Description of project VODAMIN (2010 – 2013)
In regions of active mining and post-mining landscapes the natural water balance is
impaired. Negative effects are large and long-term changes in water quantity and quality of
groundwater, percolating water and surface water in the flowing and standing water bodies or
in drifts. In these areas, the implementation of the aims of the European Water Framework
Directive is particularly difficult.
Because of such mining consequences both Saxon and Czech mining areas are affected, a
cross-border Ziel-3-project (sponsored by European Regional Development Fund) called
VODAMIN was initiated. In this project, the region Ústí nad Labem (CZ), the Saxon Mining
Office, the Saxon State Office for Environment, Agriculture and Geology and the city
Oelsnitz/Erzgebirge are working together. Lead Partner is the Ústí region.

Project partner VODAMIN (2010 – 2013)
As part of this EU-project, cross-border joint actions have been established, dealing with the
effects of past and present mining activities on the water quality of ground and surface
waters.
This concern is illustrated by the name VODAMIN:
“VODA”
= water and
MIN
= mining.

Project area and key issues
The scope of VODAMIN contains parts of the following euro regions: Erzgebirge/Krušnohoří,
Neisse-Nisa-Nysa, Euregion Egrensis and Elbe/Labe. Directly integrated are:
Czech Republic: Ústecký kraj
Administrative district Saxony:
Bautzen, Görlitz, Erzgebirgskreis, Sächsische
Schweiz/Osterzgebirge
Quelle: Programmdokument Ziel 3
Within this scope, VODAMIN is concerned with regionally diverse impacts of surface and
underground mining. These include impacts of:
1. underground mining of tin in Zinnwald/Cínovec
2. lignite opencast mining in the Lusatia an the North Bohemia coal district
3. underground mining of pit coal in the coal district Lugau/Oelsnitz
As part of VODAMIN total of 34 sub-projects will be processed. These are mainly studies and
reports, performed with varying degrees of laboratory and field investigations.
In addition, two investment measures planned:
Construction of a groundwater measuring point in Lugau/Oelsnitz and a percolating-
and groundwater measuring point in the opencast mine Nochten
Pilot project: electrochemical sulphate reduction in the pilot plant of the mine water
treatment plant Rainitza

The 34 sub-projects fall into the following technical topics:
- Water balance in brown coal fields and post mining areas of northern Bohemia and
Lusatia (regarding surface-, percolating- and groundwater): Investigation of interactions
and impacts on the environment and infrastructure (chemical, ecological, quantitative
status / potential)
-
Cleaning of mining-impacted surface water, leachate, groundwater and mine water
-
Investigation and stabilization of the pits and surface water situation in the former ore and
coal mining in Zinnwald/Cinovec and Lugau/Oelsnitz
- Action plans for the restoration of the transboundary stream “Heerwasser” in
Zinnwald/Cínovec
-
Action plans for mining sites and post mining landscapes
