English Abstract A preliminary study has been performed to evaluate the
vulnerability of drinking water sources in the Netherlands to pollution by
(new) chemicals and to investigate the predictability of the removal of
organic micropollutants by drinking water treatment on the basis of data on
physico-chemical properties on the micropollutants. The results suggest
that from the octanol-water partition coefficient the removal effect by
coagulation, activated carbon filtration and grondwater recharge can be
predicted roughly. From the Henry coefficient, the removal of volatile
compounds during storage in open reservoirs and groundwater recharge can be
predictid. The data on biodegradability from EEC or OECD tests can be used
to estimate the removal during groundwater recharge under aerobic conditions
and by slow sand filtration.
