with

areas,

...
suffer

from

contamination.
...
At

these

which

are

referred

to

as

megasites,

soil,

usually

polluted

with

a

of

of

For

megasites,

redevelopment

is

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

is

an

. 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 Some of the features of the former website has been removed, because they were outdated. This website presents the following subjects:
- basic strategies of the IMS,
- a manual for technical experts and environmental managers and
- examples of the implementation of the IMS at the Welcome megasite cases
