MONITORAĠĠ
PARTI A
L-għanijiet ġenerali u l-programmi ta’ monitoraġġ għall-ilma maħsub għall-konsum mill-bniedem
1. Il-programmi ta’ monitoraġġ stabbiliti skont l-Artikolu 13(2) għall-ilma maħsub għall-konsum mill-bniedem għandhom:
(a)
jivverifikaw li l-miżuri fis-seħħ għall-kontroll tar-riskji għas-saħħa tal-bniedem tul il-katina tal-provvista tal-ilma miż-żona tal-astrazzjoni permezz tat-trattament u l-ħżin sad-distribuzzjoni qed jaħdmu b’mod effettiv u li l-ilma maħsub għall-konsum mill-bniedem fil-punt tal-konformità jkun tajjeb u nadif;
(b)
jagħtu informazzjoni dwar il-kwalità tal-ilma fornut għall-konsum mill-bniedem biex juru li l-obbligi stipulati fl-Artikolu 4 u l-valuri parametriċi stabbiliti skont l-Artikolu 5 huma ssodisfati;
(c)
jidentifikaw l-aktar mezzi xierqa biex jitnaqqas ir-riskju għas-saħħa tal-bniedem.
2. Il-programmi ta’ monitoraġġ stabbiliti skont l-Artikolu 13(2) għandhom jinkludu wieħed minn dawn li ġejjin jew taħlita tagħhom:
(a)
ġbir u analiżi ta’ kampjuni diskreti tal-ilma;
(b)
kejl irreġistrat permezz ta’ proċess kontinwu ta’ monitoraġġ.
Barra minn hekk, il-programmi ta’ monitoraġġ jistgħu jikkonsistu minn:
(a)
spezzjonijiet tar-reġistrazzjonijiet tal-funzjonalità u l-manteniment tal-istatus tal-apparat;
(b)
spezzjonijiet taż-żona tal-astrazzjoni, u tal-infrastruttura tad-distribuzzjoni, it-trattament u l-ħżin, mingħajr preġudizzju għar-rekwiżiti ta’ monitoraġġ previsti fil-punt (c) tal-ewwel subparagrafu tal-Artikolu 8(2) u l-punt (b) tal-ewwel subparagrafu tal-Artikolu 10(1).
3. Il-programmi ta’ monitoraġġ għandhom jinkludu wkoll programm ta’ monitoraġġ operazzjonali li jipprovdi għarfien immedjat dwar il-prestazzjoni operattiva u dwar problemi relatati mal-kwalità tal-ilma u li jippermetti li tittieħed azzjoni korrettiva rapida ppjanata minn qabel. Tali programmi ta’ monitoraġġ operazzjonali għandhom ikunu speċifiċi għall-provvista, filwaqt li jqisu l-eżiti tal-identifikazzjoni tal-perikli u l-avvenimenti perikolużi u l-valutazzjoni tar-riskju tas-sistema tal-provvista, u għandhom ikunu maħsubin biex jikkonfermaw l-effettività tal-miżuri kollha ta’ kontroll b’rabta mal-astrazzjoni, it-trattament, id-distribuzzjoni u l-ħżin.
Il-programm ta’ monitoraġġ operazzjonali għandu jinkludi l-monitoraġġ tal-parametru tat-‘turbidità’ fl-impjant tal-provvista tal-ilma sabiex jikkontrolla b’mod regolari l-effikaċja tat-tneħħija b’mod fiżiku permezz ta’ proċessi ta’ filtrazzjoni, f’konformità mal-valuri ta’ referenza u l-frekwenzi indikati fit-tabella li ġejja (mhux applikabbli għas-sorsi ta’ ilma ta’ taħt l-art fejn it-turbidità hija kkawżata mill-ħadid u l-manganiż):

|
Dan il-parametru għandu jitkejjel jekk il-valutazzjoni tar-riskju tindika li huwa xieraq li dan isir. Jekk jinsab f’ilma mhux trattat f’konċentrazzjonijiet ta’ > 50 PFU/100 ml, għandu jiġi analizzat wara l-passi tas-sekwenza ta’ trattament sabiex tiġi determinata t-tneħħija (f’log) permezz tal-ostakli fis-seħħ u biex jiġi vvalutat jekk ir-riskju ta’ tifqigħa ta’ virus patoġeniċi huwiex suffiċjentement taħt kontroll.
|
4. L-Istati Membri għandhom jiżguraw li l-programmi ta’ monitoraġġ jiġu riveduti fuq bażi kontinwa u aġġornati jew ikkonfermati tal-anqas kull sitt snin.
Parti B
Parametri u frekwenzi ta’ kampjunar
Grupp A
Il-parametri li ġejjin (il-Grupp A) għandhom jiġu ssorveljati skont il-frekwenzi ta’ monitoraġġ kif stipulat fit-Tabella 1 tal-punt 2:
(a)
Escherichia coli (E. Coli), enterokokki intestinali, batterji koliformi, l-għadd tal-kolonji f’temperatura ta’ 22 °C, kulur, turbidità, togħma, riħa, pH u konduttività;
(b)
parametri oħra identifikati bħala rilevanti fil-programm ta’ monitoraġġ, skont l-Artikolu 5(3) u, fejn rilevanti, permezz ta’ valutazzjoni tar-riskju tas-sistema tal-provvista kif stipulat fl-Artikolu 9 u fil-Parti C tal-Anness.
F’ċirkostanzi speċifiċi, il-parametri li ġejjin għandhom jiżdiedu mal-parametri tal-Grupp A:
(a)
ammonju u nitrit, jekk tintuża l-kloraminazzjoni;
(b)
aluminju u ħadid, jekk jintużaw bħala sustanzi kimiċi għat-trattament tal-ilma.
Escherichia coli (E. coli) u enterokokki intestinali huma meqjusa bħala “parametri ewlenin” u l-frekwenzi fil-monitoraġġ tagħhomma għandhomx ikunu s-suġġett ta’ tnaqqis minħabba valutazzjoni tar-riskju tas-sistema tal-provvista skont l-Artikolu 9 u l-Parti C ta’ dan l-Anness. Dawn għandhom dejjem ikunu mmonitorjati tal-inqas skont il-frekwenzi stabbiliti fit-Tabella 1 tal-punt 2.
Grupp B
Sabiex tiġi determinata l-konformità mal-valuri parametriċi kollha stipulati f’din id-Direttiva, kull parametru ieħor mhux analizzat taħt il-Grupp A u stabbilit f’konformità mal-Artikolu 5, ħlief għall-parametri fil-Parti D tal-Anness I, għandhom jiġu mmonitorjati tal-anqas skont il-frekwenzi stipulati fit-Tabella 1 tal-punt 2, sakemm ma tiġix determinata frekwenza ta’ kampjunar differenti abbażi ta’ valutazzjoni tar-riskju tas-sistema tal-provvista mwettqa f’konformità mal-Artikolu 9 u l-Parti C ta’ dan l-Anness.

Nota 1: Żona ta’ forniment hija żona ġeografika identifikata li tforni ilma maħsub għall-konsum mill-bniedem minn sors wieħed jew aktar u li l-kwalità tal-ilma tagħha tista’ titqies li hi bejn wieħed u ieħor l-istess.
Nota 2: Il-volumi huma kkalkulati bħala medji għal sena kalendarja. Jista’ jintuża l-għadd ta’ abitanti f’żona ta’ forniment minflok il-volum ta’ ilma biex tiġi ddeterminata l-frekwenza minima, meta wieħed jassumi l-konsum ta’ ilma bħala 200 l/(ġurnata*capita).
Nota 3: Il-frekwenza indikata hija kkalkulata kif ġej: eż. 4 300 m3/ġurnata = 16-il kampjun għall-parametri tal-Grupp A (erbgħa għall-ewwel 1000 m3/ġurnata + 12 għat-3 300 m3/ġurnata addizzjonali).
Nota 4: Għall-fornituri tal-ilma, meta ma tkunx ingħatat eżenzjoni skont il-punt (b) tal-Artikolu 3(3), l-Istati Membri għandhom jistabbilixxu l-frekwenza minima tal-kampjunar għall-parametri tal-Gruppi A u B, dment li l-parametri ewlenin jiġu monitorjati mill-inqas darba fis-sena.
Nota 5: L-Istati Membri jistgħu jnaqqsu l-frekwenza tal-kampjunar dment li l-parametri kollha stabbiliti f’konformità mal-artikolu 5 jiġu mmonitorjati mill-inqas darba kull sitt snin u jiġu mmonitorjati f’każijiet fejn jiġi integrat sors ġdid tal-ilma fis-sistema tal-provvista tal-ilma jew isir tibdil f’dik is-sistema, u b’riżultat ta’ dan hu mistenni impatt potenzjalment negattiv fuq il-kwalità tal-ilma.

PARTI C
Valutazzjoni tar-riskju u ġestjoni tar-riskju tas-sistema tal-provvista
1. Abbażi tal-eżitu tal-valutazzjoni tar-riskju tas-sistema tal-provvista kif imsemmi fl-Artikolu 9, il-lista tal-parametri kkunsidrati fil-monitoraġġ għandha tiġi estiża u l-frekwenzi tal-kampjunar stabbiliti fil-Parti B għandhom jiżdiedu, fejn hija ssodisfata kwalunkwe waħda minn dawn il-kundizzjonijiet li ġejjin:
(a)
il-lista tal-parametri jew tal-frekwenzi stipulata f’dan l-Anness mhijiex biżżejjed biex jiġu ssodisfati l-obbligi imposti skont l-Artikolu 13(1);
(b)
huwa meħtieġ monitoraġġ addizzjonali għall-finijiet tal-Artikolu 13(5);
(c)
huwa meħtieġ li jingħataw l-assigurazzjonijiet stipulati fil-punt (a) tal-punt 1 tal-Parti A;
(d)
huwa meħtieġ li l-frekwenzi tal-kampjunar jiżdiedu skont il-punt (a) tal-ewwel subparagrafu tal-Artikolu 8(4).
2. Bħala riżultat ta’ valutazzjoni tar-riskju tas-sistema tal-provvista, il-lista tal-parametri kkunsidrati fil-monitoraġġ u l-frekwenzi tal-kampjunar stipulati fil-Parti B jistgħu jitnaqqsu dment li jiġu ssodisfati il-kundizzjonijiet kollha li ġejjin:
(a)
il-post u l-frekwenza tal-kampjunar huma ddeterminati b’rabta mal-oriġini tal-parametri, kif ukoll mal-varjabbiltà ta’ u x-xejra fuq termini twal dwar il-konċentrazzjoni tagħhom, b’kont meħud tal-Artikolu 6;
(b)
fir-rigward tat-tnaqqis fil-frekwenza minima tal-kampjunar ta’ parametru, ir-riżultati miksuba mill-kampjuni miġbura f’intervalli regolari fuq perijodu ta’ mill-anqas tliet snin, minn punti ta’ kampjunar li jirrappreżentaw iż-żona kollha ta’ forniment, huma kollha anqas minn 60 % tal-valur parametriku;
(c)
fir-rigward tat-tneħħija ta’ parametru mil-lista ta’ parametri li għandhom jiġu mmonitorjati, ir-riżultati miksuba mill-kampjuni miġbura f’intervalli regolari fuq perijodu ta’ mill-anqas tliet snin, minn punti ta’ kampjunar li jirrappreżentaw iż-żona kollha ta’ forniment, huma kollha anqas minn 30 % tal-valur parametriku;
(d)
fir-rigward tat-tneħħija ta’ parametru mil-lista ta’ parametri li għandhom jiġu mmonitorjati, id-deċiżjoni hi bbażata fuq l-eżitu tal-valutazzjoni tar-riskju li tikkunsidra r-riżultati tal-monitoraġġ tas-sorsi tal-ilma maħsub għall-konsum mill-bniedem u li jikkonfermaw li s-saħħa tal-bniedem hija protetta minn kull effett ħażin ta’ kontaminazzjoni ta’ ilma maħsub għall-konsum mill-bniedem, kif stipulat fl-Artikolu 1;
(e)
fir-rigward tat-tnaqqis fil-frekwenza tal-kampjunar ta’ parametru jew it-tneħħija ta’ parametru mil-lista ta’ parametri li għandhom jiġu mmonitorjati, il-valutazzjoni tar-riskju tikkonferma li ma jista’ jiġi antiċipat l-ebda fattur li jista’ jikkawża deterjorazzjoni tal-kwalità tal-ilma maħsub għall-konsum mill-bniedem.
Meta r-riżultati tal-monitoraġġ, li juru li l-kondizzjonijiet stipulati fil-punti (2)(b) sa (2)(e) ikunu ġew issodisfati, ikunu diġà disponibbli mit-12 ta’ Jannar 2021, dawk ir-riżultati tal-monitoraġġ jistgħu, minn dik id-data, jintużaw biex il-monitoraġġ jiġi adattat skont il-valutazzjoni tar-riskju tas-sistema tal-provvista.
Fejn ikunu diġà ġew implimentati aġġustamenti għall-monitoraġġ b’segwitu għall-valutazzjoni tar-riskju tas-sistema tal-provvista skont, fost l-oħrajn, il-Parti C tal-Anness II tad-Direttiva 98/83/KE, l-Istati Membri jistgħu jipprevedu l-possibbiltà li tiġi kkonfermata l-validità tagħhom mingħajr ma jkun rikjest monitoraġġ skont il-punti 2(b) u 2(c) tul perijodu ulterjuri ta’ mill-inqas tliet snin minn punti rappreżentattivi taż-żona kollha tal-provvista.
PARTI D
Il-metodi u l-punti tal-kampjunar
1. Il-punti tal-kampjunar għandhom jintgħażlu b’mod li jassiguraw il-konformità mal- Artikolu 6(1). F’każ ta’ netwerk ta’ distribuzzjoni, Stat Membru jista’ jieħu kampjuni fiż-żona ta’ forniment jew mix-xogħlijiet ta’ trattament għal parametri partikolari jekk ikun jista’ jintwera li mhux ser jkun hemm l-ebda bidla negattiva għall-valur imkejjel tal-parametri kkonċernati. Sa fejn huwa possibbli, l-għadd ta’ kampjuni għandu jitqassam ugwalment kemm fil-ħin kif ukoll fil-post.
2. Il-kampjunar fil-punt ta’ konformità għandu jissodisfa dawn ir-rekwiżiti:
(a)
il-kampjuni tal-konformità għal ċerti parametri kimiċi, b’mod partikolari r-ram, iċ-ċomb, u n-nikil, għandhom jittieħdu mill-viti tal-konsumaturi mingħajr ifflaxxjar minn qabel. Għandu jittieħed kampjun aleatorju b’volum ta’ litru matul il-ġurnata. Bħala alternattiva, l-Istati Membri jistgħu jużaw metodi ta’ żmien fiss ta’ staġnar li jirriflettu s-sitwazzjonijiet nazzjonali tagħhom, bħall-konsum medju ta’ kull ġimgħa mill-konsumatur, sakemm fil-livell taż-żona ta’ forniment, dan ma jirriżultax f’każijiet anqas ta’ nuqqas ta’ konformità minn meta jintuża l-metodu aleatorju ta’ matul il-ġurnata;
(b)
il-kampjuni ta’ konformità għall-parametri mikrobijoloġiċi fil-punt ta’ konformità għandhom jittieħdu u jiġu mmaniġġati skont EN ISO 19458, l-iskop B tal-kampjunar.
3. Il-kampjuni tal-Legionella f’sistemi ta’ distribuzzjoni domestika għandhom jittieħdu f’punti ta’ riskju għall-proliferazzjoni tal-Legionella, punti rappreżentattivi għall-esponiment sistematiku għal-Legionella, jew it-tnejn. L-Istati Membri għandhom jistabbilixxu linji gwida għal metodi ta’ kampjunar għal-Legionella.
4. Il-kampjunar fin-netwerk ta’ distribuzzjoni, bl-eċċezzjoni tal-kampjunar fil-viti tal-konsumaturi, għandu jkun skont ISO 5667-5. Għall-parametri mikrobijoloġiċi, il-kampjuni fin-netwerk ta’ distribuzzjoni għandhom jittieħdu u jiġu mmaniġġati skont EN ISO 19458, l-iskop A tal-kampjunar.

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 can 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. 4 300 m3/d = 16 samples for Group A parameters (four for the first 1 000 m3/d + 12 for additional 3 300 m3/d).
|
|
Note 4:
|
For water suppliers, where an exemption has not been granted under point (b) of Article 3(3), Member States 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.

Member States may reduce the sampling frequency, provided that all parameters set in accordance with Article 5 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.

|
|
1.
|
Based on the outcome of the risk assessment of the supply system as referred to in Article 9, the list of parameters considered in the monitoring shall be extended and the sampling frequencies set out in Part B increased where any of the following conditions is fulfilled:
|
(a)
|
the list of parameters or frequencies set out in this Annex is not sufficient to fulfil the obligations imposed under Article 13(1);
|
|
(b)
|
additional monitoring is required for the purposes of Article 13(5);
|
|
(c)
|
it is necessary to provide the assurances set out in point (a) of point 1 of Part A;
|
|
(d)
|
increasing the sampling frequencies is necessary pursuant to point (a) of the first subparagraph of Article 8(4).
|
|
|
|
2. As a result of a risk assessment of the supply system, the list of parameters considered in the …
|
|
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 Article 6;
|
|
(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 to 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 Article 1;
|
|
(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 can be reasonably anticipated is likely to cause deterioration of the quality of the water intended for human consumption.
|
Where monitoring results, demonstrating that the conditions set out in points (2)(b) to (2)(e) are met, are already available by 12 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, Member States may provide for the possibility to confirm their validity without requiring monitoring in accordance with point 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 sampling points
|
|
1. Sampling points shall be determined so as to ensure compliance with Article 6(1). In the case of …
|
|
1.
|
Sampling points shall be determined so as to ensure compliance with Article 6(1). In the case of a distribution network, a Member State 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) compliance …
|
|
2.
|
Sampling at the point of compliance shall meet the following requirements:
|
(a)
|
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 is to be taken. As an alternative, Member States may use fixed stagnation time methods that better reflect their 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)
|
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. Samples for Legionella in domestic distribution systems shall be taken at risk points for …
|
|
3.
|
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. Member States shall establish guidelines for sampling methods for Legionella.
|
|
|
4. Sampling in the distribution network, with the exception of sampling at the consumers’ tap …
|
|
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.
