In order to maintain the volume of oil and gas supplies, the number of oil and gas wells is being increased every year, the construction of drilling platforms is built up and thus the amount of sludge and waste drilling mud, which has to be recycled, is increased proportionally. The research is dedicated to actualization of the danger of introducing chemical substances into various natural environments from industrial and anthropogenic sources on an example of drill cuttings from oil fields of Tomsk Oblast (Parabelsky and Kargasoksky regions). More than half of all wastes from the oil and gas industry are drilling wastes, which are type of mining waste (enclosing rocks and the like). Ecologists wage a fight for toughening Russian legislation by model experience of other countries.
The paper considers four directions for ensuring environmental safety during the deployment of the sludge. Now, methods of biotesting can be applied in the implementation of state and industrial environmental quality control of natural and waste water. These methods set forth in ruling document RD 118-02-90 "Guidance for determining biotesting of water toxicity, bottom sediments, pollutants and drilling muds". Using of biotesting with physical-chemical methods is established as regulatory requirements for water quality and is intended for Ministry of Natural Resources of the Russian Federation, territorial and subordinate organizations, also in scientific-research, design department and production organizations authorized to carry out works on biotesting.
In support of the importance of regarded work, two methods of biotesting are presented with the results allowing to classify the waste as 4-th class of hazard. It is allow to introduce changes in the Russian legislation to preserve the quality of the natural environment.
