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!

    Nicole, 31.10.03
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”
Nicole, 31.10.03
Problems
 Prevent and limit?
 Time frame: good quality < 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?
