Regulation 24 (2)(a)
SCHEDULE 8Monitoring for parameters other than radioactive substances in water bottled and labelled as “spring water” and bottled drinking water
PART 1Check monitoring
Sampling
1. A district council must undertake check monitoring in accordance with this Part.
2. Check monitoring means sampling water bottled and labelled as “spring water” and bottled drinking water for each parameter listed in Table 1 in the circumstances listed in that table in order—
(a)to determine whether the water complies with the parametric concentrations or values in Parts 2 and 3 of Schedule 7;
(b)to provide information on the organoleptic and microbiological quality of the water; and
(c)to establish the effectiveness of the treatment of the water, including disinfection.
Table 1
| Parameter | Circumstances |
|---|---|
| Aluminium | Necessary only when used as flocculant |
| Ammonium | In all supplies |
| Colour | In all supplies |
| Conductivity | In all supplies |
| Clostridium perfringens (including spores) | Necessary only if the water originates from or is influenced by surface water |
| Escherichia coli (E. Coli) | In all supplies |
| Hydrogen ion concentration | In all supplies |
| Iron | Necessary only when used as flocculant |
| Nitrite | Necessary only when chloramination is used as a disinfectant |
| Odour | In all supplies |
| Pseudomonas aeruginosa | In all supplies |
| Taste | In all supplies |
| Colony count 22°C and 37°C | In all supplies |
| Coliform bacteria | In all supplies |
| Turbidity | In all supplies |
Frequency of sampling
3. Sampling must be carried out at frequencies specified in Table 2.
Table 2
| Volume of water produced for offering for sale in bottles or containers each day (m3)(1) | Number of samples per year |
|---|---|
(1) The volumes are calculated as averages taken over a calendar year. | |
| ≤ 10 | 1 |
| > 10 ≤ 60 | 12 |
| > 60 | 1 for each 5m3 and part thereof of the total volume |
PART 2Audit Monitoring
Sampling
1. A district council must undertake audit monitoring in accordance with this Part.
2. Audit monitoring means sampling water bottled and labelled as “spring water” and bottled drinking water for each parameter listed in Part 2 and 3 of Schedule 7 (other than parameters already being sampled under check monitoring) in order to—
(a)provide the information necessary to determine whether the water complies with the parametric concentrations or values in Schedule 7;
(b)check that, if disinfection is used, disinfection by-products are kept as low as possible without compromising disinfection; and
3. Sampling must be carried out at frequencies specified in Table 3.
Table 3
| Volume of water produced for offering for sale in bottles or containers each day (m3)(1) | Number of samples per year |
|---|---|
(1) The volumes are calculated as averages taken over a calendar year. | |
| ≤ 10 | 1 |
| > 10 ≥ 60 | 1 |
| > 60 | 1 for each 100 m3 and part thereof of the total volume |
