  1. GENESIS recommendations Matteo Balderacchi, Marco Trevisan, Elena Preda, BjørnKløve

  2. Problem formulation • to protect the environment as a whole, and human health in particular STATUS • detrimental concentrations of harmful pollutants in groundwater must be avoided, prevented or reduced POLLUTION policy-makers have set criteria for protecting water and life, balancing between economic and ecological consequences, while scientists have to support policy

  3. Role of GENESIS • STATUS • To Give advice on INDICATORS • POLLUTION • To provide suggestion about some POLLUTANT

  4. Effects • Effects can be characterised by several endpoints related to different organisms (human and non-human), according to the objective of the assessment • Selection of the threshold values is mainly a political issue

  5. Fait G., ter Horst M., Boesten J., Li W., Tao C. 2011, Developing Groundwater scenarios for northern China and comparison of their vulnerability with FOCUS groundwater scenarios. XIV Pesticide Chemistry Symposium, Piacenza

  6. Groundwater assessment- indicators Existing initiatives for development of “groundwater ecosystem assessment scheme” similar to those for surface water bodies according with WFD (Griebler et al.2010). It considers: Basic microbial parameters (bact.abundance, b.biomass,coliforms) microbial community (biomass, composition and structure, physiological status-activity) groundwater fauna (composition, abundance, diversity) related to specific physico-chemical parameters (pH, temp, DO, DOC/TOC, nutrients, ions, heavy metals,…)

  7. Indicators- Genesis framework Assessment of coupled systems- groundwater and dependent ecosystems Designing of the most suitable sets/packages for specific GDEs considering: ecosystem characteristics, scale, ecosystems sensitivity/ vulnerability, indicator sensitivity, data availability, intended purpose, DPSIR model (Stress indicators, State and Impact indicators, Response indicators). It includes GW indicators relevant for GDEs

  8. Proposed indicators package • GW dependency indicators • Natural isotopes and tracers- indicators; Water balance / Water temperature/ Electric conductivity • GW indicators • Total abstraction of groundwater/ GW recharge ; Total abstraction of GW/ exploitable GW resources; GW as a % of total drinking water on a catchment level; GW vulnerability indicator / GW quality indicator • Biological indicators • Red-listed spring dependent species/ Proportion of spring-dependent; macroinvertebrates/ Spring specialist species; Microbial communities / Species richness : macroinvertebrates, fishes • Land use characteristics • % agrosystems, % forests, % socio-economic systems (e.g. rural, urban, settlements) from catchment surface • Conservation value/status • No.protected areas/ catchment surface (e.g. Natura 2000 sites) / % protected areas from total

  9. Risk assessment for Emerging pollutants Review of Ranking procedure for giving priority to emerging pollutants.

  10. Diffuse contamination

  11. Point contamination

  12. Other pressures

  13. Genesis Raccomandations • Household and Industry are not deeply considered in current Groundwater directive • Identifying science based thresholds • The series of Chloroethylenes should be completed with Vinyl Chloride (VC) and dichloro-ethylene (DCE) • MTBE and BENZENE should be considered • Inclusion of Emerging Pollutants in monitoring plans
