The calculation of the arithmetic mean, the analytical method used and, where there is no appropriate analytical method meeting the minimum performance criteria, the method of applying a standard must be in accordance with implementing acts adopting technical specifications for chemical monitoring and quality of analytical results, in accordance with the Water Framework Directive. For any given surface water body, applying the MAC-EQS means that the measured concentration at any representative monitoring point within the water body does not exceed the standard. However, in accordance with section 1.3.4. of Annex V to the Water Framework Directive, the Department may introduce statistical methods, such as a percentile calculation, to ensure an acceptable level of confidence and precision for determining compliance with the MAC-EQS. With the exception of cadmium, lead, mercury and nickel (hereinafter “metals”) the standards set out in Table 46 are expressed as total concentrations in the whole water sample. In the case of metals the standards refer to the dissolved concentration i.e. the dissolved phase of a water sample obtained by filtration through a 0.45 µm filter or any equivalent pre-treatment. The Department may, when assessing the monitoring results against the standards, take into account: natural background concentrations for metals and their compounds, if they prevent compliance with the standard; and hardness, pH or other water quality parameters that affect the bioavailability of metals. ### Part 3: Boundary values for biological quality elements ## 14 Boundary values for aquatic plants and animals in transitional and coastal waters . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ## 4 Intermittent Discharge Standards . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ### Part 1: Determining Ecological Status of Surface Waters that are not designated Heavily Modified or Artificial ## 1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ## 2 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ### Part 2: Determining Chemical Status of Surface Waters ### Part 3: Determining Ecological Potential of Heavily Modified and Artificial Water Bodies ## 3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ### Part 4: Determining High Status for Morphological Elements ## 4 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ## 5 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ### Part 5: Determining Overall Status of Surface Water Bodies ## Schedule 3: Determining Quantitative status of Groundwater ## 1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ## Schedule 4 Presentation of monitoring results and classification . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ## 1 Shellfish Waters Standards . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ### Part 2: Microbial Guideline Value ## 1 Microbial Guideline Value . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ## 2 Compliance with the microbial guideline value . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ## 3 Sampling and analysis . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ## Explanatory note . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . --- Source: https://www.legislation.gov.uk/nisr/2011/10 (the official version) Page: https://openlegislation.uk/water-framework-directive-priority-substances-and-classification-regulations-northern-ireland-2011-revoked Contains public sector information licensed under the Open Government Licence v3.0.
