The
...
WELCOME
...
IMS
...
is
...
a
...
stepwise
...
approach
...
to
...
establish
...
integrated
...
risk
...
based
...
management
...
plans
...
for
...
contaminated
...
megasites.
...
Such
...
management
...
plans
...
are
...
needed
...
for
...
complying
...
with
...
EU
...
directives
...
demanding
...
- Protection
...
- of
...
- the
...
- quality
...
- of
...
- surface
...
- and
...
- groundwater
...
- systems
...
- in
...
- Europe,
...
- and
...
- for
...
- that
...
- reason
...
- the
...
- Emission
...
- control
...
- of
...
- pollutants
...
- from
...
- regions
...
- containing
...
- large
...
- amounts
...
- of
...
- contaminants
...
- in
...
- soil,
...
- groundwater
...
- and
...
- sediment
...
- (Megasites),
...
- and
...
- To
...
- follow
...
- a
...
- risk-based
...
- approach,
...
- in
...
- order
...
- to
...
- comply
...
- with
...
- the
...
- proportionality
...
- principle,
...
- as
...
- defined
...
- in
...
- these
...
- EU
...
- directives.
...
More
...
specifically,
...
the
...
relevant
...
EU
...
directives
...
are
...
the
...
Water
...
Framework
...
Directive
...
and
...
the
...
GroundWater
...
Directive.
...
These
...
directives
...
demand
...
the
...
establishment
...
of
...
River
...
Basin
...
Management
...
Plans
...
for
...
all
...
European
...
rivers
...
and
...
associated
...
groundwater
...
systems.
...
Steps
...
to
...
complying
...
with
...
this
...
directive
...
are
...
the
...
WFD
...
River
...
Basin
...
Status
...
Reports
...
that
...
were
...
due
...
in
...
the
...
year
...
2005,
...
and
...
the
...
WFD
...
Programmes
...
of
...
Measures
...
due
...
in
...
the
...
year
...
2009.
...
Emission
...
control
...
through
...
risk-based
...
management
...
plans
...
for
...
contaminated
...
megasites
...
need
...
to
...
be
...
included
...
in
...
these
...
reports
...
by
...
land
...
-
...
and
...
river-basin
...
management
...
organisations
...
and
...
authorities,
...
since
...
these
...
regions
...
are
...
considered
...
to
...
be
...
a
...
major
...
group
...
of
...
contaminant
...
sources
...
affecting
...
the
...
quality
...
of
...
European
...
water
...
systems.
...
Such management plans are also needed for complying with national/regional
...
or
...
local
...
environmental
...
regulations
...
related
...
to
...
contaminated
...
land
...
and
...
groundwater.
...
Establishment of risk-based
...
management
...
plans
...
for
...
contaminated
...
megasites
...
is
...
difficult.
...
These
...
areas
...
are
...
large
...
and
...
complex
...
systems
...
from
...
various
...
perspectives:
...
- The
...
- hydro-geological
...
- structure
...
- Contamination
...
- pattern,
...
- and
...
- spreading
...
- and
...
- attenuation
...
- processes
...
- over
...
- time
...
- scales
...
- of
...
- decades
...
- to
...
- hundreds
...
- of
...
- years
...
- Land-use,
...
- current
...
- and
...
- in
...
- the
...
- future
...
- Many
...
- different
...
- stakeholders
...
- (industry,
...
- communities,
...
- authorities)
...
- Different
...
- authorities
