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 CaCO 3 /l, class 2: 40 to <50mg CaCO 3 /l, class 3: 50 to <100mg CaCO 3 /l, class 4: 100 to <200mg CaCO 3 /l and class 5: ≥200mg CaCO 3 /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.

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

(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., High,Blue, Good,Green, Moderate,Yellow, Poor,Orange, Bad,Red, Good and above,Equal green and light grey stripes,Equal green and dark grey stripes, Moderate,Equal yellow and light grey stripes,Equal yellow and dark grey stripes, Poor,Equal orange and light grey stripes,Equal orange and dark grey stripes, Bad,Equal red and light grey stripes,Equal red and dark grey stripes, Good,Blue, Failing to achieve good,Red, Good,Green, Poor,Red, Good,Green, Poor,Red, Temperature,◦C,A discharge affecting shellfish waters must not cause the temperature of the water to exceed by more than 2◦C the temperature of the waters not so affected., pH,,pH values will not reach levels outside of the range established so as to ensure the functioning of the ecosystem and the achievement of the values specified for the biological quality elements under Good Ecological Status, Silver,Annual mean (AA-EQS) (µg/l),0.5, Maximum allowable concentration (MAC-EQS) (µg/l),1, Salinity,Practical Salinity Units (PSU),≤ A discharge affecting shellfish waters must not cause their salinity to exceed by more than 10% the salinity of waters not so affected., Salinity,PSU,12-38, Escherichia coli (E.coli),cfu/100ml,≤230 in the shellfish flesh and intervalvular liquid,ISO16649 part 3 or equivalent,Quarterly,
