1 The total viable colony count should be measured within 12 hours of bottling, with the sample water being kept at a constant temperature during that 12 hour period. Any increase in the total viable colony count of the water between 12 hours after bottling and the time of sale should not be greater than that normally expected. | |||
2 In 72 hours on agar-agar or an agar-gelatine mixture. | |||
3 In 24 hours on agar-agar. | |||
| Item | Parameter | Units of Measurement | Maximum Concentration or Value |
|---|---|---|---|
| 1. | Escherichia coli (E coli) | number/250 ml | 0/250 ml |
| 2. | Enterococci | number/250 ml | 0/250 ml |
| 3. | Pseudomonas aeruginosa | number/250ml | 0/250 ml |
| 4. | Colony count 22ºC | number/ml | 100/ml 12 |

1 The parametric value refers to the residual monomer concentration in the water as calculated according to specifications of the maximum release from the corresponding polymer in contact with the water. | |||
2 The concentration (mg/l) of nitrate divided by 50 added to the concentration (mg/l) of nitrite divided by 3 must not exceed 1. | |||
3 “Pesticides” means: | |||
– organic insecticides, | |||
– organic herbicides, | |||
– organic fungicides, | |||
– organic nematocides, | |||
– organic acaricides, | |||
– organic algicides, | |||
– organic rodenticides, | |||
– organic slimicides, and | |||
– related products (inter alia, growth regulators) and their relevant metabolites, degradation and reaction products. | |||
Only those pesticides which are likely to be present in a given water need to be monitored. | |||
4 The maximum concentration applies to each individual pesticide. In the case of aldrin, dieldrin, heptachlor and heptachlor epoxide the maximum concentration is 0.030 µg/l. | |||
5 The maximum concentration for “total substances” refers to the sum of the concentrations of all individual pesticides detected and quantified in the monitoring procedure. | |||
6 The specified compounds are benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(ghi)perylene, indeno(1,2,3-cd)pyrene. | |||
7 The maximum concentration specified applies to the sum of the concentrations of the specified parameters. | |||
