 |
| Indicative dose | 0.10 | mSv | |
| Note 1: The water must not be aggressive. | |||
| Note 2: This parameter must be measured if the water originates from, or is influenced by, surface water. | |||
| Note 3: For still water put into bottles or containers, the minimum value may be reduced to 4.5 pH units. For water put into bottles or containers which is naturally rich in or artificially enriched with carbon dioxide, the minimum value may be lower. | |||
| Note 4: This parameter need not be measured if total organic carbon is analysed. | |||
| Note 5: For water put into bottles or containers the unit is number/250 ml. | |||
| Note 6: This parameter need not be measured for supplies of less than 10,000 m3 of water a day. | |||
| Note 7: If the water is subject to treatment to improve its quality, each enforcing authority in relation to the water must strive to ensure that the water, at the point at which it flows out from the treatment works, does not exceed 1.0 nephelometric turbidity units. | |||
| Note 8: Remedial action is to be deemed justified on radiological protection grounds, without further consideration, where radon concentrations exceed 1,000 Bq/l. | |||
| Note 9: Elevated levels of tritium may indicate the presence of other artificial radionuclides. If the tritium concentration exceeds its parametric value, each enforcing authority in relation to the water must also carry out an analysis of the presence of other artificial radionuclides. | |||
