Dutch approach to complex soil and water problems
Status ISSWaP – Jiu (Integrated Solutions for Soil
and Water Problems)
Specialists views on fly-ash reuse and remediation
Interactive discussion on fly-ash association and
environmental measures
Collecting tasks for members of team who will visit
Holland and Germany
Setting priorities for follow-up projects
Bodem+ is een opdracht van het
Ministerie van VROM
Phases in the ISSWaP project
1. Preparation and quick scan visit (finalised)
2. Data inventory and conceptual modelling (95%
finished)
3. Synthesis of conceptual model (80% finished)
4a. Scoping the solution domain (30-49% finished)
4b. Solution and action workshop (today)
4c. Exposure and study visit (May)
5. Elaborating preferred solutions – final workshop
(week of 21-26 th of June)
Bodem+ is een opdracht van het
Ministerie van VROM
Three conceptual levels
1. Integrated approach
a. European Union (exchange Holland-Romania and other countries)
b. Social-economic possibilities and limitations / environment /
soil&water  regionally specific solutions
2. River Basin Management Plan (and other regional
plans)
3. Specific local environmental problems concerning for
example one fly-ash depot
Bodem+ is een opdracht van het
Ministerie van VROM
ISSWaP Jiu – overall conceptual model:
5 sources of pollution - 3 types of threatened objects
3.
Fly-ash depots: dust,
groundwater pollution,
waterlogging
2.
Power plants/industrial
zones: air and ground
pollution with a variety of
substances, point sources
1.
Open pit mining: dust,
radioactivity (?),
groundwater pumping
4.
Urban area: untreated
waste water, polluted
drinking water
5.
Agricultural area:
fertilizers and pesticides,
Diffuse pollution sources
8.
Nature/Ecosystems:
disorder, threat of
quality, degradation
of biodiversity
6.
7.
Groundwater / wells
different types of pollution
River system: siltation,
disordered waterbalance,
municipal and industrial
wastewater
Turceni
SE Turceni
Power plant
Heavy metals and
radioactive compounds in
topsoil due to (historical)
atmospheric deposition?
Valea Ceplea deposit
Ash & slag,
33 million m3 , 250 ha
High values for Ca, Mg, SO4
deep in groundwater affecting local
community. Local pollution with
heavy metals. Situation on
radioactive compounds unknown
Reserve storage (old)
Ash & slag,
8 million m3 , 107 ha
Possibly high values
for Ca, Mg, SO4 in shallow
groundwater. Local pollution with
heavy metals. Situation on
radioactive compounds unknown
Example Turceni Energy Complex
Conceptual model
SO2 3600-4800 mg/Nm3
NOx 370-470 mg/Nm3
Dust 101 – 130 mg/Nm3
GHG 6,4 million ton/yr
Heavy metals
Atmospheric emissions
Atmospheric emissions
(air erosion in municipality)
Dust 2-20 x MAC limit
MAC = 150 mg/Nm3

Industrial water
from Jiu
Heavy metals not very
Ca, Mg, SO4
Mobile
Stability of walls –
who controls and is responsible
Rise in
water table
H2SO4
Heavy metals
in topsoil?
Wells for
drinking water
(SO4 polluted ?)
Radioactivity
Needs analysis /
interpretation of (new?) measurements
Discharge of waste water
into Jiu river, including thermal
pollution > 35oC
Potable water, 5 l/s,
80-100 m bsl
