The river Medetska in Sredna Gora Mountain, Bulgaria, is passing near the facilities of the closed state-owned cooper mine MOK Medet. Pollution of the river with cooper and manganese coming from the closed mine has been recorded and reported. These metals are dangerous for river biodiversity and public health.

According to the Regional Inspectorate of the Ministry of Environment and Waters, Plovdiv, Bulgaria, on 25 November 2008 the amount of lead in the River Chepelarska was 0.48mg/l, which is 9.6 times higher than the allowed amount (0.05mg/l). Even dead fish have started to appear along the river bed. The main dangers to human health after such disasters are related to soil pollution in fertile territories that may be flooded or irrigated with poisonous water and the pollution of underground waters used for drinking.

The Bulgarian Government has granted permission to the firm Gorubso Kardjali AD for a gold extraction installation using cyanide leaching technology. The installation had already been constructed without permission and it is located less than 1.000 meters from residential buildings and the city of Kardjali. Cyanide will pollute Arda River, and will cause transboundary pollution to Turkey and Greece, posing dangerous threats for public health.
