Applying the Best Available Technologies concept in the substantiation  of the system of engineering protection of natural water from pollution

Summary

The contemporary science-methodical and regulatory base supposes the wide application of the Best Available Technologies principle including the implementation of environmental protection activities. As a result of studies and model simulations three basic causes of underground and surface water pollution on the considered territory of the Sosnovsk oil deposit in the Samara Area were identified: fracking that includes discharging produced and waste water into the stratum; industrial waste leakages from cushion holes and service wells; leakages from distribution pipelines and tanks with the subsequent filtration through the aeration zone into underground and surface waters. A mathematical model of underground water filtration with establishing a specialized information system was developed. Simulating filtration in operating strata where industrial wastewater is pumped provides for evaluating the pressure of the stratum and, consequently, the so-called adverse effect level that is determined by the ratio of the pressure in the stratum to the fracking pressure. The calculations of underground water filtration were carried out both under stationary and non-stationary conditions with the use of MODFLOW Model. The basic conceptual framework of the Best Available Technologies principle as applied to the problem of desi­gning the systems of engineering protection of underground and surface water from pollution is presented. The example of implemen­ting the presented conceptual framework in the location of landfills for produced and waste water discharges in the Samara Area is given. It was determined that the best option shall be chosen on the basis of the business and economic calculations.
