Its important to say that the level of mine is under the level of Sitnica river that makes possible getting the water from river to the mine, this water washes out contaminated areas and than goes back to the river. After this process we can very much notice mine pollution in some parameters maybe ten times higher.
Ash dump Power plant Kosova A ( sample place M2). If we see from the surface area (around 150 ha) and also quantitative way of ash dump, this dump gets a very important place also in polluted aspect. Especially pollution is evident in period with bad weather e.g. big rains, in this case water connects polluted masteries in the dump and from draining they pass the pollution in Sitnica river. Often we have basic average, high concentration of phenols and other parameters that passes the limit of values that are permitted. Water delivered from ash dump have a pollution of third or fourth level of surface water pollution that effects the contamination of river Sitnica
