Introduction

• Thanks to Philippe Quevauviller for making his
  slides available
• Status of the GWD proposal accepted in
  interservice consultation
• implementation 18 months after entry into force,
  but WFD exists!

GROUNDWATER PROTECTION AGAINST POLLUTION
WFD requirements
80/68/EEC Directive
Daughter Directive
Environmental objectives (good status by 2015)
Prevent/limit pollutant discharges (authorisations
)
Criteria for good chemical status, protection
measures
Repeal planned in 2013 under the WFD
River basin management, protection measures
Specifications in support of WFD, no duplication
4

GROUNDWATER DAUGHTER DIRECTIVE (Art. 17 WFD)
PROPOSAL
Good chemical status
Pollution trend studies
Prevent/limit pollution
Existing EU wide standards and pollutant
thresholds for GW at risk
Links to measures, RBMP time frame, and point
sources of pollution
Consideration of direct and indirect discharges
Lists set out by MS, existing standards in force
Strengthening the no deterioration clause of WFD
Integration of relevant legislation
5
GOOD CHEMICAL STATUS
Basic criteria of the WFD
Pollutant thresholds
Quality standards
Defined in Annex V of the WFD
MS, GWB at risk MS, regional, GWB level lt 18
months, to Comm lt 22.06.06
Nitrates, pesticides and biocides under existing
legislation
Commission proposal on EQS within 12 months

IDENTIFICATION OF POLLUTANTS
For groundwater bodies that were characterised at
being at risk
Pollutants that may naturally occur
Specific synthetic pollutants
Study of background chemical composition
Links with analysis of pressures and impacts
7
Minimum list treshold values

• Naturally occurring
• ammonium
• arsenic
• cadmium
• chloride
• lead
• mercury
• sulphate

• Synthetic
• trichloroethylene
• tetrachloroethylene

8

PREVENTION AND LIMITATION OF POLLUTION
Framework to stop further pollution and reduce
existing pollution
Direct discharges
Indirect discharges
Control measures
Prohibition in accordance with 80/68/EEC and WFD
Specific trend assessment for point sources of
pollution
Prior investigations and authorisations
indirect discharges discharge after percolation
through soil
9

TREND IDENTIFICATION AND REVERSAL
Any significant and sustained upward pollution
trend should be reversed
Identification
Trend reversal
All pollutants

TRANSITIONAL ARRANGEMENTS
Prevent/limit pollution Continuation of
protection regime of Directive 80/68/EEC Link
with Article 11 of WFD
Direct discharges
Investigations, authorisations
Pollutant defined in GWD complementing List I of
80/68/EEC
Consideration of specifications on good chemical
status

WATER FRAMEWORK DIRECTIVE
Environmental objectives

GWD
2004 Characterisation, pressures and impacts
2004 Guidelines
2005 Economic study
2005 Expected adoption
2006 Monitoring, public participation
2006 Identification of GW pollutants

Link soil contamination

• trend assessment relevant pollutants in GWB
  affected by (historical) point sources to verify
  that plumes do not expand over a defined area and
  deteriorate chemical status of the GWB
• trend assessment in areas of GWB where trend
  might result in adverse effects on associated aq
  or terr ecosystems

15
Problems

• Prevent and limit?
• Time frame good quality lt 2015
• Decision trend reversal recommendation max 75
  threshold values
• Trend ID natural subst natural phenomena
• Focus stays at concentrations of selected
  pollutants
• Link soil GW quality?
