ISF-2 industrial site. According to the 2019 survey, of the 13 existing wells located at the ISF-2 site, only 3 were suitable for further regime observations. Analysis of hydrogeological conditions, sites of potential sources of pollution and possible leakage of process water into the environment, as well as the technical condition of existing observation wells allowed to justify drilling and equipment of 10 new observation wells to bring the network in a state adequate to the goals and objectives of radio-hydroelectric monitoring. Geological and technical equipment for drilling new observation wells was developed. Geological and technical outfits were developed for the liquidation of unsuitable observation wells. Scientific and engineering support (documentation of processes, quality control) of drilling of new wells and liquidation of old unusable wells is performed. Observation well passports have been developed. Industrial site near the NSC - SO complex. As of 2019, the depths of groundwater were 5.68 - 17.85 m, depending on the hypsometry of the surface of the local zone of the OS and the surrounding area, as well as seasonal fluctuations level of groundwater. At the same time, the depths of groundwater marks ranged from 107.36 (well 1-3A) to 109.25 m (wells 11-2A, C-24) depending on the areas of location and seasonal fluctuations. The complex of works on this site included measurements of level of groundwater, mathematical modeling, substantiation of placement and construction of observation wells. Geological and technical equipment for their drilling and equipment were developed for three observation wells. Product Description popup.authors popup.nrat_date 2020-10-01 Close
