The work of eliminating the residual pollution on the territory of the former Kohtla-Nõmme tire factory, which started in July, has now been completed. In total, nearly 14,000 m3 of heavily contaminated soil and 100 m3 of residual oil were removed.
The environmental pollution started from the state joint-stock company “Car Tires Repair Factory” that once operated in Kohtla-Nõmme. The following owners of the factory were also involved in the retreading of car tires until in 2001 when a check up was conducted on the pollution of the territory.
It was found that the tanks of the object's oil storage have been cut into metal and oil pollution has been caused. Toila municipality then cleaned the territory of tires, rubber waste and asbestos-containing materials. Four of the six containers were liquidated. However, the two tank bottoms with solid sediments remained in nature. An analysis conducted in 2013 revealed that the most dangerous source of pollution at the site is located in the area of the boiler house and above-ground heating tanks, where there was a thick, partially solidified layer of petroleum products on an area of 2,000 square meters.
According to Raimo Jaaksoo, project manager of the water department of the Ministry of the Environment, contaminated soil was excavated from an average depth of two meters. "Even the most polluted area in the area of old surface heating tanks was completely cleaned and there are no more semi-liquid oil residues on the ground. The spread of pollution has now been stopped and it will be possible to use the area again in the future, "said Jaaksoo.
In total, nearly 14,000 cubic meters of heavily contaminated soil and 100 cubic meters of oil residues were removed from the old tire factory. Contaminated soil was excavated from a depth of two meters until reaching the limestone layer. Even the most polluted area was completely removed - there are no more semi-liquid oil residues on the ground. Hopefully, the elimination of the residual pollution of the Kohtla-Nõmme plant will ensure the improvement of the groundwater status in the future and will bring beautiful life back to the Kohtla and Purtse rivers.< Back to news
