[F1SCHEDULE 1ASMONITORING: MINIMUM REQUIREMENTS

PART BSStandard parameters and frequencies

3.(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.S

(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≤ 1021
> 10≤ 1,00041
> 1,000≤ 10,0004 for the first 1,000 m3/day of the total volume, plus 3 for each additional 1,000 m3/day and part thereof1 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≤ 100,0004 for the first 1,000 m3/day of the total volume, plus 3 for each additional 1,000 m3/day and part thereof3 for the first 10,000 m3/day of the total volume, plus 1 for each additional 10,000 m3/day and part thereof
> 100,0004 for the first 1,000 m3/day of the total volume, plus 3 for each additional 1,000 m3/day and part thereof12 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.]
