According to the governor, inspectors visited the Kozelsky toxic chemicals testing site on Tuesday, where they conducted visual surveillance and collected ground and water samples.
"The testing ground was surveyed from above, there were no visual indicators of a spill, but we will carefully monitor that facility," Solodov said, adding that the site's outside perimeter showed signs of breaches.
The governor made a similar observation concerning the Radyginsky testing site.
"There is no reason to suggest that there was a chemical spill there," he said.
The ministry also registered increased levels of petroleum products and phenol. Later, the head of the Ministry of Natural Resources and Environment of the Russian Federation, Dmitry Kobylkin, said that no chemical agents had been detected but did confirm a slight increase in phosphates and iron.
