(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.

[F13(10A) The local authority may exclude the indicative dose parameter from monitoring, or reduce the frequency of monitoring in respect of that parameter, for such period as it may decide provided that the parameter is—

InvestigationsU.K.

16.—(1) A local authority must carry out an investigation to establish the cause if it suspects that a private water supply is unwholesome or that an indicator parameter does not comply with the concentrations or values prescribed in Part 2 or 3 of Schedule 1.

(2) Once a local authority has carried out an investigation and established the cause of the water being unwholesome, it must act in accordance with paragraphs [F18(3), (4) and (6) as appropriate].

(3) If the cause of the water being unwholesome is due to the distribution system within a domestic premises (whether or not the water is made available to the public in those premises), the local authority must promptly inform the people likely to be affected and offer them advice on measures necessary for the protection of human health.

(4) In addition to the duty in paragraph (3) (where it applies), if the cause of the water being unwholesome is due to the circumstances described in paragraph (5), the local authority must—

(a)if the water is a potential danger to human health and the conditions in regulation 18 are fulfilled, serve a notice under that regulation, or

(b)within 28 days of [F19establishing the cause] and if appropriate remedial action has not been taken, serve a notice in accordance with section 80 of the Act (remedial powers of local authorities in relation to private supplies) unless the local authority grants an authorisation in accordance with regulation 17(2).

(5) The circumstances in this paragraph are—

(a)if the cause of the water being unwholesome is due to the distribution system within domestic premises where water is made available to the public;

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.

Screening for certain radionuclides, or screening for an individual radionuclideU.K.

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.

Screening strategies for gross alpha activity and gross beta activityU.K.

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 M15.

(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.

Marginal Citations

M15Where appropriate, gross beta activity may be replaced by residual beta activity after subtraction of the K-40 activity concentration.

Calculation of the IDU.K.

8.—(1) The ID must be calculated from—

(a)the measured radionuclide concentrations and the dose coefficients [F44referred to as “standard values and relationships” in Article 13, and recommended for the estimation of doses from internal exposure in the definition of “standard values and relationships” in Article 4(96), of Council Directive 2013/59/Euratom laying down basic safety standards for protection against the dangers arising from exposure to ionising radiation, 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—

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 M18.

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.

Explanatory Note

(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).
