PART 2Environmental Standards
Environmental standards for river water quality1
Once the Department has, in accordance with paragraphs 1 and 2 of Part I of this Schedule, assigned to a river or any part thereof a Type—
a
specified in column 1 of Table 1 below, it must apply, as applicable, the “high”, “good”, “moderate”, “poor” or “bad” dissolved oxygen standard specified in columns 2, 3, 4, 5 and 6 respectively of that Table to that river or part thereof;
b
specified in column 1 of Table 2 below, it must apply, as applicable, the “high”, “good”, “moderate”, “poor” or “bad” ammonia standard specified in columns 2, 3, 4, 5 and 6 respectively of that Table to that river or part thereof;
c
specified in column 1 of Table 3 below, it must apply, as applicable, the “high”, “good”, “moderate”, “poor” or “bad” biochemical oxygen demand standard specified in columns 2, 3, 4, 5 and 6 respectively of that Table to that river or part thereof.
2
The Department must apply the “high”, “good”, “moderate”, “poor” or “bad” biochemical oxygen demand standard specified in Table 3 below only for the purpose of deciding action to meet the standard for dissolved oxygen.
3
The Department must apply, as applicable, the “high”, “good”, “moderate”, “poor” or “bad” reactive phosphorus standard to that river or part thereof, calculated in accordance with the formula specified in sub paragraph (a)—
a
RP standard = 10^((1.0497 x log10(A)+1.066) x (log10(reference condition RP)- log10(3,500)) + log10(3,500));
b
In relation to the above formula—
“RP standard” is the annual mean concentration of reactive phosphorus in ug/l estimated for the lower class boundary of high, good, moderate and poor ecological status, depending on the value of “A” used;
“A” has the value 0.702 when calculating the standard for high; 0.532 when calculating the standard for good; 0.356 when calculating the standard for moderate; and 0.166 when calculating the standard for poor;
“reference condition RP” = 10^(0.454 (log10alk) – 0.0018 (altitude) + 0.476) and represents the annual mean concentration of reactive phosphorus at near natural conditions. If the predicted value of reference condition RP is <7ug/l, reference condition RP is set to 7ug/l;
“log10alk” means log10(alkalinity), where alkalinity is the concentration of CaCO3 in mg/l. For sites with an alkalinity greater than 250, alkalinity is set to 250. For sites with an alkalinity less than 2, it is set to 2;
“altitude” means the site's altitude above sea level in metres. For sites with an altitude greater than 355 metres, altitude is set to 355 metres.
4
The Department must apply, as applicable, the “high”, “good” “moderate” or “poor” temperature standards specified in columns 2, 3, 4 and 5 respectively of Table 4 below.
5
The Department must apply, as applicable, the “high”, “good”, “moderate” or “poor” acid condition standards specified in columns 2, 3, 4 and 5 of Table 5 to any river or part thereof.
Environmental standards for river flows6
1
Once the Department has, in accordance with paragraph 4 of Part 1 of this Schedule, assigned to a river or part thereof a Type specified in column 1 of Tables 6, 7, 8 or 9 below, it must apply, as applicable, the “high”, “good”, “moderate” or “poor” river flow standards as specified by the boundary values in those Tables to that river or part thereof.
2
The Department may, when assessing the water balance results against the “high”, “good”, “moderate” and “poor” boundary values, take into account the spatial extent of the river flow standard based upon the contiguous length or percentage length of the river water body.
3
The result of this classification shall be used only to determine “high” status in accordance with Part 1 of Schedule 2.
Environmental standards for lake water quality7
The Department must apply, as applicable, the “high”, “good”, “moderate”, “poor” or “bad” dissolved oxygen standard specified in Table 10 below to all lakes or parts of such lakes.
8
The Department must apply the “good” salinity standard specified in Table 11 below to all lakes or parts of such lakes.

Once the Department has, in accordance with paragraph 5 of Part 1 of this Schedule, assigned to a lake or part thereof a geological category, depth category and colour category specified in Tables 5, 6 and 7 in that Part, it must apply, as applicable, the “high”, “good”, “moderate”, “poor” or “bad” total phosphorus standard to that lake or part thereof, calculated in accordance with the formulae specified in columns 1, 2, 3, 4 and 5 respectively of Table 12 below, where in relation to those formulae—
“R” represents the annual mean total phosphorus concentration expected for the lake in the absence of more than very minor phosphorus inputs to the lake resulting from human activities and, where a reliable estimate of ‘C’ is available, shall have the value given by the formula: Antilog10 [1.36 – (0.09 x A) + (0.24 x B)] for non-humic lakes; and Antilog10 [1.62 – (0.09) x A + (0.24 x B)] for humic lakes;
“A” = Log10 of the altitude in metres above mean sea level of the lake;
“B” = Log10 (C÷D);
“C” = the mean alkalinity of the lake in milli-equivalents per litre estimated for the lake;
“D” = the mean depth of the lake in metres;
“H” = 0.755 + (0.012 x C) – (0.001 x D); or 0.7, whichever is larger value; and
“G” = 0.506 + (0.023 x C) – (0.002 x D); or 0.46, whichever is the larger value.

The habitable zone lake surface is dependent on whether the lake is considered to have the geological sub-type “Peat” or “Non-Peat”. The habitable zone lake surface area means the proportion of the reference conditions1 lake surface area from the shore to a depth 5 metres deeper than the depth to which light penetration to the lake bed would be sufficient to enable the growth of rooted plants (macrophytes) or bottom-living algae. In the absence of field data to the contrary, the depth to which light penetration to the lake bed is sufficient to enable the growth of rooted plants (macrophytes) or bottom-living algae may be taken to be 2 metres for lakes with the geological sub-type of “Peat” and 7 metres for “Non-Peat” lakes. The lake habitable zone extends 5m below the level of light penetration to account for impacts on the aphotic habitat. | |||

1 This parameter is the EQS expressed as an annual average value (AA-EQS). Unless otherwise specified, it applies to the total concentration of all isomers. | ||||||||
2 Inland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies. | ||||||||
3 This parameter is the Environmental Quality Standard expressed as a maximum allowable concentration (MAC-EQS). Where the MAC-EQS are marked as “not applicable”, the AA-EQS values are considered protective against short-term pollution peaks in continuous discharges since they are significantly lower than the values derived on the basis of acute toxicity. | ||||||||
4 For the group of priority substances covered by brominated diphenylethers (No 5), the EQS refers to the sum of the concentrations of congener numbers 28, 47, 99, 100, 153 and 154. | ||||||||
5 For cadmium and its compounds (No 6) the EQS values vary dependent upon the hardness of the water as specified in five class categories (class 1: <40mg CaCO3/l, class 2: 40 to <50mg CaCO3/l, class 3: 50 to <100mg CaCO3/l, class 4: 100 to <200mg CaCO3/l and class 5: ≥200mg CaCO3/l). | ||||||||
6 This substance is not a priority substance but one of the other pollutants for which the EQS are identical to those laid down in the legislation that applied prior to 13 January 2009. | ||||||||
7 No indicative parameter is provided for this group of substances. The indicative parameter(s) must be defined through the analytical method. | ||||||||
8 DDT total comprises the sum of the isomers 1,1,1-trichloro-2,2 bis (p-chlorophenyl) ethane (CAS number 50-29-3; EU number 200-024-3); 1,1,1-trichloro-2 (o-chlorophenyl)-2-(p-chlorophenyl) ethane (CAS number 789-02-6; EU number 212-332-5); 1,1-dichloro-2,2 bis (p-chlorophenyl) ethylene (CAS number 72-55-9; EU number 200-784-6); and 1,1-dichloro-2,2 bis (p-chlorophenyl) ethane (CAS number 72-54-8; EU number 200-783-0). | ||||||||
9 There is insufficient information available to set a MAC-EQS for these substances. | ||||||||
10 For the group of priority substances of polyaromatic hydrocarbons (PAH) (No 28), the biota EQS and corresponding AA-EQS in water refer to the concentration of benzo(a)pyrene, on the toxicity of which they are based. Benzo(a)pyrene can be considered as a marker for the other PAHs, hence only benzo(a)pyrene needs to be monitored for comparison with the biota EQS or the corresponding AA-EQS in water. | ||||||||
11 Unless otherwise indicated, the biota EQS relate to fish. An alternative biota taxon, or another matrix, may be monitored instead, as long as the EQS applied provides an equivalent level of protection. For substances numbered 15 (Fluoranthene) and 28 (PAHs), the biota EQS refers to crustaceans and molluscs. For the purpose of assessing chemical status, monitoring of Fluoranthene and PAHs in fish is not appropriate. For substance number 37 (Dioxins and dioxin-like compounds), the biota EQS relates to fish, crustaceans and molluscs, in line with section 5.3 of the Annex to Commission Regulation (EU) No 1259/2011 of 2 December 2011 amending Regulation (EC) No 1881/2006 as regards maximum levels for dioxins, dioxin-like PCBs and non-dioxin-like PCBs in foodstuffs (OJ L 320, 3.12.2011, P.18). | ||||||||
12 These EQS refer to bioavailable concentrations of the substances. | ||||||||
13PCDD: polychlorinated dibenzo-p-dioxins; PCDF: polychlorinated dibenzofurans; PCB-DL: dioxin-like polychlorinated biphenyls; TEQ: toxic equivalents according to the World Health Organisation 2005 Toxic Equivalence Factors. | ||||||||
Application of the standards set out in Table 47 For any given surface water body, applying the AA-EQS means that, for each representative monitoring point within the water body, the arithmetic mean of the concentrations measured at different times during the year does not exceed the standard. 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. Where the Department introduces statistical methods, such methods must apply with rules laid down in accordance with the examination procedure referred to in Article 9(2) of Directive 2008/105/EC. With the exception of cadmium, lead, mercury and nickel (hereinafter “metals”) the standards set out in Table 47 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, or, where specifically indicated, to the bioavailable concentration. 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, dissolved organic carbon or other water quality parameters that affect the bioavailability of metals, the bioavailable concentrations being determined using appropriate bioavailability modelling.

SCHEDULE 2
PART 1Determining Ecological Status of Surface Waters that are not designated Heavily Modified or Artificial
1
The Department must classify the ecological status of surface water bodies that are not designated as heavily modified or artificial in accordance with the following steps:
a
estimate representative values of appropriate indicators of the condition of the relevant biological, physiochemical and hydromorphological quality elements from monitoring or modelling results. The appropriate indicators shall include:
i
indicators of biological and other quality elements expected to be most sensitive to the pressures to which the water body is subject;
ii
the values for physicochemical quality elements at risk of being so altered as to be failing a physicochemical standard ;
iii
the concentrations of those specific pollutants likely to be in the water body in quantities that could cause a failure of a specific pollutant;
iv
the concentrations of those priority substances likely to be in the water body in quantities that could cause failure of chemical status; and
v
the criteria for hydromorphological elements relevant to high status.
b
compare the values of the appropriate indicators estimated from monitoring or modelling with the applicable standards and biological boundary values in Schedule 1 of these Regulations.
c
classify the ecological status of the water body as “high” if the values of all the appropriate indicators of the biological, physicochemical, chemical and hydrological quality elements comply with the highest corresponding standards given in Schedule 1; the assessment of morphological condition carried out in accordance with Part 4 paragraph 1 of this Schedule reflects totally or nearly totally undisturbed conditions; and there is no evidence that a high impact alien species, as identified on the Ecoregion 17 list, has become established and is having an ecological effect on the water body.
d
where the biological quality elements and the general chemical and physiochemical elements and specific pollutants are high and the chemical status is good but the hydromorphological status is less than high, then the overall status of the surface water body is “good”.
e
where a surface water body is not classified as “high” ecological status in accordance with paragraph 1(c), the Department must classify the ecological status of the surface water body according to the lowest classed biological or physicochemical quality element. If the lowest classed quality element is a specific pollutant or other physicochemical quality element, the class assigned shall be no lower than “moderate” ecological status.
2
In this part, “high impact alien species” means a non-native species of plant or animal that has a detrimental effect on the aquatic ecology or environment.
PART 2Determining Chemical Status of Surface Waters
1
The Department must classify the chemical status of surface water bodies in accordance with the following steps:
a
estimate from monitoring or modelling results the concentrations in the surface water body of appropriate priority substances listed in Schedule 1 of these Regulations. The appropriate substances shall include those likely to be in the surface water body in quantities that could cause a failure of the corresponding environmental quality standard.
b
compare the values of the appropriate substances estimated from monitoring or modelling with the applicable standards in Schedule 1.
c
classify the chemical status of the surface water body as good unless the standard for one or more priority substances is failed. If one or more is failed, classify as failing to achieve good chemical status.
PART 3Determining Ecological Potential of Heavily Modified and Artificial Water Bodies
1
The Department must classify a surface water body designated as heavily modified or artificial as—
a
“good ecological potential” if the following conditions are met:
i
all applicable mitigation measures have been taken; and
ii
the values of all the indicators of the quality elements not sensitive to hydromorphological pressures related to the heavily modified or artificial water body designation, including biology, specific pollutants and other physicochemical quality elements achieve the standards for “high” or “good”.
b
“moderate ecological potential” if the following conditions are met:
i
not all applicable mitigation measures have been taken and the values of one or more of the indicators of the quality elements not sensitive to hydromorphological pressures directly related to the heavily modified or artificial water body designation, including biology, specific pollutants and other physicochemical quality elements achieve the standards for “high”, “good” or “moderate”; or
ii
all applicable mitigation measures have been taken and the values of one or more of the indicators of the quality elements not sensitive to hydromorphological pressures directly related to the heavily modified or artificial water body designation, including biology, specific pollutants and other physicochemical quality elements achieve the standards for “moderate”.
c
“poor ecological potential” if the values of one or more of the indicators of the biological quality elements not sensitive to hydromorphological pressures directly related to the heavily modified or artificial water body designation achieve the standards for “poor”.
d
“bad ecological potential” if the values of one or more of the indicators of biological quality elements not sensitive to hydromorphological pressures directly related to the heavily modified or artificial water body designation achieve the standards for “bad”.
2
In order to determine how to classify surface water bodies designated as heavily modified or artificial in accordance with paragraph 1, the Department must —
a
determine whether or not all practicable mitigation has been taken to improve the modified or artificial hydromorphological characteristics of the surface water body other than that which would have a significant adverse impact on:
i
the use served by the modified or artificial characteristics; or
ii
the wider environment.
b
estimate representative values of indicators of the condition of the relevant biological and physicochemical quality elements from monitoring or modelling results. The indicators shall include:
i
indicators of the biological quality elements which are not sensitive to the artificial or heavily modified characteristics of the water body;
ii
the concentrations of those specific pollutants likely to be in the surface water body in quantities that could cause a failure of a specific pollutant standard; and
iii
the values for those other physicochemical quality elements at risk of being so altered as to be failing a physicochemical standard.
c
compare the values of the indicators estimated from monitoring or modelling with the applicable standards in Schedule 1 of these Regulations.
3
When determining whether all practicable mitigation has been taken, mitigation measures may be excluded which would contribute only a very minor improvement in the ecology of the water body.
PART 4Determining High Status for Morphological Elements
1
The Department must monitor morphological conditions within relevant water bodies.
a
Once the Department has, in accordance with paragraph 3 of Part 1 of Schedule 1, assigned a type to a river or part thereof, the Department must consider both direct and indirect pressures on the physical character of rivers at local scale, water body scale and catchment scale. The physical character of a river includes the condition of the channel bed, banks and riparian zone, channel pattern and river continuity. Classification shall be assigned according to the ecological quality ratio in the River Hyrdromorphology Assessment Technique specified in Table 1 of this Part.
b
Once the Department has in accordance with paragraphs 7 of Part 1 of Schedule 1 assigned a type to a lake, the Department must consider both direct and indirect pressures on the physical character of lakes in the shore zone and open water. Morphological Condition Limits are used to represent thresholds of alteration in morphological conditions beyond which conditions could be altered in ways that could result in deterioration in status. A Morphological Condition Limit of 5% is the boundary between High Ecological Status and Good Ecological Status and a Morphological Condition Limit of 15% is the boundary between Good Ecological Status and Moderate Ecological Status.
c
To assess the morphological condition of transitional and coastal water bodies, the Department must consider both direct and indirect pressures on the physical character of transitional and coastal waters at local scale, water body scale and catchment scale.
2
High Status morphological condition must not be assigned to
a
Any water body that has been identified as being at risk of failing to achieve good ecological status due to the extent of morphological pressures; or
b
Any artificial or heavily modified water body.
Boundary values for the River Hydromorphology Assessment Technique | |
|---|---|
Ecological quality ratio | |
High | >=0.8 |
Good | 0.6 - < 0.8 |
Moderate | 0.4 - <0.6 |
Poor | 0.2 - <0.4 |
Bad | <0.2 |
PART 5Determining Overall Status of Surface Water Bodies
1
The Department must determine the overall status of a surface water body, other than those designated as heavily modified or artificial, by combining the classification of ecological status and chemical status in one of the following and alternative ways:
a
where the ecological and hydromorphological status of a surface water body is high and the chemical status of the surface water body is good, then the overall status of the surface water body is “high”.
b
where the biological quality elements and the general chemical and physiochemical elements and specific pollutants are high and the chemical status is good but the hydromorphological status is less than high, then the overall status of the surface water body is “good”
c
where the ecological status is good and the chemical status is good, then the overall status is “good”.
d
where the ecological status is high, good or moderate, and the chemical status is failing to achieve good, then the overall status is “moderate”.
e
where the ecological status is moderate and irrespective of chemical status, then the overall status is “moderate”.
f
where the ecological status is poor or bad and irrespective of the chemical status, the overall status shall be the same classification as the ecological status, that is “poor” or “bad”.
SCHEDULE 3Determining Quantitative status of Groundwater
1
1
The Department must determine the quantitative status of a body of groundwater as follows—
a
by determining whether or not one or more of the indicators in Column 1 of Table 1 are applicable to the body of groundwater; and
b
if any of those indicators are applicable, by carrying out appropriate investigations to determine whether or not the criteria in Column 2 of Table 1 corresponding to the applicable indicator or indicators for poor quantitative status are satisfied.
2
The body of groundwater must be classified as—
a
“good groundwater quantitative status” where—
i
none of the indicators set out in Column 1 of Table 1 are applicable, or
ii
one or more of those indicators are applicable but none of the corresponding criteria for poor groundwater status set out in Column 2 of Table 1 are satisfied; and
b
in any other case as “poor groundwater quantitative status”.
Column 1 | Column 2 |
|---|---|
Saline or other intrusions into a groundwater body: a) Failure of a threshold value i.e. electrical conductivity for groundwater as derived in accordance with the Groundwater Regulations (Northern Ireland) 2009; or b) Other indications of intrusions of poor quality water into the body of groundwater (Note: “intrusion” is interpreted to be intrusion of poor quality water into a groundwater body from another water body, rather than the movement of a plume of poor quality water within the body). | i) Significant and sustained upward trend in electrical conductivity indicating saline intrusion; ii) Significant and sustained upward trend in the concentration of other indicators of intrusion; iii) Existing evidence that a point of abstraction has been rendered unsuitable for use without prior treatment as a result of an intrusion. |
Surface water: a) Flow conditions in an associated surface water body are unsatisfactory, and there is reason to suspect that groundwater abstraction impacts (on the surface water body) are a significant component of the failure to achieve flow standards. (Note: Flow conditions are considered unsatisfactory if they are failing to meet the appropriate WFD flow standards and in doing so, preventing the surface water body maintaining of achieving its target status class). | i) Flow conditions are preventing the surface water body maintaining or achieving the target status class and the reduction in river flow in the surface water body concerned (resulting solely from groundwater abstraction) represents ≥50% of the value of the allowable abstraction (based on the flow standards). |
Groundwater Dependant Terrestrial Ecosystems (GWDTE): a) Indications of damage to a GWDTE caused by insufficient water availability identified through the departure from predefined environmental supporting conditions, including flow and groundwater level (or chemistry) which are required to maintain dependent communities in a favourable state. | i) A significant proportion of the departure from the predefined environmental supporting conditions can be attributed to anthropogenic quantitative pressures in the groundwater body, affecting groundwater availability to the GWDTE. |
Water balance: a) Indications that the total annual volume of groundwater being abstracted from the groundwater body exceeds the long term annual average rate of recharge to the groundwater body (taking in to account an allowance where relevant for dependent ecosystems). | i) The annual average volume of groundwater abstracted from the groundwater body represents more than the long-term annual average rate of recharge to the groundwater body and there are sustained trends of long term falling groundwater levels within the groundwater body. |
