# The Water Intended for Human Consumption (Private Supplies) (Scotland) Regulations 2017, Paragraph 6: Minimum sampling and analysis frequencies

Extent: S

The minimum sampling and analysis frequency for the monitoring of radon, tritium and indicative dose in water (where required by this schedule) from a private water supply system or from a tanker or used in a food production undertaking is set out in the following table.
Volume of water (in m3) distributed or produced each day within a supply zone (Note 1)
Number of samples per year
(Notes 2 and 3)
> 0
≤ 100
1
> 100
≤ 1,000
1
> 1,000
≤ 10,000
1, plus 1 for each 3,300 m3/day and part thereof of the total volume
> 10,000
≤ 100,000
3, plus 1 for each 10,000 m3/day and part thereof of the total volume
> 100,000
10, plus 1 for each 25,000 m3/day and part thereof of the total volume
Note 1: The volumes are calculated as averages taken over a year. The number of inhabitants in a 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.
Note 2: As far as possible, the number of samples must be distributed equally in time and location.
Note 3: In the event of intermittent short-term supply the monitoring frequency of water distributed by tankers must be decided by each enforcing authority in relation to the water.
