There's Kozelsky pesticides landfill in the area. It was started there circa 1980, 35 km to Petropavlovsk-Kamchatsky. There were 108 tons of unusable pesticides. The spill comes from the river Nalycheva, and the landfill is on the river Mutnushka which flows into the Nalycheva river.

In the Central and North East Asia Region, the former Soviet Union has major hot spots for obsolete pesticides. A meeting held in Moscow on 7-8 February, 2001 by the Arctic Council for “The ecological reasonable management in field of stores of out-of-date pesticides“ project have identified priority Regions whereby the inventory of out-of-date pesticides should be documented. These Regions are the Kamchatka Peninsula, Krasnoyarsk Krai, Magadan Oblast, Sakha Republic (Yakutia) and Tyumen Oblast of the Russian Federation. Furthermore, inventory for out-of-date pesticides in three sub-boreal Regions have been identified: Altai Krai, Kurgan and Omsk Oblast (Shekhovtsov, 2002). Members of the Commonwealth of Independent States have a large quantity of PTS which are obsolete and redundant. A conservative estimate suggests there is greater than 150000 t of obsolete pesticides. Much is in poor condition and not properly managed (PAN UK, 2000).

The "reasonable" rubs me the wrong way. Not "safe", not "holistic", but "reasonable". As in something that doesn't put a noticable dent in some bottom line.
"After nearly two decades, Kamchatka recorded a net natural population growth instead of decline in 2007. However, in first half of 2008, the trend was reversed and population decline was observed again, partly due to an increased mortality rate among the rural population."
According to local media, there have already been leaks from buried pesticides. Regional agronomist Anatoly Fedorchenko said in 2006 that “this amount [20 tons of arsenic] is enough to poison the entire northern Pacific Ocean.” Although the landfill was mothballed in 2010, additional checks are now due to be carried out.
