on

large

(former)

industrial

sites
In Europe,
...
large
...
areas
...
and
...
regions
...
with
...
a
...
high
...
density
...
of
...
industry
...
(e.g.
...
sea
...
ports,
...
large
...
scale
...
chemical
...
industry
...
complexes,
...
metal
...
mining
...
areas,
...
military
...
complexes)
...
suffer
...
from
...
subsurface
...
contamination.
...
At
...
these
...
areas,
...
which
...
are
...
referred
...
to
...
as
...
megasites,
...
soil,
...
surface
...
water
...
and
...
groundwater
...
are
...
usually
...
polluted
...
with
...
a
...
mix
...
of
...
a
...
wide
...
variety
...
of
...
pollutants.
...
For
...
megasites,
...
redevelopment
...
combined
...
with
...
a
...
comprehensive
...
remediation
...
is
...
often
...
impossible
...
on
...
short
...
terms.
...
Remediation
...
costs
...
are
...
high,
...
thus
...
obstructing
...
an
...
economically
...
balanced
...
redevelopment
...
program.
...
On

the

other

hand,
...
severe
...
contamination
...
in

soil,
...
surface
...
water
...
and

groundwater
...
can
...
be
...
hazardous
...
for

humans
...
and

ecosystems
...
and

limit

use

Welcome is an acronym of Water, Environment and Landscape management at COntaminated MEgasites. The goal of the WELCOME-project was to make an Integrated Management Strategy (IMS) for Prevention and Reduction of risks at Contaminated Industrial Megasites. This IMS is a stepwise approach that takes the present situation as a starting point. A risk assessment that takes the soil-water system and the technical and economic feasilibity of the remediation actions into account, form the core of this methodology.
The WELCOME-project was funded by the European Union (FP5, EESD, EVK1-CT-2001-00103)
...
and
...
executed
...
from
...
January
...
2002
...
until
...
December
...
2004.
...
The
...
result
...
is
...
an
...
Integrated
...
Management
...
Strategy
...
for
...
Megasites
...
(IMS).
...
The
...
IMS
...
used
...
to
...
be
...
available
...
on
...
the
...
website
...
euwelcome.eu,
...
but
...
has
...
in
...
2013
...
been
...
transferred
...
to
...
this
...
location
...
due
...
to
...
technical
...
and
...
support-reasons.
...
The
...
reason
...
that
...
the
...
IMS
...
is
...
still
...
'alive'
...
is
...
because
...
many
...
of
...
its
...
subjects
...
are
...
still
...
actual
...
and
...
usefull.
...
Some
...
of
...
the
...
features
...
of
...
the
...
former
...
website
...
has
...
been
...
removed,
...
because
...
they
...
were
...
outdated.
