GROUNDWATER REBOUND IN -DRUZHBA- URANIUM MINE (SW BULGARIA) AFTER CESSATION OF MINING ACTIVITIES
Abstract
The ?Druzhba? uranium mine, near village of Eleshnitsa, Southwestern Bulgaria, was in operation from 1955 to 1992. During excavation work three different confined aquifers were registered ? at altitude of 805, 730 and 630 m. The original groundwater table was at 815 m and during the operation period it was reduced down to 520 m. After cessation of mining activities, the dewatering pumps (with approximate flow-rate of 300 m3/h) were stopped in December 1995, and then the deep mine galleries started to be flooded by groundwater. Subsequently, surface discharge of polluted water (with maximum uranium concentration of 4,6 mg/l) occurred in 2012, then the flow-rate has been continuously rising. The discharge water flows directly into Zlataritsa River. The main goal of the article is to evaluate the contribution of the three aquifers during the process of groundwater rebound as well as to predict when the groundwater table will reach its natural level. Additionally, the cumulative amount of uranium that has been transported into the surface water could be evaluated. The negative impact is limited and has only local significance because of very high dilution of mine water contaminants reaching the river water.
