Table 8
Annual sampling frequencies for Group A4 parameters: water supply zones
| (1) Estimated population of water supply zone | (2) Standard sampling frequency per year |
|---|---|
| <100 | 2 |
| 100-4,999 | 4 |
| 5,000-9,999 | 12 |
| 10,000-29,999 | 24 |
| 30,000-49,999 | 36 |
| 50,000-79,999 | 52 |
| 80,000-100,000 | 76 |
Table 9
Annual sampling frequencies for Group B1 parameters: water supply zones
| (1) Estimated population of water supply zone | (2) Standard sampling frequency per year |
|---|---|
| <100 | 1 |
| 100-4,999 | 4 |
| 5000-100,000 | 8 |
Table 10
Annual sampling frequencies for Group A1: water supply zones
| (1) Estimated population of water supply zone | (2) Standard sampling frequency per year |
|---|---|
| <100 | 4 |
| ≥100 | 12 per 5,000 population |
For the purposes of this table, where the population is not an exact multiple of 5,000, the population figure must be rounded up to the nearest multiple of 5,000.
