Frequency of sampling
4. Sampling for Group B parameters must be carried out at the frequencies specified in Table 3.
Table 3
Sampling frequency for Group B parameters
| Volume m3/day | Sampling frequency per year |
|---|---|
| ≤10 | 1 |
| ˃ 10 ≤ 3,300 | 2 |
| ˃ 3,300 ≤ 6,600 | 3 |
| ˃ 6,600 ≤ 100,00 | 4 |
| ˃ 10,000 ≤ 100,000 | 3 + 1 for each 10,000 m3/day of the total volume (rounding up to the nearest multiple of 10,000 m3/day) |
| ˃ 100,000 | 10 + 1 for each 25,000 m3/day of the total volume (rounding up to the nearest multiple of 25,000 m3/day) |
