Part A General objectives and monitoring programmes for water intended for human consumption

(1) The monitoring programmes established pursuant to regulation 14(2) for water intended for human consumption shall:

(a) verify that the measures in place to control risks to human health throughout the water supply chain from the abstraction area through treatment and storage to distribution are working effectively and that water intended for human consumption at the point of compliance is wholesome and clean;

(b) provide information on the quality of water supplied for human consumption to demonstrate that the obligations set out in regulation 5 and the parametric values set in accordance with regulation 6 are being met;

(c) identify the most appropriate means of mitigating the risk to human health.

(2) (a) The monitoring programmes established pursuant to regulation 14(2) shall include one or a combination of the following:

(i) collection and analysis of discrete water samples;

(ii) measurements recorded by a continuous monitoring process.

(b) In addition, monitoring programmes may consist of:

(i) inspections of records of the functionality and maintenance status of equipment;

(ii) inspections of the abstraction area, and of the treatment, storage and distribution infrastructure, without prejudice to monitoring requirements provided for under regulation 9(2)(c) and regulation 11(1)(b).

(3) The monitoring programmes shall also include an operational monitoring programme that provides rapid insight into operational performance and water quality problems and that allows rapid pre-planned remedial action. Such operational monitoring programmes shall be supply-specific, taking into account the outcomes of the identification of hazards and hazardous events and the risk assessment of the supply system, and shall be intended to confirm the effectiveness of all control measures in abstraction, treatment, distribution and storage.

The operational monitoring programme shall include the monitoring of the parameter turbidity at the water supply plant in order to regularly control the efficacy of physical removal by filtration processes, in accordance with the reference values and frequencies indicated in the following table (not applicable for groundwater sources where turbidity is caused by iron and manganese):

Operational parameter Reference value Turbidity at the water supply plant 0,3 NTU in 95 % of samples exceed 1 NTU Volume (m3) of water distributed or Minimum frequency of sampling analysis produced each day within a supply zone ≤ 1 000 Weekly > 1 000 to ≤ 10 000 Daily > 10 000 Continuous

Operational Reference Unit Notes parameter value Somatic 50 (for raw Plaque This parameter shall coliphages water) Forming measured if the

Units assessment indicates that (PFU)/100 is appropriate to do so. ml is found in raw water concentrations > 50 PFU/ 100 ml, it should analysed after steps of treatment train in order determine log removal the barriers in place and assess whether the risk breakthrough pathogenic viruses sufficiently under control.

(4) The competent authority shall ensure that the monitoring programmes are reviewed on a continuous basis and updated or confirmed at least every six years.

Part B Parameters and sampling frequencies

(1) List of parameters

Group A

The following parameters shall be monitored in accordance with the monitoring frequencies set out in Table 1 of item 2:

(a) Escherichia coli (E. coli), intestinal enterococci, coliform bacteria, colony count 22 °C, colour, turbidity, taste, odour, pH and conductivity;

(b) other parameters identified as relevant in the monitoring programme, in accordance with regulation 6(3) and, where relevant, through a risk assessment of the supply system as set out in regulation 10 and Part C.

Under specific circumstances, the following parameters shall be added to the Group A parameters:

(a) ammonium and nitrite, if chloramination is used;

(b) aluminium and iron, if used as water treatment chemicals.

Escherichia coli (E. coli) and intestinal enterococci are considered core parameters and their monitoring frequencies shall not be the subject of a reduction due to a risk assessment of the supply system in accordance with regulation 10 and Part C. They shall always be monitored at least at the frequencies set out in Table 1 of item 2.

Group B

In order to determine compliance with all parametric values set out in these regulations, all other parameters not analysed under Group A and set in accordance with regulation 6, except for parameters in Part D of the Second Schedule, shall be monitored at least at the frequencies set out in Table 1 of item 2, unless a different sampling frequency is determined on the basis of a risk assessment of the supply system carried out in accordance with regulation 10 and Part C.

3 m /d and part total volume

Note 1: A supply zone is a geographically defined area within which water intended for human consumption comes from one or more sources and within which the water quality may be considered as being approximately uniform.

Note 2: The volumes are calculated as averages taken over a calendar 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 l/(day*capita).

Note 3: The frequency indicated is calculated as follows: e.g. 4 3 300 m /d = 16 samples for Group A parameters (4 for the first 1 000 3 3 m /d + 12 for additional 3 300 m /d).

Note 4: For water suppliers, when an exemption has not been granted under regulation 4(3)(b), the competent authority shall lay down the minimum sampling frequency for parameters of Groups A and B, provided that core parameters are monitored at least once per year.

Note 5: The competent authority may reduce the sampling frequency provided that all parameters set in accordance with regulation 6 are monitored at least once every six years and are monitored in cases where a new water source is integrated into the water supply system or changes to that system, as a result of which a potentially adverse effect on the quality of water is to be expected, are made. Part C Risk assessment and risk management of the supply system

(1) Based on the outcome of the risk assessment of the supply system as referred to in regulation 10, the list of parameters considered in the monitoring shall be extended and the sampling frequencies set out in Part B shall be increased, where any of the following conditions is fulfilled:

(a) the list of parameters or frequencies set out in this Schedule is not sufficient to fulfil the obligations imposed under regulation 14(1);

(b) additional monitoring is required for the purposes of regulation 14(5);

(c) it is necessary to provide the assurances set out in item 1(a) of Part A;

(d) increasing the sampling frequencies is necessary pursuant to regulation 9(4)(a).

(2) As a result of a risk assessment of the supply system, the list of parameters considered in the monitoring and the sampling frequencies set out in Part B may be reduced provided that all of the following conditions are met:

(a) the location and frequency of sampling is determined in relation to the parameter’s origin, as well as the variability of, and long-term trend regarding its concentration, taking into account regulation 7;

(b) as regards reducing the minimum sampling frequency of a parameter, the results obtained from samples collected at regular intervals over a period of at least three years, from sampling points representative of the whole supply zone, are all less than 60% of the parametric value;

(c) as regards removing a parameter from the list of parameters to be monitored, the results obtained from samples collected at regular intervals over a period of at least three years, from sampling points representative of the whole supply zone, are all less than 30% of the parametric value;

(d) as regards removing a parameter from the list of parameters which shall be monitored, the decision is based on the outcome of the risk assessment that takes into account the results of monitoring of sources of water intended for human consumption and confirms that human health is protected from the adverse effects of any contamination of water intended for human consumption, as laid down in regulation 2(2);

(e) as regards reducing the sampling frequency of a parameter or removing a parameter from the list of parameters to be monitored, the risk assessment confirms that no factor that may be reasonably anticipated is likely to cause deterioration of the quality of the water intended for human consumption.

When monitoring results, demonstrating that the conditions set out in items (2)(b) to (2)(e) are met, are already available by 12th January 2021, those monitoring results may, from that date, be used to adapt the monitoring following the risk assessment of the supply system.

Where adjustments of monitoring have already been implemented following risk assessment of the supply system in accordance, inter alia, with Part C of Annex II of Directive 98/83/EC of 3 November 1998 on the quality of water intended for human consumption, the competent authority may provide for the possibility to confirm their validity without requiring monitoring in accordance with items 2(b) and 2(c) over a further period of at least three years from points representative of the whole supply zone.

Part D Sampling methods and points

(1) Sampling points shall be determined so as to ensure compliance with regulation 7(1). In the case of a distribution network, the competent authority assisted by the corporation established by the Water Services Corporation Act (Cap. 355) may take samples within the supply zone or at the treatment works for particular parameters if it can be demonstrated that there would be no adverse change to the measured value of the parameters concerned. As far as possible, the number of samples shall be distributed equally in time and location.

(2) Sampling at the point of compliance shall meet the following requirements:

(a) the compliance samples for certain chemical parameters, in particular copper, lead, and nickel, shall be taken at the consumers’ tap without prior flushing. A random daytime sample of one litre volume shall be taken. As an alternative, the competent authority may use fixed stagnation time methods that better reflect the national situation, such as the average weekly intake by consumers, provided that, at the supply zone level, this does not result in fewer cases of non-compliance than using the random daytime method;

(b) the compliance samples for microbiological parameters at the point of compliance shall be taken and handled in accordance with EN ISO 19458, sampling purpose B.

(3) The samples for Legionella in domestic distribution systems shall be taken at risk points for proliferation of Legionella, points representative for systemic exposure to Legionella, or both. The competent authority shall establish guidelines for sampling methods for Legionella.

(4) Sampling in the distribution network, with the exception of sampling at the consumers’ tap, shall be in accordance with ISO 5667-5. For microbiological parameters, samples in the distribution network shall be taken and handled in accordance with EN ISO 19458, sampling purpose A. FOURTH SCHEDULE (Regulation 12)
