Paragraph 3 F1
(1)
Other parameters, except radon, tritium and indicative dose, (“Group B parameters”) must be monitored at least at the frequencies determined in accordance with the table below.
(2)
In the table, “Group A parameters” is to be construed in accordance with paragraph 2.
Minimum frequency of sampling and analysis for compliance monitoring
| Volume of water (in m3) distributed or produced each day within a water supply zone (Notes 1 and 2) | Group A parameters: number of samples per year | Group B parameters: number of samples per year | |
|---|---|---|---|
| > 0 | ≤ 10 | 2 | 1 |
| > 10 | ≤ 1,000 | 4 | 1 |
| > 1,000 | ≤ 10,000 | 4 for the first 1,000 m3/day of the total volume, plus 3 for each additional 1,000 m3/day and part thereof | 1 for the first 1,000 m3/day of the total volume, plus 1 for each additional 4,500 m3/day and part thereof |
| > 10,000 | ≤ 100,000 | 4 for the first 1,000 m3/day of the total volume, plus 3 for each additional 1,000 m3/day and part thereof | 3 for the first 10,000 m3/day of the total volume, plus 1 for each additional 10,000 m3/day and part thereof |
| > 100,000 | 4 for the first 1,000 m3/day of the total volume, plus 3 for each additional 1,000 m3/day and part thereof | 12 for the first 100,000 m3/day of the total volume, plus 1 for each additional 25,000 m3/day and part thereof | |
| Note 1: The volumes are calculated as averages taken over a year. | |||
| Note 2: The number of inhabitants in a water supply zone may be used instead of the volume of water to determine the minimum frequency, assuming water consumption of 200 litres/day per person. | |||
