CAP’s Geological framework supporting its WSP Starting Point Council Directive 98/83/EC of 3 November 1998 on the quality of water intended for human consumption Objective: «Protect human health from the adverse effects of any contamination of water intended for human consumption by ensuring that it is wholesome and clean»

CAP’s Geological framework supporting its WSP Review of Drinking Water Directive • Revision of technical annexes: Annexes II and III • New Annex II provides an option to perform the drinking water monitoring in around 100,000 water supply zones in Europe in a more flexible way, a risk assessment is performed ensuring full protection of public health

CAP’s Geological framework supporting its WSP Role of Supplier • Moving straight ahead to cope with the following challenges. Improving water quality for protection of: • Human health (DWD) • Environment (WFD, GW Resources?) It’s time to create a platform linking DWD and WFD!! Gathering mandatory (legal measures) and voluntary approaches (stakeholders involvement, broadcasting information, users communitiy, etc.) aiming at better protecting GW resources and HH

CAP’s Geological framework supporting its WSP Multidisciplinary Approach: Role of WSP • A new deal is coming…… Under the aegis of WSP (WHO, 2004) Multidisciplinary and multitasking Tool Knowledge of Hydrogeological/ Risk Assessment Hydrochemical Processes Risk Management Quantity/Quality Analysis Monitoring Programs PoMs Water Safety Plan

CAP’s Geological framework supporting its WSP Knowing the whole system Geological units «Sound management and Monza operational system help Milano prevent, not simply react to, the contamination of drinking water» (O’Connor, 2002) Working at basin scale «Know your system» from ground water source to consumer (source- to-tap directive) The more you know… the better you protect and manage

CAP’s Geological framework supporting its WSP Chemistry & pollutants Too many substances… few of Chloride them monitored Nitrate Working at PCE basin scale Note: Current discrepancy between the DWD and derivation of Environmental Quality Standards (EQS) under the Priority Substances Directive 1 4

CAP’s Geological framework supporting its WSP Quality: ionic ratios Recharge zone Recharge zone Many basic issues: do not sweep them under the carpet Quite older Working at basin scale Mostly younger • Ageing of GW & recharge rates • Degree of vulnerability • Connections SW - GW • Catchment zones and WHPAs

CAP’s Geological framework supporting its WSP Quality: isotopic profile of aquifers δ Deuterium Tritium (T.U.) Higher values Younger water Working at basin scale Higher values Higher values δ Oxigen-18 δ Carbon-13 16

CAP’s Geological framework supporting its WSP Monitoring – DWD point of view • «Member States shall take all measures necessary to ensure that regular monitoring of the quality of water intended for human consumption is carried out… • In order to check that the water available to consumers meets the requirements of DWD and in particular the parametric values set in accordance with Article 5 • Samples should be taken so that they are representative of the quality of the water consumed throughout the year»

CAP’s Geological framework supporting its WSP Monitoring – WSP point of view • During the phase of implementation, it’s important to avoid complacency, encouraging a culture of vigilance and continuous improvement • Challenge: find a method remaining objective and ultimately useful in providing a point of reference from which to make further improvements This falls into two main areas: • Output assessment. Analysing institutional, operational, financial and policy outcomes • Input assessment. Report on the completeness and adequacy of actions required to implement a WSP IWA and WHO produced the WSP Quality Assurance Tool
