Kemerovo Plastics Plant Systematically Dumped

The Kemerovo plastic plant systematically dumped waste water from production into the river, which is the source of the city’s drinking water supply. As a result of the pollution of the reservoir, the presence of substances harmful to humans tens of times exceeded the maximum permissible norms and posed a real threat to the health of the residents of the city of Kemerovo, which is confirmed by the conclusion of the sanitary-epidemiological service of the city. Residents of the city sent a collective complaint to the district prosecutor at the location of the enterprise and demanded to stop the discharge of untreated water into the river and hold the plant managers accountable. Based on the results of the complaint verification, the district prosecutor made a presentation to the director of the plastics factory in which he demanded that appropriate measures be taken to stop the discharge of untreated wastewater, the installation of treatment facilities and the issue of liability of officials responsible for violation of environmental laws that led to river pollution.
