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).

Parameter			Results: specimen quantity in ml	Guide value (GV)	Maximum permissible concentration (MPC)	Remarks
61	Colony count in water supplied directly to consumer	37°C 22°C	1 1	10(1)(2) 100(1)(2)	- -

(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

F. NECESSARY MINIMUM CONCENTRATIONS FOR WATER WHICH HAS BEEN SOFTENED AND IS SUPPLIED FOR HUMAN USE

Parameter		Method of presentation	Required minimum concentration (softened water)	Remarks
1	Total hardness	mg/l Ca	60	Calcium or equivalent cations
2	Hydrogen ion concentration	pH

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.
