Relevant Polllutants - Background nIreland largely enjoys relative clean waters nDue, at least in part, to its less industrialised history nTransboundary inputs are relatively insignificant nThe usage of chemicals throughout all sectors of society has become increasingly widespread during the past century

River Basin Districts 4 Internal RBDs South-Eastern South-Western Western Eastern 3 Cross-border RBDs North-Western Neagh-Bann Shannon 1 in RBD Northern Ireland North-Eastern

Water Framework Directive nSurveillance Monitoring Programme: nPriority list pollutants which are discharged….. nAnnex X nMonthly sampling nOther Pollutants discharged in significant quantities…… nAnnex VIII: 1-10 n3-monthly sampling

Monitoring Plan nSelect Relevant Pollutants nChoose surveillance monitoring programme sites nCommence Monitoring programme 2007 nAnnex IX and X nRelevant pollutant list

Relevant Pollutant Selection 1.Top-down Approach Consider all substances potentially introduced to the environment in Ireland Prioritise based on Knowledge of usage Available monitoring data 2. Bottom-up Approach Consider known water quality impacts Little information available on organics effects 3. Check selected list by a screening survey

Candidate list of relevant pollutants Selection of compounds: WFD Annex VIII – “universe of chemicals” as starting point WFD Annex X and Annex IX compounds included automatically Pollutant lists considered: 76/464/EC List II candidate substances UNEP POPs OSPAR EPER Register Dangerous Substances tracking project Locally Relevant Pesticides Aquatic environment control products Endocrine disrupting products Total number of substances/groups161

Screening Programme nWide range of Parameters to be measured n12 Month programme 41 Priority Action Substances 161 Relevant Pollutants 227 parameters reported (including sums) nReview Relevant Pollutants list after six months nContinue with shortened list for remaining six months nCompare results with working EQS values

Screening Programme Sites nMonitoring programme - 23 sites 17 Surface water sites 4 Groundwater sites 1 site at WWTP - Ringsend, Dublin 1 site at Landfill - Ballyeally, Dublin nWater samples taken monthly at each site. nOne sediment and one biota sample taken at the 17 surface water sites

Screening Programme Assessment Because EQS are not finalised at this stage Results were compared with Limit of Detection (LOD) First phase – 43 parameters dropped after 6 months Not found Not appropriate for water column work Detection limit too high to be useful (LOD>>EQS) Continued with new pesticides for 6 months

Results of Screening Programme - Provisional Surface Waters (17 sites) Test substance for relevance: Means compiled for each site Test for any mean > LOD 56 compounds found Metals18 VOC13 Organics8 Pesticides13 PAH2 Inorganic2

Results of Screening Survey - Provisional Ground Waters (4 sites) Test substance for relevance: Means compiled for each site Test for any mean > LOD 31 compounds found Inorganic2 Metals13 Organics7 Pesticides4 PAH1 VOC4

Environmental Quality Standards Priority Substances: Commission Proposal July 2006 Annex I Part A: 33 parameters Part B: 8 parameters Relevant Pollutants: No final decision Working group on EQS Adopt EQS used in screening work? Look for common applications in other MS

Future Challenges Analytical resources Cost Set-up time Development of EQS for Relevant Pollutant list EQS levels will define the monitoring activity Some toxicologically derived EQS unattainable by existing monitoring techniques Some discussion on equipment level is desirable to ensure proper investment of resources eg Metals - ICPMS Organics?
