| 60 | Sulphite-reducing clostridium | 20 | - | - | most probable number < 1 |
Water for human use must not contain any pathogens.
In order to complete the microbiological investigation of water intended for human use, investigations into the following are to be performed - where necessary - in addition to the germs listed in table E:
- salmonellae
- pathogenic staphylococci
- faecal bacteriophages
- enteroviruses.
Furthermore, such water should not contain
- parasites
- algae
- or other figurative elements (animalcula).
(1) Insofar as a sufficient number of specimens is examined (95% concurring results).

- Given compliance with parameters 57, 58, 59 and 60 and an
absence of pathogens, (page 9) the Member States may choose to allow domestic use of water
where the colony count exceeds the MPC values prescribed for parameter 62. - The MPC values are to be measured within 12 hours after filling containers; the water samples are to be kept at a constant temperature during this 12 hour period. |
(1) In the case of disinfected water the corresponding values must be clearly lower on leaving the treatment system
(2) A check must always be made if values are exceeded and this applies also to consecutive samples

| 2 | Hydrogen ion concentration | pH | ||
| 3 | Alkalinity | mg/l HCO3 | 30 | The water should not be aggressive |
| 4 | Dissolved oxygen | |||
NB:
- The provisions concerning hardness, pH, dissolved oxygen and calcium likewise apply to desalinated water.
- If the water is softened before being supplied to the consumer on account of its excessive natural hardness in line with table F, its sodium content may be in excess of the values given in the column "maximum permissible concentration" in exceptional circumstances. Endeavours are made to keep this content as low as possible and protection of the health of the population must be guaranteed.
