The state of the Kozelsk landfill for pesticides in Kamchatka requires its prompt liquidation. Scientists said that its surface began to erode.

Geophysical studies of the Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences, carried out in November, recorded the destruction of the layer and errors in the organization of the storage site for hazardous waste. Poisonous chemicals and pesticides lie there under the top layer of soil, on average two meters thick, to a depth of about eight meters.

According to the director of the institute, Aleksey Ozerov, a river network has formed on the surface of the landfill, which erodes the covering layer, which preserves the integrity of the burial. In addition, GPR studies did not find any clay layer or concrete base, which should isolate the polygon along its lower boundary.

The scientist also notes the erroneous choice of the site for the landfill. It is located in the alluvial cone of the Kozelsky volcano - this is a specific, active relief form - an accumulation of boulders, pebbles, sand and clay. In addition, such facilities are being built for up to 25 years, and the Kozelsk test site was equipped 40 years ago and its service life has long expired. In this case, the landfill is located in an earthquake hazardous zone. 

Previously, the leak from this storage of pesticides was considered one of the possible reasons pollution of ocean waters off the coast of Kamchatka. And although the suspicions were not confirmed, the authorities announced their intention reclaim burial. Reclamation will be included in the national project Ecology to attract federal funding for the work.
