The village of Georgiyevka was severely contaminated in the 1993 Siberian Group of Chemical Enterprises accident. Villagers were evacuated; most houses were destroyed, even though the government tried to clean up the area. Only five households decided to stay. Many inhabitants of cities surrounding the Siberian Group of Chemical Enterprises and its workers have fallen ill. The SGCE is located in the closed city of Seversk and has had over 35 accidents in four decades. The town, once called Tomsk-7, was a secret city until 1992 and did not appear on official maps. The city still remains closed to non-residents. The last major accident took place in 1993. An explosion destroyed part of a reprocessing facility and an area of 200 square kilometers was contaminated with radioactive materials, resulting in evacuations and ongoing devastation. Radioactive materials from Europe are still processed by the SGCE and additional contamination stems from deliberate dumping of highly radioactive waste in the Tom River.
