(9) Where a parametric value is exceeded in a particular sample, the local authority must define the extent of re-sampling necessary to ensure that the measured values are representative of an average activity concentration for a full year.
(10) The local authority may, for such time as it may decide, exclude from monitoring a parameter contained in the radioactive parameters table—
(a)if it considers that the parameter in question is unlikely to be present in the supply or system at a concentration or value that poses a risk of the private water supply failing to meet the concentration, value or state specified in the radioactive parameters table in respect of that parameter,
(b)taking into account the findings of any risk assessment, and
(c)taking into account any guidance issued by the Secretary of State.
(11) The local authority must provide the Secretary of State with the grounds for a decision under paragraph (10) and the necessary documentation supporting the decision (including the findings of any surveys, monitoring or investigations carried out).

(2) A local authority may reduce the frequency of sampling for a parameter to a frequency not less than half if the local authority is of the opinion that the quality of water in the supply is unlikely to deteriorate and—
(a)in the case of the hydrogen ion parameter, the supply has no pH value that is below 6.5 and above 9.5;
(b)in all other cases, in each of two successive years the results of samples taken for the purposes of monitoring the parameter in question are constant and significantly lower than the concentrations or values referred to in Schedule 1.
(3) The local authority may set a higher frequency for any parameter if it considers it appropriate, taking into account the findings of any risk assessment, and may monitor anything else identified in the risk assessment.
3.—(1) A local authority must undertake audit monitoring in accordance with this Part.
(2) “Audit monitoring” means sampling for each parameter listed in Parts 1 and 2 of Schedule 1 (other than parameters already being sampled under check monitoring)—
(a)in order to provide information necessary to determine whether or not the private water supply satisfies each concentration, value or state prescribed in those Parts of that Schedule, and
(b)if disinfection is used, in order to check that disinfection by-products are kept as low as possible without compromising the effectiveness of disinfection.
(3) The local authority may, for such time as it may decide, exclude a parameter from audit monitoring of a private water supply—
(a)if it considers that the parameter in question is unlikely to be present in the supply or system at a concentration or value that poses a risk of the private water supply failing to meet the concentration, value or state specified in Part 1 or 2 of Schedule 1 in respect of that parameter,
(b)taking into account the findings of any risk assessment, and
(c)taking into account any guidance issued by the Secretary of State.
(4) A local authority may monitor anything else identified in the risk assessment.
4.—(1) Sampling must be carried out at the frequencies specified in Table 3.

Regulation 12
1.—(1) A local authority must ensure that each sample is—
(a)taken by a competent person using suitable equipment,
(b)representative of the water at the sampling point at the time of sampling,
(c)not contaminated in the course of being taken,
(d)kept at such a temperature and in such condition as will secure that there is no material change in what is to be measured, and
(e)analysed without delay by a competent person using suitable equipment.
(2) It must ensure that the sample is analysed using a system of analytical quality control.
(3) The system must be subjected to checking by a person who is—
(a)not under the control of either the analyst or the local authority, and
(b)approved by the Secretary of State for that purpose.
2.—(1) A local authority must ensure that each sample is analysed in accordance with this paragraph.
(2) For each parameter specified in the first column of Table 1 in Part 2 of this Schedule, the method of analysis is specified in the second column of that Table.
(3) For each parameter specified in the first column of Table 2 in Part 2 of this Schedule, the method is one that is capable of—
(a)measuring concentrations and values with the trueness and precision specified in the second and third columns of that Table, and
(b)detecting the parameter at the limit of detection specified in the fourth column of that Table.
(4) For hydrogen ion, the method of analysis must be capable of measuring a value with a trueness of 0.2 pH unit and a precision of 0.2 pH unit.
(5) The method of analysis used for odour and taste parameters must be capable of measuring values equal to the parametric value with a precision of 1 dilution number at 25°C.
(6) For these purposes—
“limit of detection” is —
three times the relative within-batch standard deviation of a natural sample containing a low concentration of the parameter, or
five times the relative within-batch standard deviation of a blank sample;
“precision” (the random error) is twice the standard deviation (within a batch and between batches) of the spread of results about the mean;
“trueness” (the systematic error) is the difference between the mean value of the large number of repeated measurements and the true value.

5.—(1) A local authority may use various reliable screening strategies to indicate the presence of radioactivity in water intended for human consumption.
(2) These strategies may include screening for—
(a)certain radionuclides, or screening for an individual radionuclide;
(b)gross alpha activity or gross beta activity screening.
6.—(1) If one of the activity concentrations exceeds 20% of the corresponding derived value or the tritium concentration exceeds its parametric value specified in the radioactive parameters table, an analysis of additional radionuclides is required.
(2) A local authority must take into account, in deciding which radionuclides are required to be measured for each supply, all relevant information about likely sources of radioactivity.
7.—(1) Subject to paragraph 6(1), the recommended screening values are—
(a)0.1 Bq/l for gross alpha activity, and
(b)1.0 Bq/l for gross beta activity(18).
(2) If the gross alpha activity exceeds 0.1 Bq/l or the gross beta activity exceeds 1.0 Bq/l, analysis for specific radionuclides is required.
(3) The Secretary of State may set alternative screening levels for gross alpha activity and gross beta activity where it is demonstrated by the local authority that the alternative levels are in compliance with an ID of 0,1 mSv.
(4) The determination by the local authority of which radionuclides to measure must be based on all relevant information about likely sources of radioactivity.
8.—(1) The ID must be calculated from—
(a)the measured radionuclide concentrations and the dose coefficients laid down in Annex III, Table A of Directive 96/29/Euratom laying down basic safety standards for the protection of the health of workers and the general public against the dangers arising from ionising radiation(19), or
(b)more recent information recognised by the Secretary of State, on the basis of the annual intake of water (730 litres for adults).
(2) Where the following formula is satisfied, it can be assumed that the ID is less than the parametric value of 0,1mSv and no further investigation is required—
Where—
“Ci(obs)” means the observed concentration of radionuclide I;
“Ci(der)” means the derived concentration of radionuclide I;
“n” means the number of radionuclides detected.

Note 1: The limit of detection must be calculated according to the ISO standard 11929: Determination of the characteristic limits (decision threshold, detection limit, and limits of confidence interval) for measurements of ionising radiation – Fundamentals and application, with probabilities of errors of 1st and 2nd kind of 0,05 each(21).
Note 2: Measurement uncertainties must be calculated and reported as complete standard uncertainties, or as expanded uncertainties with an expansion factor of 1,96 according the ISO Guide for the Expression of Uncertainty in Measurement(22).
Note 3: The limit of detection for tritium and for radon is 10% of its parametric value of 100 Bq/1.
Note 4: The limit of detection for gross alpha activity and gross beta activities are 40% of the screening values of 0,1 and 1,0 Bq/1 respectively.
Note 5: This limit of detection applies only to initial screening for ID for a new water source; if initial checking indicates that it is not plausible that Ra-228 exceeds 20% of the derived concentration, the limit of detection may be increased to 0,08 Bq/1 for routine Ra-228 nuclide specific measurements, until a subsequent re-check is required.

(This note is not part of the Regulations)
These Regulations, which apply in England, transpose requirements of Council Directive 98/83/EC on the quality of water intended for human consumption (OJ No L 330, 5.12.1998, p 32) and Council Directive 2013/51/Euratom laying down requirements for the protection of the health of the general public with regard to radioactive substances in water intended for human consumption (OJ No L 296, 7.11.2013, p 12). They revoke and replace the Private Water Supplies Regulations 2009 (S.I. 2009/3101).
These Regulations apply to private supplies of water intended for human consumption, which mean supplies of water other than a supply provided directly by a water undertaker or licensed water supplier. They define “wholesomeness” in relation to private water supplies in regulation 4 and Part 1 of Schedule 1 and impose a duty on the local authority to carry out a risk assessment of the private water supply (regulation 6) to the monitor the supply in accordance with regulations 7 to 11 and Schedule 2.
Regulation 11 and Part 3 of Schedule 3 set out the specific monitoring requirements for radioactive substances (indicative dose, radon and tritium). The indicator parameters for radioactive substances are set out in Table D in Part 3 of Schedule 1.
Once monitored, the local authority must ensure the sample is analysed in the ways set out in Schedule 3 (regulation 12). Regulation 13 sets out the requirements for new private water supplies and private water supplies that have not recently been used. The local authority must make and maintain records in respect of every private water supply in its area and must send a copy of the records to the Secretary of State (regulation 14 and Schedule 4).
Part 4 of the Regulations sets out the procedures that apply if a private water supply is unwholesome or is a potential danger to human health. Regulation 15 requires a local authority to provide certain information and advice in the event that a private water supply is a potential danger to human health. Regulation 16 requires a local authority to carry out an investigation and to take certain steps where a private water supply is unwholesome. Regulation 17 provides that, in exceptional circumstances, a local authority may grant a time-limited authorisation of different standards in respect of private water supplies.
Part 5 sets out the notice procedures that apply where a private water supply constitutes a potential danger to human health (regulation 18). It also sets out the appeal procedures (regulation 19) and the relevant penalties (regulation 20) in respect of such notices.
Part 6 sets out miscellaneous provisions including charging for fees (regulation 21 and Schedule 5), review of the Regulations by the Secretary of State (regulation 22), revocations (regulation 23) and transitional provisions (regulation 24).
